Ok, our one bad block is in the extent allocation tree. This is going
to be the very hardest thing to fix.
Until I finish off the code to rebuild parts of the extent allocation
tree, I think your best bet is to copy the files off.
The big question is, what happened to make this error? Can you describe
your setup in more detail?
I created this btrfs filesystem on an arch linux system (amd64, quad
core) with kernel 2.3.38.1. it is on top of a md raid 5.
[root@linuxserver ~]# cat /proc/mdstat
Personalities : [raid6] [raid5] [raid4]
md0 : active raid5 sde1[3] sdc1[1] sda1[0] sdf1[4]
5860535808 blocks super 1.2 level 5, 512k chunk, algorithm 2
[4/4] [UUUU]
the raid was grown from 3 devices to 4, and then btrfs was grown to max
size. mount options were clear_cache,compress-force.
I was investigating a performance issue that i had, because over the
network i could only write to the filesystem at about 32mb/sec.
when writing btrfs-delalloc- cpu usage was at 100%.
While investigating i disabled compression, enabled space_cache and
tried zlib compression, and various combinations, while copying large
files back and forth using samba.
BTW I tried to change some mount options using mount -o remount but
although the new options were printed on dmesg i think that they were
not enabled.
I got the first error when i was copying some files and at the same time
created a directory over samba. After a while i upgraded to 2.6.38.5 but
nothing seems to have changed.
I really dont think there is a hardware error here, but to be safe I am
now running a check on the raid

attached you can find the whole dmesg log. I can trigger the error again
if more logs are needed
Yes, I'll send you a patch to get rid of the printk for the transid

Will you be able to compile/test it?
