One more IMPORTANT note. This might happen due to the fact that a disk was
missing (disk failure) afte the reboot.
fstab and mountpoint are working with UUIDs so they match but the journal
block device:
osd journal = /dev/sde1
didn't match anymore - as the numbers got renumber due to the failed disk.
Is there a way to use some kind of UUIDs here too for journal?
You should be able to use /dev/disk/by-uuid/* instead. That should give you
a stable view of the filesystems.
I often map partitions to something in /dev/disk/by-partlabel and use
those in my ceph.conf files. that way disks can be remapped behind the
scenes and the ceph configuration doesn't have to change even if disks
get replaced.
