Hi!
Since upgrading from 2.6.35+bits to 2.6.38 and then more recently to 3.0,
our big btrfs backup box with 20 * 3 TB AOE-attached btrfs volumes
started showing more CPU usage and backups were no longer completing in a
day. I tried Linus HEAD from yesterday merged with btrfs for-linus (same

Perhaps as a further clue as to what is going on, on this same backup box
after all of the rsyncs are finished/killed and a good amount of time has
passed (no cleaner processes running in the background or anything),
sync is still consistently takes ~4 minutes to run, and pushes out a
lot to disk

the actual blocks of a snap _are_ the changes, that's why SnapMirror

Hello!
We seem to have done something to our backup volumes while switching
between 2.6.33.2 and 2.6.35.4 which is now causing this crash while
booting either kernel and mounting one of the volumes. Crash from
3.6.35.4 plus Li Zefan's free-space-cache.c patches. extent-tree.c
is untouched, but
Sorry, I meant to change that subject. :)

What does btrfsck say? Does the problem go away in 2.6.33?
Will try 2.6.33 again tomorrow. btrfsck runs for about 44 seconds and
then outputs as copied below.

I was running this while the fs was mounted, which is probably not what
was expected, but here's a crash report anyway. :)

I've been wondering if it would possible/useful to make a btrfs mode

write anywhere already, it could just write sequentially always.
The write process would have to be changed to read a blob, throw away

Hi!
We have some btrfs rsync-snapshot backup servers which have been running
since about mid-2009, with a pretty good record so far. We've been
following the development kernels and hitting some bugs here an there,
but we still haven't managed to lose anything yet. The main problems we
have ran

We were having a problem with I/O to one btrfs volume on a 3.8-rc6 box
hanging completely with no CPU usage or I/O (according to iostat, iotop).
Here is after a reboot to 3.8-rc7 with lockdep enabled:
