Chapter 8: Configure PSFS Filesystems 79
NOTE: If an attempt to mount the copied filesystem fails with an “FSID
conflict” error, run the following command. In the command,
<device> is the partition that contains the copied filesystem, and
<label> is the name that should be used to identify the filesystem.
psfslabel <device> “<label>”
Check a Filesystem
The psfscheck utility looks for a PSFS filesystem on a device, replays
transactions that are to be replayed, and either checks or repairs the
filesystem. The utility can also be used to enable or disable Full Zone Bit
Maps (FZBMs) on a filesystem. Before running psfscheck, be sure that the
volume is not in use.
The utility has the following syntax:
psfscheck [options] device
The device can be specified in several ways:
• By the drive letter, such as X:
• By the mount point (junction), such as C:\san\vol2
• By the psd or psv name, such as psd2p2 or psv3
Perform a Filesystem Check
If a filesystem is not unmounted cleanly, the journal will be replayed the
next time the filesystem is mounted to restore consistency. You should
seldom need to check the filesystem. However, if a filesystem was
corrupted by a hardware or software failure, you can repair it with the
psfscheck utility.
When psfscheck is running in default mode, it attempts to fix any
corruptions that can be fixed without using --rebuild-tree. The types of
corruption that can be fixed include bad pointers to data blocks, incorrect
st_size and st_blocks in a directory, directory entries pointing to
nowhere, incorrect file sizes and security descriptors, and objectid
sharing.
NOTE: The psfscheck utility requires exclusive access to the device. If it
cannot obtain this access, it will forcibly dismount the volume.
