Hello, I have a btrfs volume on a two 1TB disk, and i've been trying to add a new (1.5 TB) to this volume. I've done btrfsctl -a /dev/sdb /mnt/btrfs without trouble, and btrfs-show see the third disk. But I've got segfault when I try to balance the data. And when a try a fsck, he do absolutely nothing. See the commands below (and the dmesg)
So if you have any idea, or want to do any additionnal tests (other than throwing away data that are on theses disks, since, even if i know btrfs is under heavy developpment, id'like to keep some data and haven't the right device right now to do the transfer). Cordially. <r...@oni:/home/alpha> zsh/3 2 # umount /mnt/btrfs umount: /mnt/btrfs: not mounted [mar. 10/01/26 20:07 CET][pts/11][x86_64/linux-gnu/2.6.33-rc5-00247-gc3e6a41][4.3.9] <r...@oni:/home/alpha> zsh/3 3 [1] # btrfsck /dev/sdb failed to read /dev/sr0 bad block 2064048422912 bad block 924702326784 leaf parent key incorrect 2026404634624 bad block 2026404634624 leaf parent key incorrect 2045515939840 bad block 2045515939840 owner ref check failed [924702326784 4096] owner ref check failed [2026404634624 4096] owner ref check failed [2045515939840 4096] owner ref check failed [2064048422912 4096] found 1884638785584 bytes used err is 1 total csum bytes: 1836791604 total tree bytes: 3778641920 total fs tree bytes: 1484914688 btree space waste bytes: 611092845 file data blocks allocated: 1926324310016 referenced 1880273379328 Btrfs v0.19-4-gab8fb4c [mar. 10/01/26 20:10 CET][pts/11][x86_64/linux-gnu/2.6.33-rc5-00247-gc3e6a41][4.3.9] <r...@oni:/home/alpha> zsh/3 4 [1] # btrfsck /dev/sdb failed to read /dev/sr0 bad block 2064048422912 bad block 924702326784 leaf parent key incorrect 2026404634624 bad block 2026404634624 leaf parent key incorrect 2045515939840 bad block 2045515939840 owner ref check failed [924702326784 4096] owner ref check failed [2026404634624 4096] owner ref check failed [2045515939840 4096] owner ref check failed [2064048422912 4096] found 1884638785584 bytes used err is 1 total csum bytes: 1836791604 total tree bytes: 3778641920 total fs tree bytes: 1484914688 btree space waste bytes: 611092845 file data blocks allocated: 1926324310016 referenced 1880273379328 Btrfs v0.19-4-gab8fb4c [mar. 10/01/26 20:20 CET][pts/11][x86_64/linux-gnu/2.6.33-rc5-00247-gc3e6a41][4.3.9] <r...@oni:/home/alpha> zsh/3 5 [1] # mount /mnt/btrfs [mar. 10/01/26 21:38 CET][pts/11][x86_64/linux-gnu/2.6.33-rc5-00247-gc3e6a41][4.3.9] <r...@oni:/home/alpha> zsh/3 6 # btrfs-show failed to read /dev/sr0 Label: none uuid: 3e021a76-954e-4f54-86a0-fa3849e451c2 Total devices 3 FS bytes used 1.71TB devid 3 size 1.36TB used 3.99GB path /dev/sdb devid 2 size 931.51GB used 930.01GB path /dev/sdc devid 1 size 931.51GB used 929.00GB path /dev/sdd Btrfs v0.19-4-gab8fb4c [mar. 10/01/26 21:38 CET][pts/11][x86_64/linux-gnu/2.6.33-rc5-00247-gc3e6a41][4.3.9] <r...@oni:/home/alpha> zsh/3 7 # btrfs-vol -b /mnt/btrfs zsh: segmentation fault btrfs-vol -b /mnt/btrfs [mar. 10/01/26 21:41 CET][pts/11][x86_64/linux-gnu/2.6.33-rc5-00247-gc3e6a41][4.3.9] <r...@oni:/home/alpha> zsh/3 9 [139] # dmesg |grep BUG [ 6417.151192] kernel BUG at fs/btrfs/volumes.c:1746!
