56 Chapter 3 Managing SAN Storage
Checking the Integrity of a Volume
If SAN users are having trouble accessing files, you can use the cvfsck command to
check the integrity of a volume, its metadata, and files.
To check a volume:
1 Open Terminal (in /Applications/Utilities).
2 If you are not working at the SAN controller computer, use SSH to log in to the
controller remotely:
$ ssh user@computer
where user is an administrator user on the controller computer and computer is the
controller’s name or IP address.
3 Run the cvfsck command-line utility (in /Library/Filesystems/Xsan/bin) twice; once to
check the journal and again to check the volume:
$ sudo cvfsck -j volume
$ sudo cvfsck -n volume
where volume is the name of an Xsan volume.
For more information on using this command, see the cvfsck man page.
Repairing a Volume
If the cvfsck utility reveals problems with a volume, you can use the same command
to repair the volume.
To repair a volume:
1 Stop the volume.
Open Xsan Admin, select the volume, and click Stop Volume.
2 Open Terminal (in /Applications/Utilities).
If you are not working at the SAN controller computer, use SSH to log in to the
controller remotely:
$ ssh user@computer
where user is an administrator user on the controller computer and computer is the
controller’s name or IP address.
3 Run the cvfsck command-line utility (in /Library/Filesystems/Xsan/bin).
$ sudo cvfsck volume
For more information on using this command, see the cvfsck man page.
