Thank you for your reply!

I will set up an test environment and see what will happen.

I’ve never had such situation and I don’t recall someone sharing something similar.

Most probably it’s easier to remove the node from the TSP and re-add it.
Of course , test the case in VMs just to validate that it’s possible to add a mode to a cluster with snapshots.

I have a vague feeling that you will need to delete all snapshots.

Hi

Due to an outage of one node, after bringing it up again, the node has some orphaned snapshosts, which are already deleted on the other nodes.

How can I delete these orphaned snapshots? Trying the normal way produceses these errors:

Even worse: I followed read hat gluster snapshot trouble guide and deleted one of those directories defining a snapshot. Now I receive this on the cli:
run-gluster-snaps-e4dcd4166538414c849fa91b0b3934d7-brick6-brick[297342]: [2023-08-09 08:59:41.107243 +0000] M [MSGID: 113075] [posix-helpers.c:2161:posix_health_check_thread_proc] 0-e4dcd4166538414c849fa91b0b3934d7-posix: health-check failed, going down

What are my options?
- is there an easy way to remove all those snapshots?
- or would it be easier to remove and rejoin the node to the gluster cluster?

Thank you for any help!

Seb
