After upgrade, Veritas Data Deduplication configuration fails as the virtual IP association with deduplication is being used by CIFS

In case of CTDB CIFS share where the IPs are not explicitly mentioned, any free virtual IP is assigned during configuration. As part of upgrade, Veritas Data Deduplication is unconfigured and the virtual IP used for deduplication is released to the network pool. When the CIFS server comes online, it may use the released IP and the virtual IP is stamped in the vip_service_map.yml file against a CIFS entry. When Veritas Data Deduplication is reconfigured after upgrade, the virtual IP previously associated with deduplication is already part of yml. This leads to an error and a message is displayed that the virtual IP is already being used for CIFS.

Workaround:

After the upgrade is complete, if you find that the virtual IP previously associated with Veritas Data Deduplication is getting used by the CIFS server, run the following commands:

  • network> ip addr del <dedupe_ip>
  • network> ip addr add <dedupe_ip> netmask virtual

This forces the CIFS server to pick up another free virtual IP from the network pool, and then deduplication can be configured with its original virtual IP.
