3.7.0 HP StorageWorks HP Scalable NAS File Serving Software command reference guide HP Scalable NAS for Linux (AG513-96003, October 2009)
Tell psfsck to place information about any corruption it finds into the specified
logfile instead of sending it to stderr.
--no-modify, -n
Check the filesystem in read-only mode. Prevents psfsck from replaying the
journal and/or fixing any corruption. If errors are found, it is strongly recommen-
ded that you run psfsck again in check mode, without the --no-modify op-
tion, before running with the --rebuild-tree option.
The -no-modify option cannot be specified in addition to --rebuild-tree
or --rebuild-sb.
-a
Cause psfsck to assume that it was called by psfsck -A and to return, even
if the filesystem does not seem to be unmounted cleanly.
-y
Cause psfsck to answer “yes” to all questions.
The psfsck utility also provides options to enable or disable Full Zone Bit Maps
(FZBMs), to enable or disable quotas, to specify the default quota for users and
groups, and to enable the small files performance feature on filesystems created
before the 3.7.0 release. These options are:
--enable-fzbm
Enable the FZBM feature on the specified filesystem. This on-disk filesystem format
reduces the amount of data that the filesystem needs to read when allocating a
block. It is particularly useful for speeding up allocation times on large, relatively
full filesystems. For details about FZBM, see the article “Using the FZBM On-Disk
Filesystem Format” on www.hp.com.
--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.)
