Chapter 1: HP Clustered File System Commands 36

psfsdebug – get PSFS filesystem image

Synopsis

/opt/hpcfs/tools/psfsdebug -p <device>

psfsdebug -P <device>

Description

When used to obtain a PSFS filesystem image, the psfsdebug command

extracts all metadata from the specified filesystem and sends it to stdout.

The -p option compresses the data, while the -P option does not.

<device> is either the special file corresponding to the psd or psv device or

the corresponding local device if psd or psv drivers are not loaded.

-p is the best option for a filesystem that is not corrupted, as the resulting

output is smaller. With corrupted filesystems, there is a risk that the -p

compression algorithm will be affected by the corruption and the

unpacked metadata will not be identical to the original.

See “psfsunpack – unpack a PSFS filesystem image” on page 39 for a

typical pack/unpack sequence.

psfslabel – label a PSFS filesystem

Synopsis

/opt/hpcfs/tools/psfslabel <device> “<label>”

Description

The psfslabel command adds a label to the specified device.

psfsresume – resume a suspended PSFS

filesystem

Synopsis

/opt/hpcfs/tools/psfsresume <directory_mountpoint>

Description

The psfssuspend and psfsresume utilities affect the specified filesystem

on all servers where it is mounted; however, the utilities should be

executed on only one server in the cluster.
