@(#)quotacheck.8 8.1 (Berkeley) 6/5/93
.Dd $Mdocdate: May 31 2007 $ .Dt QUOTACHECK 8 .Os .Sh NAME .Nm quotacheck .Nd filesystem quota consistency checker .Sh SYNOPSIS .Nm quotacheck .Op Fl adguv .Op Fl l Ar maxparallel .Ar filesystem ... .Sh DESCRIPTION .Nm 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.
p Available options: l -tag -width Ds t Fl a If the .Fl a flag is supplied in place of any filesystem names, .Nm will check all the filesystems indicated in
a /etc/fstab to be read-write with disk quotas. By default, only the types of quotas listed in
a /etc/fstab are checked. t Fl d Enable debugging mode. No actual data will be written on disk(s). t Fl g Only group quotas listed in
a /etc/fstab are to be checked. t Fl l Ar maxparallel Limit the number of parallel checks to the number .Ar maxparallel specified in the argument (see .Xr fsck 8 ) . t Fl u Only user quotas listed in
a /etc/fstab are to be checked. t Fl v .Nm reports discrepancies between the calculated and recorded disk quotas. .El
p Specifying both .Fl g and .Fl u is equivalent to the default. Parallel passes are run on the filesystems required, using the pass numbers in
a /etc/fstab in an identical fashion to .Xr fsck 8 .
p Normally .Nm operates silently.
p .Nm expects each filesystem to be checked to have quota files named
a quota.user and
a quota.group located at the root of the associated file system. These defaults may be overridden in
a /etc/fstab . If a file is not present, .Nm will create it.
p .Nm is normally run at boot time from the
q see Xr rc 8 before enabling disk quotas with .Xr quotaon 8 .
p .Nm accesses the raw device in calculating the actual disk usage for each user. Thus, the filesystems checked should be quiescent while .Nm is running. .Sh FILES l -tag -width quota.group -compact t Pa quota.user at the filesystem root with user quotas t Pa quota.group at the filesystem root with group quotas t Pa /etc/fstab default filesystems .El .Sh SEE ALSO .Xr quota 1 , .Xr quotactl 2 , .Xr fstab 5 , .Xr edquota 8 , .Xr fsck 8 , .Xr quotaon 8 , .Xr repquota 8 .Sh HISTORY The .Nm command appeared in x 4.2 .
