The ctdb-based clustering mode provides a guarantee of data integrity and consistent locking among FileStore nodes. A CIFS share can be served from multiple nodes simultaneously and therefore provides better load balancing.
A CIFS share can be served from multiple virtual IP addresses (VIPs) simultaneously. There will not be any tie up between a VIP and a CIFS share. No redistribution of the CIFS share is required while deleting the VIP. A newly-added VIP can be easily used to serve the CIFS share without any administrator intervention.
