Hi,
Is there any command-line history available to get at least some sort
of history of events?
Are all MONs down or has one survived?
Could he have tried to change IP addresses or something? There's an
old blog post [0] explaining how to clean up. And here's some more
reading [1] how to modify a monmap in a cephadm managed cluster.
I assume none of the ceph commands work, can you confirm?

Zitat von RIT Computer Science House <csh@xxxxxxx>:
Hello,
Our cluster has become unresponsive after a teammate's work on the cluster.
We are currently unable to get the full story on what he did to fully
understand what is going on, and the only error we are able to see in any
of the logs is the following:
2024-08-20T03:12:34.183+0000 7f3670246b80 -1 unable to read magic from mon
data
Any help would be greatly appreciated!
I can provide any information necessary to help debugging.
Thanks,
Tyler
