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 introduced a new linked list format for the quotas in the quota file. This list format allows for faster list, check and init opera- tions. 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 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 lim- its 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 gfs2_quota(8)

QUOTAON(8) System Manager's Manual QUOTAON(8) NAME
quotaon, quotaoff - turn filesystem quotas on and off SYNOPSIS
/sbin/quotaon [ -vugfp ] [ -F format-name ] filesystem... /sbin/quotaon [ -avugfp ] [ -F format-name ] /sbin/quotaoff [ -vugp ] [ -x state ] filesystem... /sbin/quotaoff [ -avugp ] DESCRIPTION
quotaon quotaon announces to the system that disk quotas should be enabled on one or more filesystems. The filesystem quota files must be present in the root directory of the specified filesystem and be named either aquota.user (for version 2 user quota), quota.user (for version 1 user quota), aquota.group (for version 2 group quota), or quota.group (for version 1 group quota). XFS filesystems are a special case - XFS considers quota information as filesystem metadata and uses journaling to provide a higher level guarantee of consistency. There are two components to the XFS disk quota system: accounting and limit enforcement. XFS filesystems require that quota accounting be turned on at mount time. It is possible to enable and disable limit enforcement on an XFS filesystem after quota accounting is already turned on. The default is to turn on both accounting and enforcement. The XFS quota implementation does not maintain quota information in user-visible files, but rather stores this information internally. quotaoff quotaoff announces to the system that the specified filesystems should have any disk quotas turned off. OPTIONS
quotaon -F, --format=format-name Report quota for specified format (ie. don't perform format autodetection). Possible format names are: vfsold (version 1 quota), vfsv0 (version 2 quota), xfs (quota on XFS filesystem) -a, --all All automatically mounted (no noauto option) non-NFS filesystems in /etc/fstab with quotas will have their quotas turned on. This is normally used at boot time to enable quotas. -v, --verbose Display a message for each filesystem where quotas are turned on. -u, --user Manipulate user quotas. This is the default. -g, --group Manipulate group quotas. -p, --print-state Instead of turning quotas on just print state of quotas (ie. whether. quota is on or off) -f, --off Make quotaon behave like being called as quotaoff. quotaoff -F, --format=format-name Report quota for specified format (ie. don't perform format autodetection). Possible format names are: vfsold (version 1 quota), vfsv0 (version 2 quota), xfs (quota on XFS filesystem) -a, --all Force all filesystems in /etc/fstab to have their quotas disabled. -v, --verbose Display a message for each filesystem affected. -u, --user Manipulate user quotas. This is the default. -g, --group Manipulate group quotas. -p, --print-state Instead of turning quotas off just print state of quotas (ie. whether. quota is on or off) -x, --xfs-command delete Free up the space used to hold quota information (maintained internally) within XFS. This option is only applicable to XFS, and is silently ignored for other filesystem types. It can only be used on a filesystem with quota previously turned off. -x, --xfs-command enforce Switch on/off limit enforcement for XFS filesystems (perform quota accounting only). This option is only applicable to XFS, and is silently ignored for other filesystem types. NOTES ON XFS FILESYSTEMS
To enable quotas on an XFS filesystem, use mount(8) or /etc/fstab quota option to enable both accounting and limit enforcement. quotaon utility cannot be used for this purpose. Turning on quotas on an XFS root filesystem requires the quota mount options be passed into the kernel at boot time through the Linux root- flags boot option. To turn off quota limit enforcement on any XFS filesystem, first make sure that quota accounting and enforcement are both turned on using repquota -v filesystem. Then, use quotaoff -v filesystem to disable limit enforcement. This may be done while the filesystem is mounted. Turning on quota limit enforcement on an XFS filesystem is achieved using quotaon -v filesystem. This may be done while the filesystem is mounted. FILES
