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 incor‐
       rect 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 com‐
		bination 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 partic‐
		ular  file system. quotacheck normally reports only those quo‐
		tas modified.

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).

FILES
