BTW. after this I must restart my PC, and after restart, my system doesn't
boot anymore :-) (some more btrfs oops).
So I must use btrfs check --repair /dev/sdaX.
Sigh and of course I can't reproduce myself, even with importing a
huge database into derby. So you are just mounting with -o
compress=lzo? What about the mkfs, are you using raid or anything?
Are you on a ssd? Also when this happens is there any output above
the --- [ cut here ] ---? There should be something about length and
such. Thanks,
I was able to reproduce on with 3.8 using Ubuntu 13.04 running in KVM
using the commands exactly as given, but it only after stopping and
starting the server again.
I use the cloud image from here, boot of an Ubuntu CD-ROM ISO to change
from ext4 to btrfs, then installed openjdk.
http://cloud-images.ubuntu.com/raring/current/raring-server-cloudimg-amd64-disk1.img
I could make my image available for download later if you need it, in a
pre-failure state. Let me know.
