|
[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 stop nfs-server [root@node01 ~]# systemctl disable nfs-server |
[2] | Install and Configure NFS-Ganesha on a Node in GlusterFS Cluster. |
