1. Introduction
This Technical Brief assumes that the reader has a basic understanding of RAID (Redundant Array of Independent/Inexpensive Disks)
and the benefits of securing data on multiple disk arrays. For those
interested in learning more about RAID, please visit LaCie’s Tech-
nology Page and read our detailed White Paper.
IMPORTANT INFO: This Technical Brief offers a description of
Windows® Storage Server 2008 RAID implementation on the 5big
Storage Server. The information regarding RAID does not apply to
the 12big Rack Network since it includes a hardware RAID solution.

3. Removing and Installing
Disks
IMPORTANT INFO: In the event that an individual hard disk fails
in the LaCie 5big Storage Server, contact your LaCie reseller or
LaCie Customer Support for technical assistance. If the problem
drive was purchased from LaCie and it is within the warranty period,
please replace it with a hard drive provided by LaCie. LaCie will not
replace a non-LaCie hard drive or any hard drive purchased from
a third party.
Please note the following before replacing or adding a hard drive:
✦ Make certain to choose the slot with the problem drive.
✦ The LaCie 5big Storage Server drives may be hot after con-
tinuous use. Please use caution when removing one or more
drives from the enclosure.
✦ Use care when inserting or removing more than one disk while
the 5big Storage Server is powered on. If disks are rapidly
inserted or removed while the 5big Storage Server is turned
on, the system may not function properly or the drives will lose
recognition. You must wait at least ten seconds between each
insertion or removal of additional disk drives.
Please read the following sections if before purchasing a non-LaCie
disk:
3.1. MBR, GPT and the 5big Storage Server Operating System
3.2. Disk Model and Disk Sectors
3.3. Drives with Capacities Greater than 2TB

Technical Brief: RAID page 6
3.1. MBR, GPT and the 5big Storage
Server Operating System
Master Boot Record (MBR) partitioning has been the hard drive
standard for many years. It supports a maximum of four primary
partitions with a size limit of 2TB per partition. Due to partition limitations in the face of ever-expanding hard disk drive sizes, Global
Unique Identifier Partition Tables (GPT) now allows more partitions
with greater capacities. Further, GPT has additional advantages that
can enhance performance.
Please note that the 5big Storage Server operating system
must run on disks formatted with MBR. If the operating system
is stored on mirrored drives, both disks must be formatted
with MBR.
However, LaCie supports using data drives formatted with GPT.
Switching from MBR to GPT or, conversely, from GPT to MBR, is
not difficult. Please copy all important data to a separate disk before making the change since adjusting the partition table format is
destructive:
Right-click on My Computer and choose Manage. From the Man-age window select Disk Management and find your LaCie disk
drive. Right-click on the disk number to choose GPT or MBR.
3.3. Drives with Capacities Greater
than 2TB
At the time of this writing, disks larger than 2TB are not tested within
the 5big enclosure. Please note that LaCie cannot support disks
larger than 2TB without evaluating their performance, integrity, and
durability. With greater market adaptation, LaCie will incorporate a
wider range of drives into its rigorous qualification model. Please go
to www.lacie.com for periodic updates on the list of supported LaCie
and non-LaCie hard disks for the 5big enclosure.
The RAID configurations in this Technical Brief assume 1TB or 2TB
drives. Further, the examples include disks with the same capacity.
Administrators are advised to follow the default or recommended
configurations within this Technical Brief and to use two to five disks
of equal capacity within the enclosure.
You may experience problems when installing unsupported drives
in the 5big enclosure. For example, attempting to use one or two
3TB drives in the system mirror. Since the drive(s) must be formatted
with MBR to run Windows Storage Server 2008 on the 5big Storage
Server, the system only recognizes the first 2TB of storage. The administrator risks losing 1TB to 2TB of storage capacity.
Certainly, larger capacity external drives are recommended when
backing up the 5big Storage Server data via the USB 2.0 and eSATA
ports. Make certain to format external backup drives with capacities
greater than 2TB using GPT.
3.2. Disk Model and Disk Sectors
For optimal performance and to avoid potential conflicts, LaCie recommends that:
✦ non-LaCie drives used in the 5big enclosure are the same
model.
✦ the disk sectors among the 5big enclosure drives are equal.
Please check the specifications of the disk(s) for further information.
IMPORTANT INFO: LaCie cannot guarantee compatibility, per-
formance, or reliability when using non-LaCie disks that have not
been tested with the 5big enclosure.

