See the shell outputs below: root@sto-3-3:~# file /var/lib/ceph/osd/ceph-388/journal /var/lib/ceph/osd/ceph-388/journal: broken symbolic link to /dev/disk/by-partuuid/d2ace848-7e2d-4395-a195-a4428631b333 root@sto-3-3:~# blkid /dev/nvme0n1p11 /dev/nvme0n1p11: PARTLABEL="ceph journal" PARTUUID="d2ace848-7e2d-4395-a195-a4428631b333" root@sto-3-3:~# udevadm info /dev/nvme0n1p11 P: /devices/pci0000:00/0000:00:02.0/0000:02:00.0/nvme/nvme0/nvme0n1/nvme0n1p11 N: nvme0n1p11 E: DEVNAME=/dev/nvme0n1p11 E: DEVPATH=/devices/pci0000:00/0000:00:02.0/0000:02:00.0/nvme/nvme0/nvme0n1/nvme0n1p11 E: DEVTYPE=partition E: ID_PART_TABLE_TYPE=gpt E: ID_PART_TABLE_UUID=8c11f541-fdc1-4299-923b-dc57d8a38619 E: MAJOR=259 E: MINOR=11 E: SUBSYSTEM=block E: TAGS=:systemd: E: USEC_INITIALIZED=7070417 root@sto-3-3:~# grep nvme0n1p11 /var/log/syslog Jan 4 09:17:20 sto-3-3 systemd-udevd[106928]: incorrect nilfs2 checksum on /dev/nvme0n1p11 ...so the bogus nilfs2 checksum failure is causing udev to not create the ID_PART_ENTRY_UUID and similar entries (and hence the /dev/disk /by-partuuid link) and is breaking my ceph setup. I think this is related to this upstream issue: https://github.com/karelzak/util-linux/issues/361 ...this is quite a serious bug, as it's causing unrelated software (ceph) to break.
