Subject: raid0 corruption, how to restore?
Date: Tue, 02 Nov 2010 04:14:01 -0400 [thread overview]
Message-ID: <4CCFC849.6040407@warpmail.net> (raw)
I have two disks that I formatted as btrfs RAID0 on opensuse 11.3. The
raid worked well several days until there was a power surge. The system
successfully rebooted and the btrfs raid reappeared, but the kernel
occasionally threw oops. That was my first experience with oops. After
two days, the btrfs raid failed to mount via fstab and when I manually
tried to mount it, there was a kernel panic.
I would like to recover the data from the btrfs raid. If I issue the
command: btrfs-show, I receive:
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
Obviously the RAID and the filesystems are still there. I then try to
fsck the drives:
btrfsck /dev/sde
btrfsck: disk-io.c:416: find_and_setup_root: Assertion `!(!root->node)'
failed.
I do not understand the error message that is provided. Can someone
shed a little light on that message?
Thank you.
