UUID strings in the file /etc/fstab refer to devices. you can retrieve UUID
using command blkid, for instance:
# blkid /dev/sda1
/dev/sda1: UUID=1bcb1cbb-abd2-4cfa-bf89-1726ea6cd2fa TYPE=xfs

How did you get the UUIDs without mounting the osds?
Thanks

Hi，Jesus
I encountered similar problem.
1. shut down one of nodes， but all osds can't reactive on the node after reboot.
2. run service ceph restart manually, got the same error message:
[root@storage4 ~]# /etc/init.d/ceph start
=== osd.15 ===
