     quotacheck - ufs file system quota consistency checker

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

     quotacheck -a [-fpv]

     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.

     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

     -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 modified.

     See largefile(5) for the description of the behavior of quo-
     tacheck  when  encountering files greater than or equal to 2
     Gbyte ( 2**31 bytes).
