group Group: limit:LimitSize warn:WarnSize value:Value
The
LimitSize
,
WarnSize
, and
Value
numbers (values) are in units of megabytes by default.
Adding the
-k
,
-s
, or
-b
flags to the command line change the units to kilobytes, sectors, or
file-system blocks, respectively.
User
A user name or ID to which the data is associated.
Group
A group name or ID to which the data is associated.
LimitSize
The hard limit set for the user or group. This value is zero if no limit has been set.
Value
The actual amount of disk space used by the user or group.
Comments
When displaying quota information, the
gfs_quota
command does not resolve UIDs and GIDs
into names if the
-n
option is added to the command line.
Space allocated to GFS's hidden files can be left out of displayed values for the root UID and
GID by adding the
-d
option to the command line. This is useful when trying to match the
numbers from
gfs_quota
with the results of a
du
command.
Examples
This example displays quota information for all users and groups that have a limit set or are
using any disk space on file system
/gfs
.
gfs_quota list -f /gfs
This example displays quota information in sectors for group
users
on file system
/gfs
.
gfs_quota get -g users -f /gfs -s
4.3. Synchronizing Quotas
GFS stores all quota information in its own internal file on disk. A GFS node does not update
this quota file for every file-system write; rather, it updates the quota file once every 60 seconds.
This is necessary to avoid contention among nodes writing to the quota file, which would cause
