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 incon-
       sistencies  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.
