http://bugzilla.opensuse.org/show_bug.cgi?id=912170 Bug ID: 912170 Summary: Boot fails with BTRFS RAID1 array as /home - open ctree failed Classification: openSUSE Product: openSUSE Distribution Version: 13.2 Hardware: 64bit OS: openSUSE 13.2 Status: NEW Severity: Major Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: RyanSKingsbury@alumni.utexas.net QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I recently did a clean install of OpenSUSE 13.2 into a system with three drives - 1 SSD containing the / partition (btrfs format with default subvolumes), and 2 identical HDD's containing /home in an encrypted BTRFS RAID1 array. Initially, I was using only one of the HDD's as /home (still encrypted BTRFS). Once I added the second drive and started the RAID1 mirroring, my system will no longer boot without manual intervention. I get dropped into "emergency mode", but then all I have to do is exit (Ctrl+D) to continue booting and everything works normally. The last entry in the system log before Emergency Mode is invoked is: Code: BTRFS: open_ctree failed It appears that a similar (maybe the same) bug was reported on ArchWiki: https://wiki.archlinux.org/index.php/Btrfs#BTRFS:_open_ctree_failed But the solution refers to mkinitcpio rather than dracut that OpenSUSE uses, so I'm unsure how to apply it to my system.
