--- Begin Message ---Package: btrfs-tools Version: 0.19+20120328-7 Severity: critical I've marked this as critical as more people are likely to use btrfs with wheezy, and it results in filesystems not coming up at boot, consequently it is a system-wide issue and not just a package issue. It does not involve data loss. Apparently the btrfs dev scan command must be invoked before a btrfs RAID1 filesystem can be mounted. btrfs-tools has some support for this in /lib/udev/rules.d/60-btrfs.rules However, in my case, my RAID1 is made up of two LVM logical volumes, mkfs.btrfs -m raid1 -d raid1 /dev/mapper/vg00-btrfsvol0_[01] and the udev script never seems to be called. When I try to mount the volume after a reboot: # mount /dev/mapper/vg00-btrfsvol0_0 /mnt/btrfs0 mount: wrong fs type, bad option, bad superblock on /dev/mapper/vg00-btrfsvol0_0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so I checked dmesg: [17216.145092] device fsid c959d4a5-0713-4685-b572-8a679ec37e20 devid 1 transid 34 /dev/mapper/vg00-btrfsvol0_0 [17216.145639] btrfs: disk space caching is enabled [17216.146987] btrfs: failed to read the system array on dm-100 [17216.147556] btrfs: open_ctree failed The feedback from the btrfs community is that a) `btrfs dev scan' should run from an init script b) may need the "Device mapper uevents" option in the kernel (CONFIG_DM_UEVENT) to trigger the udev rule when you enable your VG(s) http://comments.gmane.org/gmane.comp.file-systems.btrfs/19271
