[root@node01 ~]# gluster volume quota vol_distributed enable volume quota : success gluster volume info Volume Name: vol_distributed Type: Distribute Volume ID: 725fb28f-5678-4c2d-86b7-ab8c0165c323 Status: Started Snapshot Count: 0 Number of Bricks: 2 Transport-type: tcp Bricks: Brick1: node01:/glusterfs/distributed Brick2: node02:/glusterfs/distributed Options Reconfigured: features.quota-deem-statfs: on features.inode-quota: on features.quota: on performance.parallel-readdir: on performance.readdir-ahead: on performance.nl-cache-timeout: 600 performance.nl-cache: on network.inode-lru-limit: 200000 performance.md-cache-timeout: 600 performance.cache-invalidation: on performance.stat-prefetch: on performance.cache-samba-metadata: on features.cache-invalidation-timeout: 600 features.cache-invalidation: on performance.write-behind: off user.smb: enable storage.fips-mode-rchecksum: on transport.address-family: inet nfs.disable: on # to disable, set like follows [root@node01 ~]# gluster volume quota vol_distributed disable |
| [2] | Set quota to the entire volume. |
|
# for example, set 1GB quota to the entire [vol_distributed] volume # gluster volume quota [volume name] limit-usage [path of target directory] [hard_limit] [root@node01 ~]# gluster volume quota vol_distributed limit-usage / 1GB volume quota : success gluster volume quota vol_distributed list

| [3] | Set quota to a directory on a volume. |
|
# for example, set 1GB quota to [/dir01] directory on [vol_distributed] volume [root@node01 ~]# gluster volume quota vol_distributed limit-usage /dir01 1GB volume quota : success gluster volume quota vol_distributed list

| [4] | Set specific soft limit to a quota setting. |
|
# for example, set 1GB quota to [/dir01] directory on [vol_distributed] volume and set 70% soft limit # gluster volume quota [volume name] limit-usage [path of target directory] [hard_limit] [soft_limit]
[root@node01 ~]#
[root@node01 ~]# gluster volume quota vol_distributed limit-usage /dir01 1GB 70 volume quota : success gluster volume quota vol_distributed list

| [5] | To delete quota, run command like follows. |
