HP Clustered Gateway Device Management Software manual Psfsdebug get Psfs filesystem image

Chapter 1: Matrix Server Commands 38

--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>[TGMK]

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>[TGMK]

Set the default quota for groups on the specified filesystem. The modifiers are the same as the set-udqoption. (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 -poption compresses the data, while the -Poption 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.

-pis 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 -pcompression algorithm will be affected by the corruption and the unpacked metadata will not be identical to the original.
