I've (mostly) successfully split my Debian 8 root filesystem into a
/boot partition (still on my original disk) and a
/ partition (using LVM on a second disk).
The system boots fine, but the initramfs (at least I assume it is that) is complaining that it can't check the root filesystem:
fsck error 2 (No such file or directory) while executing fsck.ext3 for /dev/mapper/SSDVG-RootVol fsck exited with status code 8
There is then a successful
fsck of the same filesystem from (I think) systemd.
As far as I can tell, all files in
/usr/share/initramfs-tools are identical to a system originally built as LVM, which does not have this issue.
Is the problem that my initramfs is not loading the LVM support early enough, or that my new root filesystem is somehow not being identified correctly? (I see it is looking for
fsck.ext3, where other logs I've seen online suggest it may usually use
Any advice on where to look to diagnose what is going on appreciated - the Debian grub2 / initramfs behaviour with LVM appears to be rather lightly documented!
