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.

OPTIONS
     -v   Indicates the calculated disk quotas for each user on a particu-
          lar file system. quotacheck normally reports only those quotas
          modified.

     -a   Checks 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   Runs parallel passes on the required file systems.

FILES
     /etc/mnttab
          mounted file systems

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