Hello all, I recently had a power failure and can no longer mount my /home directory. The harddrive has two BTRFS partitions: sda7(/) and sda8(/home). The / partition loads up just fine, but /home does not. I've tried btrfsck as shown below and I've included dmesg pertaining to btrfs. This is on ArchLinux and the software versions are as follows: btrfs-progs-unstable 0.19.20101006-1 linux 3.0
I actually have quite a bit of data on this partition that I would rather not lose. Please help! Thanks, Adam btrfsck /dev/sda8: found 152764059648 bytes used err is 1 total csum bytes: 148756860 total tree bytes: 436686848 total fs tree bytes: 160870400 btree space waste bytes: 110424811 file data blocks allocated: 4925582483456 referenced 114231959552 Btrfs Btrfs v0.19 root 5 inode 738980 errors 400 root 5 inode 771936 errors 400 root 5 inode 771937 errors 400 root 5 inode 771938 errors 400 root 5 inode 771939 errors 400 root 5 inode 771941 errors 400 root 5 inode 771942 errors 400 dmesg |grep btrfs [ 15.148281] btrfs: unlinked 13 orphans [ 27.156006] kernel BUG at fs/btrfs/inode.c:4586!
