Hi, Customer wants to test a recovery scenario like this:
Cassandra node´s data resides in a mounted volume (not local disk). Node´s host (VM) fails, but data remains OK in the device. Host is recovered using a two hours ago VM snapshot (NOT a Cassandra´s snapshot) of the original host, same Cassandra config files, same host IP, same filesystems are mounted (including node´s data directory), all the same.
We think that for recovery on this scenario, we only need start node up on the recovered host and all must work well after a while, node on recovered host will receive pending hints, additionally we can do a nodetool repair on the node to force sync of pending mutations (primary range only?) after start it.
Are we right ?? Or are we missing something ?
