Un-configure CFS cluster and mount point

Summary

I have two hosts

Ø Guest1

Ø Guest3

Configured in VCS and CFS. There is one mount point /cfs configured in cfs cluster “cfs_cluster”. My ./cfscluster status output goest here:

[root@guest1 ~]# /opt/VRTS/bin/cfscluster status

Node : guest1

Cluster Manager : running

CVM state : running

MOUNT POINT SHARED VOLUME DISK GROUP STATUS

/cfs cfsvol cfsdg MOUNTED

Node : guest3

Cluster Manager : running

CVM state : running

MOUNT POINT SHARED VOLUME DISK GROUP STATUS

/cfs cfsvol cfsdg MOUNTED

Steps

1- Find master node in cluster – run following command

a. Vxdctl –c mode

2- Check if cfs mount point is visible in current mounted volumes

a. #df –h

3- Check cluster status by running

a. /opt/VRTSvcs/bin/hastatus -sum

-- SYSTEM STATE

-- System State Frozen

A guest1 RUNNING 0

A guest3 RUNNING 0

-- GROUP STATE

-- Group System Probed AutoDisabled State

B ClusterService guest1 Y N ONLINE

B ClusterService guest3 Y N OFFLINE

4- Check CFS cluster status.

a. /opt/VRTS/bin/cfscluster status #Output is already shared in summary

5- Check current disk and DG configuration by running

a. #vxdisk list

b. #vxprint –hrt

6- Umount the CFS volume

a. /opt/VRTSvxfs/cfs/bin/cfsumount /cfs

Unmounting...

/cfs got successfully unmounted from guest1

/cfs got successfully unmounted from guest3

7- Delete the mount point from CFS cluster configuration

a. /opt/VRTS/bin/cfsmntadm delete /cfs

Mount Point is being removed...

/cfs deleted successfully from cluster-configuration

8- Un-configure the CFS cluster

a. ./cfscluster unconfig
