NAME
quotacheck —
filesystem quota
consistency checker
SYNOPSIS
quotacheck |
[-gquv]
filesystem ... |
quotacheck |
[-gquv]
[-l
maxparallel] -a |
DESCRIPTION
quotacheck examines each filesystem, builds a table of current
disk usage, and compares this table against that recorded in the disk quota
file for the filesystem. If any inconsistencies are detected, both the quota
file and the current system copy of the incorrect quotas are updated (the
latter only occurs if an active filesystem is checked). By default both user
and group quotas are checked.
Available options:
-
-
- -a
- If the -a flag is supplied in place of
any filesystem names, quotacheck will check all the
filesystems indicated in /etc/fstab to be read-write
with disk quotas. By default only the types of quotas listed in
/etc/fstab are checked. See also
-l.
-
-
- -g
- Only group quotas listed in /etc/fstab
are to be checked. See also -u.
-
-
- -l
maxparallel
- Limit the number of parallel checks to the number specified
in the following argument. By default, the limit is the number of disks,
running one process per disk. If a smaller limit is given, the disks are
checked round-robin, one file system at a time. This option is only valid
with -a.
-
-
- -q
- quotacheck runs more quickly,
particularly on systems with sparse user id usage, but fails to correct
quotas for users [groups] not in the system user [group] database, and
owning no files on the filesystem, if the quota file incorrectly believes
that they do.
-
-
- -u
- Only user quotas listed in /etc/fstab are
to be checked. See also -g.
-
-
- -v
- quotacheck is more verbose, and reports
corrected discrepancies between the calculated and recorded disk
quotas.
Specifying both
-g and
-u is equivalent to
the default. Parallel passes are run on the filesystems required, using the
pass numbers in
/etc/fstab in an identical fashion to
fsck(8).
Normally
quotacheck operates silently.
quotacheck expects each filesystem to be checked to have a
quota files named
quota.user and
quota.group which are located at the root of the associated
file system. These defaults may be overridden in
/etc/fstab.
If a file is not present,
quotacheck will create it.
quotacheck is normally run at boot time from the
/etc/rc file, see
rc(8), before enabling disk quotas
with
quotaon(8).
quotacheck accesses the raw device in calculating the actual
disk usage for each user. Thus, the filesystems checked should be quiescent
while
quotacheck is running.
If
quotacheck receives a
SIGINFO
signal (see the
status argument for
stty(1)), a line will be written
to the standard error output indicating the name of the device currently being
checked and progress information.
FILES
- quota.user
- at the filesystem root with user quotas
