Description

Issue description:

We found data corruption in one of table, while performing cluster syncing.

 

Corrective actions:

We have performed 'nodetool repair' to sync up the nodes, post removing the corrupted table. There were two, out of four node, in the cluster was down before we triggered the 'repair'. However, during the repair all the servers were live and active.

 

We are using Cassandra 3.11.1.

Appreciate your help to pinpoint the issue, and let me know reasons to data corruption in table and how we can prevent it?