3.4. Removing a Disk Tray
Adding a non-LaCie disk to an empty slot in the 5big Storage Server: The order of disks in the 5big enclosure can be
important. LaCie recommends inserting new drives in the order of
the numbered slots, from left to right. For example, if the first slot
on the left (Slot 1) contains the sole drive in the enclosure, choose
the second slot from the left (Slot 2) for the next drive. See 4. Disk
Numbering for additional information on disk numbering.
1. Use the included drive lock tool to unlock the drive tray. Turn the
lock until it is vertical. (Fig. 01)
2. Place your index finger into the space behind the handle. (Fig.
02)
3. Draw out the drive tray handle and carefully extract it. Please
use caution when removing the drive tray. (Fig. 03).
Adding a non-LaCie drive: Go to3.5. Fastening a non-LaCie Hard
Disk to the 5big Enclosure Drive Tray.

IMPORTANT INFO: Drives sold by LaCie are the preferred choice
for your 5big Storage Server. LaCie disks specially prepared for the
5big enclosure are tested and shipped in a drive tray for easy installation. Additionally, all 5big hard drives include a 3-year warranty.
Visit www.lacie.com for more information on purchasing a 5big disk
drive.
Please note the following before fastening your non-LaCie hard
drive to the drive tray:
✦ Only 3.5” SATA II drives may be used in the 5big enclosure.
Please visit the Support page at www.lacie.com for a list of
drives that have been tested by LaCie. LaCie cannot guarantee performance or compatibility with the 5big Storage Server
when using non-LaCie drives or drives that have not been
tested by LaCie.
✦ Use only the screws supplied in your packaging when fasten-
ing the non-LaCie hard drive to the drive tray (Fig. 04 - 5big
Drive Tray and Four Screws)
✦ To avoid potential problems caused by electrostatic discharge
(ESD), it is recommended that you do not touch the hard
drive’s printed circuit board (Fig. 05 - To prevent ESD, avoid
touching the hard drive printed circuit board). As a further
precaution against ESD, please use an anti-static wristband
or an anti-static mat to ground yourself when handling the
hard drive.

Technical Brief: RAID page 9
Fastening a disk to the drive tray:
1. Find a suitable work area with adequate space and a flat, even
surface.
2. Locate the empty 5big drive tray and four drive tray screws included in your packaging. Do not fasten a disk to a 5big enclosure drive tray with alternative screws. Doing so may damage
the drive tray as well as your non-LaCie disk. Make certain that
your non-LaCie 3.5” SATA II disk and a Phillips head screwdriver are within reach as well. Please confirm that the head
of the screwdriver is the proper size for the drive tray screws
provided by LaCie.
3. Place the empty drive tray onto the flat work area. The handle
should be on the bottom left, with the lock icon pointing away
from you (Fig. 06).
4. With its label side facing up, gently place the hard disk within
the drive tray (Fig. 07). The four tray screw slots should be neatly
aligned with the disk’s four screw holes. Please note that the
printed circuit board will be flat on the work space and the SATA
connector facing to the right.
5. Using the Phillips head screwdriver, carefully fasten all four
screws into their slots. Do not overly tighten the screws. Doing so may negatively affect the integrity of the screw holes on
the drive as well as the threads on the screws (Fig. 08).
6. Go to 3.7. Insert a Disk for details on inserting the disk tray into
the 5big enclosure.

3.6. 5big Enclosure Numbered Slots
and Disk Trays
For convenience when adding or removing disks, the 5big enclosure
drive slots and trays have matching numbers (Fig. 09).
IMPORTANT INFO: The order of disks in the 5big enclosure can
be important. LaCie recommends inserting new drives in the order
of the numbered slots, from left to right. For example, if the first slot
on the left (Slot 1) contains the sole drive in the enclosure, choose
the second slot from the left (Slot 2) for the next drive.
3.7. Insert a Disk
7. Make certain that the replacement or new drive is securely fas-
tened to a drive tray. See 3.5. Fastening a non-LaCie Hard Disk
to the 5big Enclosure Drive Tray if you are adding a non-LaCie
drive.
8. Carefully insert the drive tray into the empty drive slot. You will
feel resistance when the drive tray is most of the way in the bay.
Gently push the drive tray handle firmly until you feel the drive
snap into place. The drive tray handle should be flush with the
back of the 5big enclosure.
9. Use the drive lock tool to lock the drive in place.
10. Please read 4. Disk Numbering before configuring the 5big
Storage Server RAID. To begin configuring the RAID go to:
✦ Five Disk Server: 5. RAID - Five Disk Server
✦ Four Disk Server: 8. RAID - Four Disk Server
✦ Three Disk Server: 7. RAID - Three Disk Server
✦ Two Disk Server: 6. RAID - Two Disk Server

