QUOTACHECK(8)						      System Manager's Manual						     QUOTACHECK(8)

NAME
       quotacheck - filesystem quota consistency checker

SYNOPSIS
       quotacheck [ -v ] filesystem ...
       quotacheck [ -v ] -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).

       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.

       -v	      quotacheck reports discrepancies between the calculated and recorded disk quotas.

       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 quotas 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.local 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
       quotas	      at the filesystem root

       /etc/fstab     default filesystems

BUGS
       The quotas file may be named arbitrarily but must reside in the filesystem for which it contains quota information.  Quotacheck	will  give
       the error:

	    %s dev (0x%x) mismatch %s (0x%x)

       if the quotas file is not in the filesystem being checked.  This restriction is enforced by the kernel but may be lifted in the future.
