GlusterFS 9 : GlusterFS + NFS-Ganesha2021/05/08 |
|
Install NFS-Ganesha and integrate with GlusterFS to mount Gluster Volume with NFS protocol.
The supported NFS protocols by NFS-Ganesha are v3, v4.0, v4.1, pNFS. |
|
| [1] | Disable NFS feature in Gluster first. The NFS feature in Gluster is officially deprecated. Also if NFS server is running, stop and disable it, too. |

# OK if [nfs.disable: on] (default setting) [root@node01 ~]# gluster volume get vol_distributed nfs.disable Option Value ------ ----- nfs.disable on # if [nfs.disable: off], turn to disable [root@node01 ~]# gluster volume set vol_distributed nfs.disable on volume set: success # if NFS server is running, disable it [root@node01 ~]# systemctl disable --now nfs-server |
| [2] | Install and Configure NFS-Ganesha on a Node in GlusterFS Cluster. |
