Hi all, on our octopus-latest cluster I accidentally destroyed an up+in OSD with the command line
ceph-volume lvm zap /dev/DEV It executed the dd command and then failed at the lvm commands with "device busy". Problem number one is, that the OSD continued working fine. Hence, there is no indication of a corruption, its a silent corruption. Problem number two - the real one - is, why is ceph-colume not checking if the OSD that device belongs to is still up+in? "ceph osd destroy" does that, for example. I believe to remember that "ceph-volume lvm zap --osd-id" also checks, but I'm not sure. Has this been changed in versions later than octopus? I think it is extremely dangerous to provide a tool that allows the silent corruption of an entire ceph cluster. The corruption is only discovered on restart and then it would be too late (unless there is an in-official recovery procedure somewhere). I would prefer that ceph-volume lvm zap employs the same strict sanity checks as other ceph-commands to avoid accidents. In my case it was a typo, one wrong letter.
