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 combina‐
             tion 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.


FILES
       /etc/mnttab    Mounted file systems


       /etc/vfstab    List of default parameters for each file system
