Couchbase EBS volumes setup for a 3 Node cluster

So, we want to have a 3 Node Couchbase Cluster and my question is :

  1. Should the EBS volume be same - all 3 nodes attached to the same EBS volume - or different - each node gets its own EBS volume
  2. If different, should the EBS snapshots/backups be taken for each node separately and whenever there is a failover, the failed nodes’ EBS volume be connected to the new node after rebalancing?

No, they should all be attached to different volumes as each node manages its own data.

We would recommend using ‘cbbackupmgr’ to take backups rather than relying on EBS snapshots because of the challenges when re-attaching.
