How to start back a down node

[subh14]

Hi
If a master/tserver stays down for 30min/ or 1hr or more than an hour, whats the best practice to start back that node. I am using YSQL. Should I just start back that server?

Yes, you can start the server again.

Hi Dorian
once a Tserver or Master is down for a longer period, to maintain replication factor of 3, rest of the Tservers takes care of it?
And once that Tserver comes backup, wouldn’t it create a conflict between tablets?

Yes. See how replication works: Replication in DocDB | YugabyteDB Docs

No. It will see that those tablet-replicas are behind compared to the rest of the cluster.
