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.

NAME

       quotacheck - ufs file system quota consistency checker

SYNOPSIS

       quotacheck [-fp] [-v] filesystem...

       quotacheck -a [-fpv]

DESCRIPTION

       quotacheck  examines  each  mounted  ufs file system, builds a table of current disk usage, and compares this table against the information
       stored in the file system's disk quota file. If any inconsistencies are detected, both the quota file and the current system  copy  of  the
       incorrect quotas are updated.

       filesystem is either a file system mount point or the block device  on which the file system resides.

       quotacheck  expects  each file system to be checked to have a quota file named quotas in the root directory. If none is present, quotacheck
       will not check the file system.

       quotacheck accesses the character special device in calculating the actual disk usage for each  user.  Thus,  the  file	systems  that  are
       checked should be quiescent while quotacheck is running.

OPTIONS

       The following options are supported:

       -a    Check  the  file  systems which /etc/mnttab indicates are ufs file systems.  These file systems must be read-write mounted  with disk
	     quotas enabled, and have an rq entry in the mntopts field in /etc/vfstab.

       -f    Force check on file systems with logging enabled. Use in combination with the -p option.

       -p    Check quotas of file systems in parallel. For file systems with logging enabled, no check is performed unless the -f option  is  also
	     specified.

       -v    Indicate  the  calculated	disk quotas for each user on a particular file system. quotacheck normally reports only those quotas modi-
	     fied.

USAGE

       See largefile(5) for the description of the behavior of quotacheck when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
