--disable-fzbm

Disable the FZBM feature on the specified filesystem.

--enable-quotas

Build the necessary quota infrastructure on the specified filesystem. The

psfsck utility then examines the existing files and stores current

allocations for each user and group owning a file on the filesystem.

--disable-quotas

Disable quotas on the specified filesystem and free the associated blocks.

--set-udq <size>[T|G|M|K]

Set the default quota for users on the specified filesystem. The optional

modifiers specify that the size is in terabytes (T), gigabytes (G), megabytes

(M), or kilobytes (K). If a modifier is not specified, the size will be

calculated in bytes. (The default is rounded down to the nearest filesystem

block.)

--set-gdq <size>[T|G|M|K]

Set the default quota for groups on the specified filesystem. The modifiers

are the same as the set-udq option. (The default is rounded down to the

nearest filesystem block.)

psfsdebug – get PSFS filesystem image

Synopsis

/opt/polyserve/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.
