NAME
     quotacheck - EFS filesystem quota consistency checker

SYNOPSIS
     /usr/etc/quotacheck [ -v ] [ -p ] filesystem ...
     /usr/etc/quotacheck [ -v ] [ -p ] -a
     /usr/etc/quotacheck [ -v ] -n nusers filesystem ...
     /usr/etc/quotacheck [ -v ] -n nusers -a

DESCRIPTION
     quotacheck examines local EFS filesystems, builds a table of current disk
     usage, and compares this table against that stored in the disk quota file
     for the filesystem.  If any inconsistencies are detected, both the quotas
     file and the current system copy of the incorrect quotas are updated (the
     latter only occurs if quotas has been enabled for the filesystem).  The
     filesystem has to be mounted for quotacheck to be able to operate on it.
     quotacheck ignores XFS filesystems since the XFS quota system is
     journalled and therefore inherently consistent.

     If the -a flag is supplied in place of any filesystem names, quotacheck
     checks all the local filesystems indicated in /etc/fstab to be read-write
     with disk quotas.

     Normally quotacheck operates silently.  If the -v option is supplied,
     quotacheck indicates the disk quotas for each user whose quota
     information was modified.

     If the -p flag is supplied then parallel passes are run on the
     filesystems required, using the pass numbers in /etc/fstab in an
     identical fashion to fsck(1M).

     quotacheck expects each filesystem to be checked to have a quota file
     with the name quotas in the root directory.  If none is present,
     quotacheck ignores the filesystem.

     The quotas file has an index followed by the users' quota information.
     If while adding users with the help of the edquota(1M) command, there is
     no more space left in the index, the superuser can increase the index
     size with the -n option to permit the addition of more users to the
     quotas file.  nusers is the new number of users for whom sufficient index
     size should be allocated.  The default index size allows quotas for 2048
     users.  It is not possible to shrink the index size.  It is advisable to
     remount the filesystem after using this option.

     quotacheck is normally run at boot time from the /etc/rc2.d directory,
     see rc2(1M).

     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.


EXAMPLES
          quotacheck -v -n 3000 /usr

     Increases the quotas file index size to support 3000 users (up from the
     default of 2048) for the /usr filesystem.

FILES
