GlusterFS 11 : GlusterFS + NFS-Ganesha2023/03/31

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.
For example, Configure NFS Export setting to a Gluster Volume [vol_distributed] like an example of the link here.
[1] Install and Configure NFS-Ganesha on a Node in GlusterFS Cluster.
[root@node01 ~]#
dnf -y install centos-release-nfs-ganesha4
[root@node01 ~]#
sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-NFS-Ganesha-4.repo
[root@node01 ~]#
dnf --enablerepo=centos-nfs-ganesha-4 -y install nfs-ganesha-gluster
[root@node01 ~]#
mv /etc/ganesha/ganesha.conf /etc/ganesha/ganesha.conf.org

[root@node01 ~]#
vi /etc/ganesha/ganesha.conf
# create new

    Path = "/vol_distributed";
    FSAL {
    	# any name

    SecType = "sys";
    # default log level
    Default_Log_Level = WARN;

# if NFS is running, disable it

[root@node01 ~]#
systemctl disable --now nfs-server
[root@node01 ~]#
systemctl enable --now nfs-ganesha
# verify Export list

[root@node01 ~]#
showmount -e localhost

Export list for localhost:
/vfs_distributed (everyone)
[2] If Firewalld is running, allow NFS service.
[root@node01 ~]#
firewall-cmd --add-service=nfs

[root@node01 ~]#
firewall-cmd --runtime-to-permanent

[3] Verify NFS mounting on a Client Host.
[root@client ~]#
dnf -y install nfs-utils
# specify Pseudo path set on [Pseudo=***] in ganesha.conf

[root@client ~]#
mount -t nfs4 node01.srv.world:/vfs_distributed /mnt

[root@client ~]#
df -hT
