Title: Boot fails with encyprted BTRFS RAID1 array - open ctree failed Status in The Linux Mint Distribution: New Status in upstart package in Ubuntu: New Bug description: I have recently installed Linux Mint 17.1 into a system with three drives - 1 SSD containing the / partition (btrfs format), and 2 identical HDD's containing /home in an encrypted BTRFS RAID1 array. The system will not boot without manual intervention, using either the recommended 3.13.0-37 kernel or the most up to date 3.16.0-31 kernel. At about the same time that I am prompted to enter my password to unlock the drive, I am prompted that a mount has failed. If I press M to enter manual recovery I see the emergency shell. Then all I have to do is exit (Ctrl+D) to continue booting and everything works normally. It appears that a similar (maybe the same) bug was reported on ArchWiki: https://wiki.archlinux.org/index.php/Btrfs#BTRFS:_open_ctree_failed I also experienced this bug on OpenSUSE 13.2 and filed a bug report there: https://bugzilla.opensuse.org/show_bug.cgi?id=912170 On a possibly related note, I am getting TWO password prompts even though both encrypted volumes use the same password. On OpenSUSE only one password was required. My understanding is that as soon as you suppy one password it is supposed to be tried on each volume in /etc/crypttab. I will now try the fix that worked for me on OpenSUSE (see bug report) copy /usr/lib/udev/rules.d/64-btrfs.rules into /etc/udev/rules.d/64-btrfs.rules and replace the following two lines ENV{DM_NAME}=="", IMPORT{builtin}="btrfs ready $devnode" ENV{DM_NAME}=="?*", IMPORT{builtin}="btrfs ready /dev/mapper/$env{DM_NAME}" with single one IMPORT{builtin}="btrfs ready $devnode" and report back what happens.
