NAME
      quotacheck - file system quota consistency checker

SYNOPSIS
      quotacheck [-v] [-p] filesystem . . .
      quotacheck [-apv]

DESCRIPTION
      quotacheck examines each file system, builds a table of current disk
      usage, and compares this table against that stored in the disk quota file
      for the file system.  If any inconsistencies are detected, both the quota
      file and the current system copy of the incorrect quotas are updated (the
      latter only occurs if an active file system is checked).

      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
      ignore the file system.

      quotacheck accesses the character special device in calculating the
      actual disk usage for each user.  Thus, the file systems checked should
      be quiescent while quotacheck is running.

      The options are:

      -v    Indicate the calculated disk quotas for each user on a particular
            file system.  quotacheck normally reports only those quotas
            modified.

      -a    Check the file systems indicated in /etc/mnttab to be read-write
            with disk quotas.  Only those file systems that have "rq" in the
            mntopts field of the /etc/vfstab file are checked.

      -p    Run parallel passes on the required file systems.

FILES
