Upgrade from Access Appliance version 7.4.2.400 to 8.0 fails if CIFS CTBD mode is configured

If CIFS CTBD clustering mode is configured on the appliance (with security = ads) and you perform an upgrade from Access Appliance version, the upgrade fails as the CTDB port does not get added correctly. (IA-40498)

Workaround:

After rollback, stop CTDB. Change the security to user and perform the upgrade again. After upgrade, configure AD and start the CIFS server.

Steps to perform before upgrade:

cifs> server stop
cifs> set security user
cifs> server start
cifs> server stop

Steps to perform after upgrade:

network> ad set
network> ad enable
cifs> server start
