Chapter 2: HP Clustered File System Commands 30

psdctl.exe – display device bindings

Synopsis

bin\psdctl

Description

This command should be run only at the request of HP personnel.

psfscheck.exe – check or repair a filesystem

Synopsis

bin\psfscheck [options] device

Description

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. This utility can also be used to enable or disable Full Zone Bit

Maps (FZBMs), to enable sparse files, to enable or disable quotas, and to set

quota options for a filesystem. Before running psfscheck, be sure that the

volume is not in use.

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

Check a filesystem

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.
