Late last night I did an upgrade in 16.04 which include a new version of grub.
This morning I could no longer boot to 17.10 nor 16.04, it would end on a busybox prompt.
Using an external drive with neon I was able to fix the booting on 16.04 by removing the line in /etc/grub.d/40_custom pointing to the 17.10 btrfs partition.
(Next tests are all done from 16.04 that has all the btrfs tools installed)
So far a repair of this 40_custom file fails and now I notice the KDE partition manager is crashing while scanning the disk (/dev/sda).
Re-installation did not help.
(k)df and other utilities do see the drive and dolphin gives access the the btrfs partitions and data.
A search gave me this page with btrfs stuff:
https://btrfs.wiki.kernel.org/index.php/Getting_started
But the first command to scan already fails:
Specifying the partitions gives a different response:
I need more btrfs knowledge...