4. Disk Numbering
The 5big Storage Server uses Windows Storage Server Disk Management to configure RAID. Before reading how to create and repair
the RAID arrays, it may be helpful to know how the utility assigns
numbers to the physical disks. Please note that disk number assignment in Disk Management differs from the LaCie Hardware Monitor
(see Technical Brief: LaCie Hardware Monitorand 4.2. Disk Num-
bering: LaCie Hardware Monitor).
4.1. Disk Numbering: Windows Disk
Management
MANUAL NOTE: To best demonstrate disk numbering, this sec-
tion uses the LaCie default configuration of a 5big Storage Server
with five disks. The amount of disks as well as the RAID configurations may appear different based upon your 5big Storage Server.
Fig. 10
Fig. 10 illustrates how Windows Disk Management lists the default
5big Storage Server RAID configuration: disk numbers, levels of
RAID, and the health of the disks. Fig. 11 shows how the Windows
Disk Management numbers correlate with the physical placement
of the disks. (See 5.1. Default RAID for further information on the
default RAID settings for a five disk 5big Storage Server.)
Please note that each disk takes part in two RAID configurations.
For example, approximately 35 GB of Disk 0 is part of a mirror that
runs the Windows Storage Server operating system. The remainder
of Disk 0 is also one of five drives that make up the Data volume,
a RAID 5 array.
During standard operation, the numbering will not change. However, if a disk should fail, the default disk numbering could become
confused, especially if the 5big Storage Server is restarted when a
disk is missing. Missing could indicate:

In Fig. 12 and Fig. 13, Disk 1 has been physically removed from its
slot. Disk Management no longer has a Disk 1 but a Missing disk.
The other four disks keep their default number assignments since the
5big Storage Server has not been restarted.
Fig. 12
Due to the way in which Windows assigns drive numbers, LaCie
highly recommends troubleshooting and, if necessary, replacing a
Missing disk before rebooting the 5big Storage Server. (See 9. Re-
pairing RAID Configurations for further information on replacing or
repairing a failed or missing disk.) If the system restarts before the
Missing disk is repaired, Windows will reassign numbers to the re-
maining disks based upon their physical order.

In our example, Disk 1 was removed from its slot, becoming the
Missing disk in Windows Disk Management. If the 5big Storage
Server is restarted with the empty slot, Windows will assign new numbers to three of the five drives (Fig. 14 and Fig. 15):
✦ Disk 0 remains Disk 0
✦ Disk 2 becomes Disk 1
✦ Disk 3 becomes Disk 2
✦ Disk 4 becomes Disk 3
The Missing disk will remain on the list until it is manually removed
from Disk Management (9.2.1. Removing the Missing Disk).
Fig. 14
Slight confusion could occur when a replacement disk is inserted
into the empty slot after the 5big Storage Server reboots (Fig. 15,
b). While the slot once had a disk that Windows recognized as Disk
1 (Fig. 10 and Fig. 11), that number is now taken by another drive
(Fig. 15, c).

When a replacement drive is inserted into the empty slot, Windows
assigns the next available number, Disk 4 (Fig. 16 and Fig. 17, b).
Certainly, drive renumbering is not a problem that will impact the
integrity of the data. However, it may become difficult to manage
and troubleshoot due to the irregular order of the disks. Consider
that, in this example, Disk 0 will have to be paired with Disk 4 for
the mirrored System volume, disrupting the order seen earlier in Disk
Management (Fig. 10).

4.1.1. Recovering the 5big Storage Server
Default Disk Order
While not imperative to optimal operation, you can easily recover
the 5big Storage Server default drive order by restarting the device.
Please make certain that the 5big Storage Server is not being accessed before restarting it.
After the reboot, the Unallocated replacement disk is reassigned,
moving from Disk 4 (Fig. 16) to Disk 1 (Fig. 18).

