[Gluster-users] orphaned snapshots

[Sebastian Neustein]

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:
|[2023-08-08 19:34:03.667109 +0000] E [MSGID: 106115]

Even worse: I followed read hat gluster snapshot trouble guide 
<https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/troubleshooting_snapshots> 
and deleted one of those directories defining a snapshot. Now I receive 
this on the cli:

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
