Running DSS v7 in HA cluster mode on 2 nodes for years now. Some time ago one of the server nodes experience some hardware crash.
After restarting the failed, the cluster status now displays:
* node A: cluster running - degraded
* node B: cluster status - stopped

my 2 iscsi volumes are running as active on node A.

How can I safely fix my cluster?

Node B is outdated for several weeks now and I feel uncertain to fix the cluster.
It displayed the following prompt:

After starting it I got the node running in degraded mode and on the other node it's stopped.

Goal is to get my cluster back and keeping all data on node A (the degraded one). So that one should replicate its data back to node B.

Is following assumption correct?
- I need to cause some downtime by stopping the cluster completely
- trigger manual replication of the data volumes from node A (both volumes as source) to node B (both volumes as destination)
- then change the replication direction again so that my second volume has node B as source and node A as destination
- restart the cluster

It looks to me that when node B suddenly crashed, DSS lost its state of being source or destination upon the reboot.