5.1. Default RAID
The default RAID configurations for the 5big Storage Server are
based upon the general requirements of an active business that
wants to keep data and the server operating system safe. While LaCie believes the default RAID configurations to be suitable for most
networks, there may be environments that require an alternative setup. Since any change in RAID for one or multiple volumes will delete
data, administrators should consider the solutions that best suit the
needs of an office before using the server.
EXAMPLE: A Share (see Technical Brief: Shared Folders) called
Finance Reports 2009 has been created on the volume Data. This
Sharecontains all important financial documents from the year
2010. Data, by default, is a RAID 5 volume. If an administrator
decides to break up the Data volume in favor of creating mirrored
volumes, the Share Finance Reports 2009 and all of its files will be
deleted.
rays should read this section if they have five disks installed in their
5big Storage Server. Please see 6. RAID - Two Disk Server, 7. RAID
- Three Disk Server, and 8. RAID - Four Disk Server for information
on alternative disk configurations.
LaCie highly recommends that customers backup all data stored on
their professional server. You may use USB 2.0 or eSATA external
desktop drives by connecting them to the server ports or backup to a
separate network server. If all files on the LaCie server are regularly
backed up, the risk of losing data when adjusting RAID configurations is dramatically reduced.

IMPORTANT INFO: Mirroring and RAID 5 provide solid protection
if one drive in their respective volumes should encounter problems.
However, LaCie highly recommends backing up the data stored on
your professional server regularly in order to guard against worst
case scenarios (i.e. accidental data deletion, malicious programs,
viruses, etc.). LaCie professional servers include USB 2.0 and eSATA
ports to attach desktop drives for use as backup storage. You can
also backup your data to another server on the network.

5.3. Five Disks: System Volume

In this example, Disk 0, volume letter C contains the Windows Storage Server operating system. Note that System is listed in its contents
(Fig. 20). The operating system, as shipped, takes up 35 GB on
Disk 0.
Fig. 20
5.3.1. Boot Order and Creating the Mirror
After a Recovery
All Windows Storage Server system files are duplicated on each disk
in the mirror. In most instances, when there are two versions of a
Windows operating system, the user is prompted to select one as the
device boots. Since a monitor and keyboard are required to choose
the boot disk, your 5big Storage Server has turned off this option to
save the user time when booting the device.
EXAMPLE: By default, the 5big Storage Server boots from the first
disk with an operating system. In this case, that is Disk 0 (Fig. 20). If
Disk 0 should experience a problem or the operating system is damaged, the 5big Storage Server will boot from Disk 1 without forcing
any action from the user. However, this option will be lost if the user
has performed a recovery, reinstalling Windows Storage Server.
continued on the next page>>
Page 21
LaCie Professional Server RAID - Five Disks
Technical Brief: RAID page 21
In the scenario where Disk 0 fails some time after a recovery, the
front LED will blink continuously since it cannot boot from the first
drive with an operating system. The administrator may feel a bit
inconvenienced by having to connect a monitor, keyboard, and
mouse to the 5big Storage Server in order to choose Disk 1 as the
boot disk.
To keep the 5big Storage Server boot order, type or copy and paste
the following commands into Command Prompt before mirroring
the system disk (Go to Start>Command Prompt or Start>Run
and type cmd.):
bcdedit /set {current} osdevice boot
bcdedit /set {current} device boot
bcdedit /set {bootmgr} device boot

5.6. Volume Activity During a
Resynch
5.6.1. Rebooting During a Resynch
Rebooting the 5big Storage Server while Disk Management is Resynching a mirror or RAID 5 volume will not harm the configuration
or its data. However, since the process was interrupted, Disk Management will automatically start a new resynch at 0% once the 5big
Storage Server has rebooted.
Due to the size of large volumes such as the 5big Storage Server
Data (RAID 5), rebooting during a resynch in progress could extend
the operation for many hours.
5.6.2. Accessing Data on a Volume that is
Resynching
A volume that is in the midst of a resynch may be accessed by workstations on the network. Users can read or write to the volume. However, performance will be degraded while Windows Storage Server
is rebuilding the mirror and/or RAID 5.

