104 Chapter 3 Managing SAN Storage
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/) to replay the
journal:
$ sudo cvfsck -j volume
4 Check the volume to see if additional repairs are required:
$ sudo cvfsck -vn volume
5 If the report generated in the previous step lists additional problems, type the
following command to perform a full check and repair of the volume:
$ sudo cvfsck -v volume
For more information about this command, see the cvfsck man page.
