On Debian I have had the experience that one of the OSD-related systemd unit files was not installed - sorry that I can't recall which one, but the error you describe is the same one I had. The required file was in the source package, but was apparently left off the list of files to be copied into the install package. Once I copied the file over to /lib/systemd/system everything started working again. If I had to guess it was either ceph-volume@.service, or more likely - based on timestamps on my one of my OSD servers, ceph-osd@.service. Hope this helps. -Dave Dave Hall Binghamton University kdhall@binghamton.edu On 7/3/2020 4:58 PM, Alexander E. Patrakov wrote:
Hi,
Just rebooted one of my OSD servers after upgrading Ceph from 14.2.9 to 14.2.10 and it's OSDs won't come up.
I find the following messages on my log:

and my /var/lib/ceph/osd/ceph-6 directory is empty.
I see that on my other servers these /var/lib/ceph/osd/ceph-? directories are tmpfs mounts but I can't understand who is responsible for mounting them as there are no entries for them in /etc/fstab.
How can I fix this osd server? Hi, it is not possible to figure this out based on just the information that you provided. E.g., how was the OSD initially

In any case, the following commands (please run as root) would help debugging:
lsblk lvs -a -o name,lv_tags
