NAME
       quotacheck -- file system quota consistency checker

SYNOPSIS
       quotacheck [-guv] [-c 32	| 64] [-l maxrun] -a
       quotacheck [-guv] [-c 32	| 64] filesystem ...

DESCRIPTION
       The  quotacheck	utility	 examines  each	file system, builds a table of
       current disk usage, and compares	this table against  that  recorded  in
       the  disk  quota	 file for the file system.  If any inconsistencies are
       detected, both the quota	file and the current system copy of the	incor-
       rect quotas are updated (the latter only	occurs if an active file  sys-
       tem is checked).	 By default both user and group	quotas are checked.

       The following options are available:

       -a      If  supplied in place of	any file system	names, quotacheck will
	       check all the file systems indicated in /etc/fstab to be	 read-
	       write  with  disk  quotas.  By default only the types of	quotas
	       listed in /etc/fstab are	checked.

       -c 32 | 64
	       Before performing its checks, quotacheck	will convert the quota
	       file to the specified word size.	 A conversion size  of	64  is
	       given  to  request conversion to	the new	64-bit quota file for-
	       mat.  A conversion size of 32 is	given  to  request  conversion
	       back  to	 the old 32-bit	quota file format.  The	original quota
	       file is left unchanged and moved	aside with an  underscore  and
	       its  format  size  plus	a  .orig  extension added to its name.
	       Thus, the original 32-bit quota.user quota  file	 converted  to
	       the   64-bit   format   quota   file   will   be	  renamed   to
	       quota.user_32.orig.

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

       -l maxrun
	       Specifies the maximum number  of	 concurrent  file  systems  to
	       check  in parallel.  If this option is omitted, or if maxrun is
	       zero, parallel passes are run as	per fsck(8).  This  option  is
	       deprecated and parallel passes are always run as	per fsck(8).

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

       -v      Report  discrepancies  between the calculated and recorded disk
	       quotas and other	additional diagnostic messages.

       Specifying both -g and -u  is  equivalent  to  the  default.   Parallel
       passes  are run on the file systems required, using the pass numbers in
       /etc/fstab in an	identical fashion to fsck(8).

       Normally, quotacheck operates silently.

       The quotacheck utility expects each file	system to be checked to	have a
       quota files named quota.user and	quota.group which are 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.
       These files should be edited with the edquota(8)	utility.

       The  quotacheck	utility	 is normally run at boot time from the /etc/rc
       file.  The rc startup procedure is controlled by	the /etc/rc.conf vari-
       able check_quotas.  Note	that to	enable this functionality  in  /etc/rc
       you  also  need	to  enable  startup quota procedures with the variable
       enable_quotas in	/etc/rc.conf.  The kernel  must	 also  be  built  with
       options QUOTA.

       The  quotacheck	utility	accesses the raw device	in calculating the ac-
       tual disk usage for each	user.  Thus, the file systems  checked	should
       be quiescent while quotacheck is	running.

FILES
       quota.user   at the file	system root with user quotas
       quota.group  at the file	system root with group quotas
       /etc/fstab   default file systems

HISTORY
       The quotacheck utility appeared in 4.2BSD.

BUGS
       The quota system	will ignore UIDs or GIDs that would be	negative  when
       evaluated  as  a	signed value.  Typically those types of	ids can	appear
       in the file system from NFS mounts or archive files from	other  operat-
       ing systems.  Extremely large UIDs or GIDs will cause quotacheck	to run
       for  an	unreasonable  amount  of time and also produce extremely large
       quota data files.
