Unexporting a volume and destroying an NFS-Ganesha HA Cluster¶
Here, we’ll see how we can unexport a volume and destroy a high availability cluster.
Step 1:
Create the following configuration file:
[hosts]
dhcp37-102.lab.eng.blr.redhat.com
dhcp37-103.lab.eng.blr.redhat.com
# To un-export the volume:
[nfs-ganesha1]
action=unexport-volume
volname=ganesha
# To destroy the high availability cluster
[nfs-ganesha2]
action=destroy-cluster
cluster-nodes=dhcp37-102.lab.eng.blr.redhat.com,dhcp37-103.lab.eng.blr.redhat.com
‘ganesha’ is the name of our volume.
Step 2:
Run this file using:
$gdeploy -c ganesha_destroy.conf
Here, “ganesha_destroy.con” is the name of our configuration file created in Step 1.
Step 3:
Now, when you run this command on any or all of the nodes in the cluster, you will not see any mounts for nfs-ganesha:
$showmount -e localhost
You have successfully unexported the volume and destroyed the HA cluster.
