Hi!

I got a X server / drm related crash or hard lockup. After I rebooted I
tried to mount the BTRFS on my esata disk. It has big metadata
(mkfs.btrfs -l 32768 -n 32768).


I got:

[… backtrace …]

BTRFS was not mounted. After trying to mount again, I got:

merkaba:~> ps aux | grep " D" | grep -v grep
root      3446  0.0  0.0      0     0 ?        D    20:22   0:00
[btrfs-transacti] root      4666  0.0  0.0  18640  1184 tty1     D+  
20:24   0:00 mount /mnt/amazon-daten

Any hints how to get my disk mounted?

I have a fairly recent backup, but I would prefer when I do not have to
replay it. Its one of my expectations for a file system: be safe on
sudden write interruptions like power loss or crash.

Well, I wanted to have back my disk ASAP. So I just tried that btrfs-zero-
log mantra again.

It worked. Hopefully the backtrace still gives you a clue on what has 
happened. I thought these kind of errors where gone now.

(Yeah, I know its still experimental… no indoctrination requested;-)

Thanks,
