hi,
i have a problem with mounting a btrfspartition. i think it corrupted somehow. btrfsck also didn't work. here is the demesg output, if i try to btrfsck it:

hi,

i used a current stable gentoo with a 2.6.34-r2 gentoo-kernel. the btrfs filesystem is on a lvm, which is on a luks-partition.
i think i corrupted the filesystem with a 2.6.34 tuxonice kernel, witch ran fine without suspend-to-disk, but after suspending i couldn't reboot anymore. this debug is made on a sysrescuecd 1.5.8, after i try to btrfsck it. if i try to mount it, the terminal hangs, but i can switch to another. would it help if i copy some data off the filesystem?

ciao, adi

ok, i have tried the 2.6.35-rc6 kernel, as TiCPU on #btrfs suggested, b= ut i also got an error. i don't think it has something to do with kcryp= t, as i can mount another partition without any problems.

hm, and btw, that dump was made on another pc.

here is a dmesg-dump:

Hi, Adi

Quoted 1 line · Adi

ok, i have tried the 2.6.35-rc6 kernel, as TiCPU on #btrfs suggested, but i also got an error. i don't think it has something to do with kcrypt, as i can mount another partition without any problems.

It seems this problem is the same as the one I have fixed. Could you try to applied the following patches and test again?

hi Miao,

now i get that error (on btrfsck):

parent transid verify failed on 5403553792 wanted 103380 found 103378
btrfsck: disk-io.c:739: open_ctree_fd: Assertion `!(!tree_root->node)' failed.

if i want to mount it, it shows the same error in dmesg, but neither one hangs the terminal, as it did without the patches. do you need more debug? i didn't know how to activate it on gentoo, what flags do i need to do so?
hm, and the last patch didn't show any output on "patch -p1"... is that normal?

bye, adi

I don't know the detailed reproduce steps.Could you tell us the steps just like this?

# mkfs.btrfs /dev/sdaN
# mount /dev/sdaN /mnt
# dd ......
# (suspend-to-disk)
...

It is very useful for our analysis.

Thanks

Hi Miao,

ok, i'll try:

mkfs.ext3 /dev/sdaN
=C2=BBused it as root-file-system quite a while=C2=AB
tune2fs -O extents,uninit_bg,dir_index /dev/sdaN (converted to ext4) =C2=BBused it as root file system quite another while=C2=AB btrfs-convert /dev/sdaN (converted to btrfs)
=C2=BBused it as root filesystem with "-compress" quite another while=C2= =AB
installed tuxonice-patches on kernel
restart -> still works
suspend-to-disk
and from here on the bug appeared

hope, this helps,
Ciao, Adi
