I had these configured and working in a mergerfs disk pool, ran into an issue and ended up needing to reinstall Ubuntu server. Since then, I can manually mount the drives in my ThunderBay 8 but the syste doesn't boot after adding them to my fstab.
e.g.
# sudo mount /dev/disk/by-uuid/5c3245c8-29a4-416f-b1b4-b49841b81ce2 /mnt/disk1
# lsblk -f
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
sdb
└─sdb1 ext4 1.0 5c3245c8-29a4-416f-b1b4-b49841b81ce2 370.7G 92% /mnt/disk1
Add to /etc/ftsab:
UUID="5c3245c8-29a4-416f-b1b4-b49841b81ce2" /mnt/disk1 ext4 defaults 0 0
# sudo mount -a
# reboot
System will only reboot in emergency mode and suggests looking at journalctl -xb

Not sure if it's related, but the Thunderbay has a DisplayPort out and I've seen the "PPM init failed (-110)" error a couple times. Was wondering if maybe it's the driver for that, but searching online doesn't seem to return any results. I only see the PPM error when the fstab entries are active.
Currently I'm at a loss, any help is much appreciated!
