That looks like that LV does not exist or is not activated. What do `pvs`, `vgs`, and `lvs` say? Does /dev/hdd67/data67 exist? If not, does /dev/mapper/hdd67-data67 exist?

That looks like a deliberate, clean shutdown triggered via systemd (as in "systemctl stop ceph-osd@60" or something triggering an equivalent action). Unfortunately there's nothing in the log to suggest what caused this, assuming it wasn't intended/manual. What happens if you just try to start the OSDs again? Maybe check the overall system log with journalctl for hints.
