NAME    [Toc]    [Back]

     quotacheck - filesystem quota consistency checker

SYNOPSIS    [Toc]    [Back]

     quotacheck [-d] [-g] [-u] [-v] filesystem [...]
     quotacheck [-d] [-g] [-l maxparallel] [-u] [-v] -a

DESCRIPTION    [Toc]    [Back]

     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.

     -d      Enable debugging mode.  No actual data will be written on

     -g       Only  group  quotas  listed in /etc/fstab are to be

     -l maxparallel
             Limit the number of parallel checks  to  the  number
             specified in the argument (see fsck(8)).

     -u       Only  user  quotas  listed  in /etc/fstab are to be

     -v      quotacheck reports 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
quota files
     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
disk usage
     for each user.  Thus, the filesystems checked should be quiescent while
     quotacheck is running.

FILES    [Toc]    [Back]

     quota.user   at the filesystem root with user quotas
     quota.group  at the filesystem root with group quotas
     /etc/fstab   default filesystems

HISTORY    [Toc]    [Back]

OpenBSD      3.6                           June      5,      1993
