Hello,
I am using a raid1 under debian Jessie, because I need to decrease the
likelyhood of unavailability of the system.
Unfortunately I found, that when removing one of the drives, the system
will not boot up. Instead initramfs will show up and tell me that the
root volume could not be mounted.
I read here:
https://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg31265.html
that adding rootflags=degraded.
Furthermore I see that this is not yet default -at least in Ubuntu-
https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1229456?comments=all
But that it should work by modifying /etc/grub.d/10_linux:
https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1229456/comments/3
GRUB_CMDLINE_LINUX="rootflags=subvol=${rootsubvol},degraded
${GRUB_CMDLINE_LINUX}"
when doing that and running grub-mkconfig and update-grub, I still get
no entry with with "degraded" in /etc/grub.cfg.
Can someone tell me, how to achieve this? I've been seaching for very
long now and I am surprised, that I don't find any answer.
Greetings,
Hendrik
