Hi Mohamed, are all mons down, or do you still have at least one that is running? AFAIK: the mons save their DB on the normal OS disks, and not within the ceph cluster. So if all mons are dead, which mean the disks which contained the mon data are unrecoverable dead, you might need to bootstrap a new cluster and add the OSDs to the new cluster. This will likely include tinkering with cephx authentication, so you don't wipe the old OSD data. If you still have at least ONE mon alive, you can shut it down, and remove all the other mons from the monmap and start it again. You CAN have clusters with only one mon. Or is did your host just lost the boot disk and you just need to bring it up somehow? losing 4x2 NVME disks at the same time, sounds a bit strange. Am Do., 2.
