Phase 2 — Cluster A Fails And Client Requests Fail Over To Backup Cluster B

If source cluster A stops responding because of an unexpected failure (hardware, disk, and so on), you must:

1.Log on to backup cluster B.

2.Delete the existing replication policy for all replication target volumes.

When deleting the replication policy from the destination cluster B — FluidFS replication manager tries to contact source cluster A, which fails. The volume on destination cluster B must have its configuration restored using Cluster Management Restore NAS Volume Configuration.

When deleting the replication policy from the source cluster A — You are given an option to apply the source volumes configuration to the destination volume. If you do not remember to select this, or it fails, the configuration of the source volume from cluster A can be restored onto the destination volume on cluster B using Cluster Management Restore NAS Volume Configuration.

3.Confirm replication policy deletion on backup cluster B, and that the source volume configuration from cluster A is applied.

Currently the following volume configurations can be restored:

NFS exports

CIFS shares

Quota rules

Snapshot schedule

NAS volume alerting, security style and related parameters

NAS volume name

NAS volume size

This transforms target volumes (B1, B2, .. Bn) to standalone volumes. Repeat this procedure to bring all target volumes in cluster B to standalone volumes with volume configuration applied from cluster A.

4.From the NAS Manager web interface, restore the NAS system configuration from cluster A.

This restores cluster B configuration to cluster A settings. Currently the following cluster system configuration can be restored:

Protocols configuration

Users and Groups

User mappings

Monitoring configuration

Time configuration

Antivirus hosts
