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  calcu-
     lating  the  actual disk usage for each user. Thus, the file
     systems that are checked should be  quiescent  while  quota-
     check 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
