Replace a FabricPool mirror on a MetroCluster configuration

10/14/2021 Contributors

If one of the object stores in a FabricPool mirror is destroyed or becomes permanently unavailable on a MetroCluster configuration, you can make the object store the mirror if it is not the mirror already, remove the damaged object store from FabricPool mirror, and then add a new object store mirror to the FabricPool.

Steps

If the damaged object store is not already the mirror, make the object store the mirror with the storage aggregate object-store modify command.
```
storage aggregate object-store modify -aggregate -aggregate fp_aggr1_A01 -name mcc1_ostore1 -mirror-type mirror
```
Remove the object store mirror from the FabricPool by using the storage aggregate object-store unmirror command.
```
storage aggregate object-store unmirror -aggregate <aggregate name> -name mcc1_ostore1
```
You can force tiering to resume on the primary data store after you remove the mirror data store by using the storage aggregate object-store modify with the -force-tiering-on-metrocluster true option.

The absence of a mirror interferes with the replication requirements of a MetroCluster configuration.
```
storage aggregate object-store modify -aggregate <aggregate name> -name mcc1_ostore1 -force-tiering-on-metrocluster true
```

Create a replacement object store by using the storage aggregate object-store config create command.

storage aggregate object-store config create -object-store-name mcc1_ostore3 -cluster clusterA -provider-type SGWS -server <SGWS-server-1> -container-name <SGWS-bucket-1> -access-key <key> -secret-password <password> -encrypt <true|false> -provider <provider-type> -is-ssl-enabled <true|false> ipspace <IPSpace>

Add the object store mirror to the FabricPool mirror using the storage aggregate object-store mirror command.
```
storage aggregate object-store mirror -aggregate aggr1 -name mcc1_ostore3-mc
```

Display the object store information using the storage aggregate object-store show command.

storage aggregate object-store show -fields mirror-type,is-mirror-degraded

aggregate      object-store-name mirror-type     is-mirror-degraded
-------------- ----------------- ------------- ------------------
aggr1          mcc1_ostore1-mc    primary           -
               mcc1_ostore3-mc    mirror          true

Monitor the mirror resync status using the storage aggregate object-store show-resync-status command.

storage aggregate object-store show-resync-status -aggregate aggr1

                                                  Complete
      Aggregate    Primary        Mirror          Percentage
      ---------    -----------    ----------      ----------
      aggr1        mcc1_ostore1-mc mcc1_ostore3-mc   40%
