Chapter 1: Matrix Server Commands 37

--rebuild-sb

Rebuild the superblock.

--rebuild-quotas

Repair any errors in the quota metadata and recalculate user and group

quota allocations.

--interactive, -i

Stop psfsck after each pass is completed.

--quiet, -q

Prevent psfsck from reflecting its progress.

--logfile filename, -l logfilename

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

recommended that you run psfsck again in check mode, without the

--no-modify option, 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, and to specify the default quota

for users and groups. 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 PolyServe Knowledge Base article “Using the FZBM

On-Disk Filesystem Format.”
