SOLVED GlusterFS cluster, remove virtual IP after trying SMB cluster mode

[Urbaman]

Hi,

I tryied to set up an SMB cluster, now trying to get back to single SMB.
How can I remove the virtual IP added in the process?

Thank you.

Sure! To undo the cluster and go back to single SMB mode, you can do the following:

REVERTING TO NON-CLUSTER MODE on FIRST node:

(Get SMB share and remove clustered share)
# midclt call sharing.smb.query (Get the ‘id’ of the share)
# midclt call sharing.smb.delete 2 (replace ‘2’ with the id of share)
# midclt call service.stop cifs
# midclt call gluster.volume.stop '{"name": "testvol1"}'
# midclt call gluster.volume.delete testvol1 -job
# midclt call ctdb.shared.volume.delete -job
# midclt call service.stop glusterd
# midclt call service.update glusterd '{"enable": false}'
# midclt call smb.reset_smb_ha_mode
# midclt call service.start cifs

REVERTING TO NON-CLUSTER MODE on OTHER nodes:
# midclt call service.stop cifs
# midclt call service.stop glusterd
# midclt call service.update glusterd '{"enable": false}'
# midclt call smb.reset_smb_ha_mode
# midclt call service.start cifs

After doing this and rebooting, you should see those VIPs gone.

Hi,

First command gives me

Code:

[]

Second command gives me

Code:

false

Should I continue?

I still have the IP in there after a reboot.

Thank you

Ok, I went through all of the commands even if some of them gave me errors, and the virtual IP disappeared.

Thank you very much,
