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/) to check the
volume without making repairs:
$ sudo cvfsck -vn volume
where volume is the name of an Xsan volume. You’ll see a warning that the journal is
active; this is normal.
For more information about this command, see the cvfsck man page.
