Hi,
I would focus on the MONs first. If they don't start, your cluster is
not usable. It doesn't look like you use cephadm, but please confirm.
Check if the nodes are running out of disk space, maybe that's why
they don't log anything and fail to start.
Zitat von Amudhan P <amudhan83@xxxxxxxxx>:
Hi,
Recently added one disk in Ceph cluster using "ceph-volume lvm create
--data /dev/sdX" but the new OSD didn't start. After some rest of the other
nodes OSD service also stopped. So, I restarted all nodes in the cluster
now after restart.
MON, MDS, MGR and OSD services are not starting. Could find any new logs
also after restart it is totally silent in all nodes.
Could find some logs in Ceph-volume service.
Error in Ceph-volume logs :-

But I could find "

the path valid and listing folder.
Not sure how to proceed or where to start any idea or suggestion ?
