comment Move root filesystem on a logical volume to a different disk
I thought about that, but I want to remake the filesystem from scratch to match the block size. mkfs.ext4 -O extent -b 4096 -E stride=128,stripe-width=128 /dev/mapper/ssd-debian

Updated grub.cfg with UUID and /dev/mapper for new root, rebooted. Failed to dracut. Posted mount above.

Right, still broken. grub2-mkconfig output is still pointing at lv00 (old hdd root fs), not lvroot (new ssd)

comment Move root filesystem on a logical volume to a different disk
My fstab is fine, I think. See above. The issue is that grub.cfg is still pointing to the old root fs and causing all kinds of havoc. and grub2-install isn't picking up the new root fs on the ssd. The current setup causes errors, the old root fs mounts ro, stopping x/gdm, I remount to rw and x/gdm starts.

grub2. ran grub2-install /dev/sda. My boot-flagged partition is on sda (the hdd). ssd is /dev/sdb.

Exactly. I managed to do it by following [link]void.gr/kargig/blog/2012/01/11/… but I can't seem to get grub to go for the root fs on the ssd instead of the old one on the hdd. /boot is a regular old logical partition.
