hi, anyone knows what will happen if I wrote to a disk on node A, then node A fails, then I move the disk to another node B (new member of the cluster or existing member)...

will I be able to recover this data?

the 3 node cluster has no replicas, only primary shards

It _could_ work (and I have seen it work), but we don't make guarantees that it _will_ work.

So to test this, start a 3 node cluster, through some data at it, kill a node, start a fresh node with path.data pointing in other node data location, check logs?

Any other ideas?

Are there any docs about it? I wasn't able to find anything...

It is not a supported or tested method, which would explain why it is not documented. I would recommend instead running with a replica configured as this would be a lot easier to manage sand less risky. This would also help against corruption due to disk failures, which moving disk does not.

Ok, I'll put it all into consideration…

This is a cluster meant for searching logs, it's ok to lose some logs (I can always reload those using logstash)

Thanks
