The btrfs raid has one subvolume; the raid and the subvolume were mounted via /etc/fstab. The RAID worked extremely well until I did a zypper update perhaps two weeks ago. Immediately following the update, I needed to reboot the workstation. I shutdown kdm using init 3 from the system console and rebooted the machine with shutdown -r now from the system console. The workstation hung during the reboot and I had to hard power it off in order to continue with the reboot. After the power on, the btrfs raid appeard as normal, but the kernel occasionally threw oops. I did not realize at the time that the opps were related to the btrfs raid. After several days of workstation usage, the btrfs raid became inaccessible. I tried to ummount and remount it; at the mount command there was a kernel panic. I removed the mount -t btrfs command from /etc/fstab and the workstation boots and operates normally. I would like to attempt to recover the btrfs raid. Here are my actions to do so: 1. Issue command "btrfs-show" Label: HD103SJ_btrfs uuid: 2ff6e89d-b790-425b-837b-475d1504be69 Total devices 2 FS bytes used 733.80GB devid 1 size 931.51GB used 369.53GB path /dev/sdd devid 2 size 931.51GB used 369.51GB path /dev/sde Btrfs Btrfs v0.19 2. Issue command "btrfsck /dev/sde" btrfsck: disk-io.c:416: find_and_setup_root: Assertion `!(!root->node)' failed. I am trying to determine the check that the Assertion wants to make. That is, I would like to know what the btrfs module is trying to do that is causing it to fail. After spending time and posting the question to the linux-btrfs mailing list, I have concluded that the assertion is from Novell's code. Reproducible: Always Steps to Reproduce: 1.btrfsck 2. 3. Actual Results: btrfsck: disk-io.c:416: find_and_setup_root: Assertion `!(!root->node)' failed.
