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: 4991 Jul 3 17:24:03 osdserver1-df ceph-osd[1272]: 2020-07-03 17:24:03.036 7fcc497f1c00 -1 auth: unable to find a keyring on /var/lib/ceph/osd/ceph-6/keyring: (2) No such file or directory 4992 Jul 3 17:24:03 osdserver1-df ceph-osd[1272]: 2020-07-03 17:24:03.036 7fcc497f1c00 -1 AuthRegistry(0x55e2ff810140) no keyring found at /var/lib/ceph/osd/ceph-6/keyring, disabling cephx 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?
