From the Ubuntu system menu at the right of the desktop menu bar, choose
System Settings and in the System Settings window that opens, click Displays.
b)
In the Displays window that opens, make the changes to the display settings that
you want and click Apply.
High-resolution displays consume a large quantity of GPU memory. If you have
connected three 4K displays to the DGX Station, they may consume most of the GPU
memory on the NVIDIA Tesla V100 GPU card to which they are connected, especially if
you are running graphics-intensive applications.
If you are running memory-intensive compute workloads on the DGX Station and are
experiencing performance issues, consider conserving GPU memory by reducing or
minimizing the graphics workload.
To reduce the graphics workload, disconnect any additional displays you connected
‣
and use only one display with the DGX Station.
If you disconnect a display from the DGX Station, the disconnection is automatically
detected and the display settings are automatically adjusted for the remaining
displays.
To minimize the graphics workload, shut down the LightDM display manager and
‣
use secure shell (SSH) to log in to the DGX Station remotely.
www.nvidia.com
DGX Station DU-08255-001 _v2.1|14

To enable multiple users to access the DGX Station remotely, secure shell (SSH) server is
installed and enabled on the DGX Station.
Add other Ubuntu OS users to the DGX Station to allow them to log in remotely to the
DGX Station through SSH.
For information about how to add a user, see Add a new user account (https://
help.ubuntu.com/16.04/ubuntu-help/user-add.html) in the Ubuntu Official
Documentation. For information about how to log in remotely through SSH, see
Connecting to an OpenSSH Server (https://help.ubuntu.com/community/SSH/OpenSSH/
ConnectingTo) on the Ubuntu Community Help Wiki.
The DGX Station does not provide any additional isolation guarantees between users
beyond the guarantees that the Ubuntu OS offers. For guidelines about how to secure
access to the DGX Station over SSH, see Configuring an OpenSSH Server (https://
help.ubuntu.com/community/SSH/OpenSSH/Configuring) on the Ubuntu Community
Help Wiki.
2.9.Preparing the DGX Station for Use with
Docker
Some initial setup of the DGX Station is required to ensure that users have the required
privileges to run Docker containers and to prevent IP address conflicts between Docker
and the DGX Station.
2.9.1.Enabling Users To Run Docker Containers
To prevent the docker daemon from running without protection against escalation of
privileges, the Docker software requires sudo privileges to run containers. Meeting this
requirement involves enabling users who will run Docker containers to run commands
with sudo privileges. Therefore, you should ensure that only users whom you trust
www.nvidia.com
DGX Station DU-08255-001 _v2.1|15
Setting Up the NVIDIA DGX Station
and who are aware of the potential risks to the DGX Station of running commands with
sudo privileges are able to run Docker containers.
Before allowing multiple users to run commands with sudo privileges, consult your IT
department to determine whether you would be violating your organization's security
policies. For the security implications of enabling users to run Docker containers, see
Docker daemon attack surface.
You can enable users to run the Docker containers in one of the following ways:
Add each user as an administrator user with sudo privileges.
‣
Add each user as a standard user without sudo privileges and then add the user
‣
to the docker group. This approach is inherently insecure because any user who
can send commands to the docker engine can escalate privilege and run root-user
operations.
To add an existing user to the docker group, run this command:
$ sudo usermod -aG docker user-login-id
user-login-id
The user login ID of the existing user that you are adding to the docker group.
2.9.2.Preventing IP Address Conflicts Between Docker
and the DGX Station
To ensure that the DGX Station can access the network interfaces for Docker containers,
configure the containers to use a subnet distinct from other network resources used
by the DGX Station. By default, Docker uses the 172.17.0.0/16 subnet. If addresses
within this range are already used on the DGX Station network, change the Docker
network to specify the bridge IP address range and container IP address range to be
used by Docker containers.
This task requires sudo privileges.
1.
Open the /etc/systemd/system/docker.service.d/dockeroverride.conf file in a plain-text editor, such as vi.
$ sudo vi /etc/systemd/system/docker.service.d/docker-override.conf
2.
Append the following options to the line that begins ExecStart=/usr/bin/
dockerd, which specifies the command to start the dockerd daemon:
--bip=bridge-ip-address-range
‣
--fixed-cidr=container-ip-address-range
‣
bridge-ip-address-range
The bridge IP address range to be used by Docker containers, for example,
192.168.127.1/24.