6. RAID - Two Disk Server
A 5big Storage Server with two drives offers many options for the
user, including the RAID configuration. While it is possible to create
Spanned disks or a RAID 0 array, LaCie highly recommends mirroring for optimal protection of your data. RAID 0 can offer some speed
advantages but data will not be duplicated across both volumes as
with mirroring. Users risk losing data if one of the disks should fail.

regularly in order to guard against worst case scenarios (i.e. accidental data deletion, malicious programs, viruses, etc.). LaCie professional servers include USB 2.0 and eSATA ports to attach desktop
drives for use as backup storage. You can also backup your data to
another server on the network.

6.3. 5big Storage Server Single Disk
Default Configuration
A single disk 5big Storage Server is shipped with two partitions, System and Data. Fig. 45, shows both partitions on the sole hard drive,
Disk 0. Volume C contains the Windows Storage Server operating
system and volume D the Data volume. The operating system partition, as shipped, takes up 35 GB.
Fig. 45
For details on adding a second disk to the 5big enclosure, please
go to 3. Removing and Installing Disks. Once the disk has been
installed, please go to 6.4. Boot Order and Creating the System
Mirror.
Page 39
LaCie Professional Server RAID - Two Disks
Technical Brief: RAID page 39
6.4. Boot Order and Creating the
System Mirror
All Windows Storage Server system files are duplicated on each disk
in the mirror. In most instances, when there are two versions of a
Windows operating system, the user is prompted to select one as the
device boots. Since a monitor and keyboard are required to choose
the boot disk, your 5big Storage Server has turned off this option to
save the user time when booting the device.
EXAMPLE: By default, the 5big Storage Server boots from the first
disk with an operating system. In this case, that is Disk 0 (Fig. 20). If
Disk 0 should experience a problem or the operating system is damaged, the 5big Storage Server will boot from Disk 1 without forcing
any action from the user. However, this option will be lost if the user
has performed a recovery, reinstalling Windows Storage Server, or is
adding additional drives to a single disk 5big Storage Server.
In the scenario where Disk 0 fails some time after a disk is added to
a single disk 5big Storage Server, the front LED will blink continuously since it cannot boot from the first drive with an operating system. The administrator may feel a bit inconvenienced by having to
connect a monitor, keyboard, and mouse to the 5big Storage Server
in order to choose Disk 1 as the boot disk.
To keep the 5big Storage Server boot order, type or copy and paste
the following commands into Command Prompt before mirroring
the system disk (Go to Start>Command Prompt or Start>Run
and type cmd.):
bcdedit /set {current} osdevice boot
bcdedit /set {current} device boot
bcdedit /set {bootmgr} device boot
bcdedit /set {memdiag} device boot

7. RAID - Three Disk Server
The directions that follow will help you to create the recommended
RAID configuration for a 5big Storage Server with three disk.
7.1. Three Disk Suggested RAID
Configuration
While it is possible to create Spanned disks or RAID 0 arrays, LaCie
highly recommends mirroring and RAID 5 for optimal protection of
your data. RAID 0 can offer some speed advantages but data will
not be protected across multiple volumes as with mirroring and RAID
5. Users risk losing data if one of the disks should fail with RAID 0.
IMPORTANT INFO: Mirroring and RAID 5 provide solid protection
if one drive in their respective volumes should encounter problems.
However, LaCie highly recommends backing up the data stored on
your professional server regularly in order to guard against worst
case scenarios (i.e. accidental data deletion, malicious programs,
viruses, etc.). LaCie professional servers include USB 2.0 and eSATA
ports to attach desktop drives for use as backup storage. You can
also backup your data to another server on the network.

must run from its own
volume.
✦ Storing data on the sys-
tem volume will impact
server performance.
✦ A swap, or paging file
improves server performance by extending the
device’s physical memory. The swap file may be
created on a non-system
volume, acting as virtual
memory. See 5.4.2. Cre-
ate the Swap File.
✦ Due to its size, the Swap
volume may be used
for applications that are
installed on the 5big

8.5. Data Volume: RAID 5
1. Launch Disk Management (8.2. Adjusting the RAID). Please note
that Disk 0 may have an active partition Data (D:). To create the
RAID 5 array using Disks 0, 1, and 2, we must have three Unal-
located partitions. Therefore, the Data (D:) partition will be de-
leted before building the RAID 5. Since deleting the volume will
also remove the files stored on the Data (D:) partition, please
back up all data before moving to the next step. To delete the
partition, right-click on Data (D:) to select Delete Volume...
and click Yes at the Windows prompts. See 7.7. Data Volume:

9. Repairing RAID Configurations
9.1. Reinserting a Healthy Disk
If you accidentally remove a healthy disk from the 5big Storage Server while it is on, the system must reactivate and resynch the RAID(s).
For example, if Disk 1 is not causing errors but has been removed,
the System mirror and Data RAID 5 are no longer Healthy. In Fig.
105, the disk that has been removed is Missing. Further, the System
and Data configurations show Failed Redundancy.
Fig. 105
It is a simple procedure to reactivate the RAID when a healthy disk
has been removed from an active 5big Storage Server.

