Correction, there is a patch up there now.

Several SATA controllers support hot-swapping in Linux, but you're still at the
whim of replication.

Good
Good point. Advice without details can be tough.
Additional notes: make sure you have three replicas and the blocks
are replicated. :)

Much quicker, but less safe: data might become inaccessible between boots if
you simultaneously lose another node. Probably not an issue at 3 replicas, but
definitely an issue at 2.

Hello,
One of our nodes has a bad hard disk which needs to be replaced. I'm
planning on doing the following:
1) Decommission the node
2) Replace the disk
3) Bring the node back into the cluster
Is there a quicker/better way to address this? Please advise.
thanks,
M
