quotacheck - filesystem quota consistency checker
quotacheck [-d] [-g] [-u] [-v] filesystem [...]
quotacheck [-d] [-g] [-l maxparallel] [-u] [-v] -a
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
latter only occurs if an active filesystem is checked). By
user and group quotas are checked.
-a If the -a flag is supplied in place of any filesystem names,
quotacheck will check all the filesystems indicated
to be read-write with disk quotas. By default, only
the types of
quotas listed in /etc/fstab are checked.
-d Enable debugging mode. No actual data will be written on

Limit the number of parallel checks to the number

recorded disk quotas.

are run on the filesystems required, using the pass numbers
in an identical fashion to fsck(8).
Normally quotacheck operates silently.
quotacheck expects each filesystem to be checked to have
named quota.user and quota.group located at the root of the
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
for each user. Thus, the filesystems checked should be quiescent while
quotacheck is running.
