Volume Availability During Upgrade
You can update Xsan 2 to Xsan 2.1 without interrupting volume availability. However,
upgrading from Xsan 1.4 includes activities such as converting file-system data
structures that prevent users from accessing volumes during the upgrade.
Important:
from Xsan 1.4. The file-system conversion phase of the upgrade can take from less than
an hour to more than a day, depending on the size of your volumes. Be sure to notify
client users that the volumes will be unavailable.
You must unmount your SAN volumes from clients during the upgrade
Mac OS X or Mac OS X Server?
The Xsan file system, the Xsan Admin application, and the Xsan User Quotas
application run identically on Mac OS X and Mac OS X Server. Any statement in this
guide about Mac OS X also applies to Mac OS X Server.