LimitMEMLOCK=infinity
LimitSTACK=67108864
Starting with DGX OS Desktop release 3.1.4, the option --disable-legacy-
registry=false is removed from the Docker CE service configuration file
docker-override.conf. The option is removed for compatibility with
Docker CE 17.12 and later.
3.
Save and close the /etc/systemd/system/docker.service.d/dockeroverride.conf file.
4.

4.6.Maintaining the DGX Station Persistent
Storage
The DGX Station persistent storage consists of SSDs for data storage and the operating
system. As supplied from the factory, these SSDs are configured as described in System
Memory and Storage.
4.6.1.Changing the RAID Level of the RAID Array
As supplied from the factory, the RAID level of the DGX Station RAID array is RAID 0.
RAID 0 provides the maximum storage capacity, but does not provide any redundancy.
www.nvidia.com
DGX Station DU-08255-001 _v2.1|33
Maintaining and Servicing the NVIDIA DGX Station
If a single SSD in the array fails, all data stored on the array is lost. If you are willing to
accept reduced capacity in return for some level of protection against failure of a single
SSD, you can change the level of the RAID array to RAID 5. If you change the RAID level
from RAID 0 to RAID 5, the total storage capacity of the RAID array is reduced from
5.76 TB to 3.84 TB.
Before changing the RAID level of the DGX Station RAID array, back up all data on the
array that you want to preserve. Changing the RAID level of the DGX Station RAID
array erases all data stored on the array.
The DGX Station software includes the custom script configure_raid_array.py,
which you can use to change the level of the RAID array without unmounting the RAID
volume.
To change the RAID level to RAID 5, run the following command:
‣
$ sudo configure_raid_array.py -m raid5
To change the RAID level to RAID 0, run the following command:
‣
$ sudo configure_raid_array.py -m raid0
To confirm that the RAID level was changed as required, run the lsblk command. The
entry in the TYPE column for each SSD in the RAID array indicates the RAID level of the
array.
The following example shows that the RAID level of the array is RAID 0. The name of
the RAID volume is md0 and the mount point of the volume is /raid.
~$ lsblk

If you replaced an SSD in the RAID array, rebuild the RAID array as explained in
‣
Rebuilding the DGX Station RAID Array.
If you replaced the OS SSD, restore the software image as explained in Restoring the
‣
DGX Station Software Image.
4.6.5.Rebuilding the DGX Station RAID Array
If the DGX Station RAID array is degraded because an SSD failed, replace the SSD as
explained in Replacing an SSD.
After replacing a failed SSD in the RAID array, you must rebuild the array to
add the new SSD to a RAID 0 array or to regenerate the lost data on the new
SSD in a RAID 5 array. The DGX Station software includes the custom script
configure_raid_array.py for this purpose.
To rebuild the array, run the following command:
$ sudo configure_raid_array.py -r
The time required to rebuild a RAID 5 array depends on factors such as system load,
SSD capacity, and the number of SSDs in the array. Rebuilding the array of three, 1.92terabyte SSDs in the DGX Station may require several hours.
You can monitor the progress of a long-running rebuild by examining the contents of the
/proc/mdstat file:
$ cat /proc/mdstat
Personalities : [raid0] [linear] [multipath] [raid1] [raid6] [raid5] [raid4]
[raid10]
md0 : active raid5 sdb[0] sdd[3] sdc[1]

finish=438.3min speed=68419K/sec
bitmap: 2/14 pages [8KB], 65536KB chunk
unused devices: <none>
In this example, the rebuild is 4.0% complete and the rebuild is estimated to finish in
438.3 minutes.
The RAID array is rebuilt with its existing RAID level.
If the array is a RAID 0 array, all data that was on the array is erased after array is
