NAME
       gfs2_quota - Manipulate GFS2 disk quotas


SYNOPSIS
       gfs2_quota        <list|sync|get|limit|warn|check|init|reset>
       [OPTION]...


DESCRIPTION
       gfs2_quota is used to examine and change quota  values  in  a
       GFS2  filesystem.   This  command  has  a number of different
       actions.

       GFS2(5.1) introduced a new linked list format for the  quotas
       in  the quota file.  This list format allows for faster list,
       check and init operations. Older  GFS2  quota  files  may  be
       migrated to this newer format using the gfs2_quota reset com‐
       mand.


ACTIONS
       list   List the contents of the quota file.   Only  IDs  that
              have  a  non-zero hard limit, warn limit, or value are
              printed.

       sync   Sync any local quota changes to the quota file.

       get    Get the current data for the ID specified by the -u or
              -g argument.

       limit  Set the current hard limit for the ID specified by the
              -u or -g argument to the value  specified  by  the  -l
              argument  on the specified filesystem.  The filesystem
              won't let the user or group use more  than  this  much
              space.   A  value  of zero here means that no limit is
              enforced.

       warn   Set the current warn limit for the ID specified by the
              -u  or  -g  argument  to the value specified by the -l
              argument on the specified filesystem.  The  filesystem
              will  start complaining to the user or group when more
              than this much space is used.  A value  of  zero  here
              means that the user won't ever be warned.

       check  Scan  a filesystem and make sure that what's out there
              on the disk matches what's in the quota file.  This is
              only  accurate  if the filesystem is idle when this is
              running.  If there is a mismatch,  it  is  printed  to
              stdout.   Note:  GFS2  quotas  are transactional and a
              quota check is not needed every time there is a system
              crash.

       init   Scan  a  filesystem and initialize the quota file with
              the values obtained from  the  scan.   The  filesystem
              should be idle when this is run.  You should only need
              to do this if you upgrade a pre-quota GFS2  filesystem
              (pre-GFS2 5.1).

       reset  The  reset  operation will truncate the quota file and
              all quota information (values, limits, warnings)  will
              be  lost.   All quota limits and warnings will have to
              be reassigned after this operation.


OPTIONS
       -b The units for disk space are filesystem blocks.

       -f Directory
              Specifies which filesystem to perform the action on.

       -g GID Specifies the group ID for get, limit,  or  warn.   It
              can  be  either the group name from the group file, or
              the GID number.

       -h     Print  out  a  help   message   describing   available
              options, then exit.

       -k     The units for disk space are kilobytes.

       -l Size
              Specifies the new value for the limit or warn actions.
              The value is assumed to be in the units  specified  by
              the   -m,  -k,  -s,  -b  arguments.   The  default  is
              megabytes.

       -m     The units for disk space are megabytes.  This  is  the
              default.

       -n     Don't try to resolve UIDs and GIDs into user and group
              names.

       -s     The  units  for  disk  space  are  sectors   (512-byte
              blocks).

       -u UID Specifies the user ID for get, limit, or warn.  It can
              be either the username from the password file, or  the
              UID number.

       -V     Print program version information, then exit.


EXAMPLE
       To  set the hard limit for user "nobody" to 1048576 kilobytes
       on filesystem /gfs20

       gfs2_quota limit -l 1048576 -k -u nobody -f /gfs20