Technical Brief: RAID page 78
1. Reinsert the healthy disk into its slot on the 5big Storage Server
(3. Removing and Installing Disks).
2. Disk Management will recognize the reinserted disk but the
Failed Redundancy persists until the RAIDs are reactivated (Fig.
106).
Fig. 106
3. Right-click on one of the mirrored disks and select Reactivate Disk (Fig. 107).

4. In this example, there is no need to perform the step a second
time since Disk Management will rebuild the System mirror and
the RAID 5 Data configurations at the same (Fig. 108). Please
be patient as Resynching the RAID 5 Data volume will take quite
some time.
Fig. 108
9.2. Repairing the System Mirror
and RAID 5 After a Disk Failure
You must recreate the System mirror and/or repair the RAID 5 when
a disk has failed and you receive a replacement disk from LaCie.
IMPORTANT INFO: In the event that an individual hard disk fails
in the LaCie 5big Storage Server, contact your LaCie reseller or
LaCie Customer Support for technical assistance. If the problem
drive was purchased from LaCie and it is within the warranty period,
please replace it with a hard drive provided by LaCie. LaCie will not
replace a non-LaCie hard drive or any hard drive not purchased
from LaCie. Please note that the replacement disk capacity should
be equal to the original disk. While you may use a disk with more
capacity, RAID configurations only recognize the size of the original
disk. This means that the additional capacity of a new disk would
be ignored.

Technical Brief: RAID page 80
1. If it is not open, launch Disk Management (Server Manager
> Storage > Disk Management). This example assumes that
the disk has failed and that a replacement from LaCie is available to repair the RAIDs.
2. Note that Disk 1 is Missing and that both the System mirror
and Data RAID 5 have Failed Redundancy (Fig. 109). The Swap
volume is Healthy since all three of its disks are unaffected by
the Disk 1 failure.
Fig. 109
3. Remove the failed disk and insert the replacement (see 3. Re-
moving and Installing Disks).

9.2.1. Removing the Missing Disk
Disk Management must be told to remove the Missing disk once
Resynching has begun. Follow the easy steps below to delete the
Missing disk from the list of drives.
1. If you have not closed Disk Management after following the
steps to repair the System mirror and/or Data RAID 5, the Miss-
ing disk will be listed as a member of the Data volume (Fig.
119).
Fig. 119
2. Go to the the Action pulldown menu and choose Refresh
(Action>Refresh) to refresh the list of drives. If the Missing
disk is still listed as Data, exit and relaunch Disk Management
(Server Manager>Storage>Disk Management).

9.2.2. Replacing Disk 0
Replacing and repairing Disks 0 and 1 require the same series of
steps. The one difference is how the system will react to a reboot
while the System mirror is resynching.
If the 5big Storage Server restarts while Disk 1 is being replaced and
resynching, the server will have no problem finding a bootable operating system on Disk 0. However, if Disk 0 is being replaced and the
5big Storage Server restarts during the System mirror resynch, the
device will hang. In this unique case, the 5big Storage Server cannot
find a bootable operating system on the first logical drive.
If the System mirror resynch is interrupted and the 5big Storage Server hangs, unplug Disk 0 from the back of the unit. With Disk 0 briefly
disassociated from the 5big Storage Server, it can find a bootable
operating system on Disk 1.
Once the 5big Storage Server has restarted, reinsert Disk 0 and
return to Disk Management to finish resynching the System mirror
(9.2. Repairing the System Mirror and RAID 5 After a Disk Failure).
9.2.3. Rebooting During a Resynch
Restarting the 5big Storage Server while it is resynching a mirror or
a RAID 5 array will not harm data or the integrity of the volume.
The sole drawback of rebooting the device during a resynch is lost
time. An interrupted resynch does not pick up where it left off once
the 5big Storage Server has restarted. Instead, the resynch will start
again from 0%.
