gfs2_quota(8)							 gfs2_quota(8)

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 command.

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	 argu‐
	      ment.

       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 speci‐
	      fied 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 speci‐
	      fied  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 mis‐
	      match, it is printed to stdout.  Note: GFS2 quotas are  transac‐
	      tional  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 opera‐
	      tion.

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
