Hello Nitan, 1. Can sstable corruption in application tables cause schema mismatch? >
I would say it should not. I could imagine in the case that the corrupted table hits some 'system' keyspace sstable. If not I don' see how corrupted data can impact the schema on the node. > 2. Do we need to disable repair while adding storage while Cassandra is > down? > I think you don't have to, but that it's a good idea. Repairs would fail as soon/long as you have a node down that should be involved (I think there is an option to change that behaviour now). Anyway, stopping repair and restarting it when all nodes are probably allows you a better understanding/control of what's going on. Also, it reduces the load in time of troubles or maintenance, when the cluster is somewhat weaker.
