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).
