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. <br>

<span class="yiv5705540302c-mrkdwn__br"></span>How can I
delete these orphaned snapshots? Trying the normal way

Even worse: I followed <a rel="nofollow noopener noreferrer" target="_blank" href="https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/troubleshooting_snapshots" class="yiv5705540302c-link">read hat gluster snapshot

defining a snapshot. Now I receive this on the cli:<br>

<br>
What are my options? <br>
- is there an easy way to remove all those snapshots?<br>
- or would it be easier to remove and rejoin the node to
the gluster cluster?<br>
<br>
Thank you for any help!<br>
