I'm running openSUSE 12.3 x86_64 which has an unknown git version, but
reports v0.19.
I'm also supplying the output from git which reports itself as:
v0.20-rc1-253-g7854c8b
The problem is that btrfs-show (git) and btrfs fi show (git) give
/different/ output from each other which is also different

I'm running openSUSE 12.3 on x86_64.
I was running a balance:
btrfs balance -dusage=5 -v /
using the latest btrfs tools code from git (as of this writing)
and got a crash:
[304158.496250] btrfs: found 75 extents

I have a device that is part of a 4-device btrfs "raid1" setup.
I had accidentally jiggled the cable for this device and it started racking
up errors (about 90,000). After fixing the cable (and a scrub), all of
the errors are fixed (woo!), but
the device still shows lots of errors. Is there a way t

I have a 4-disk btrfs filesystem in "raid1" mode.
I'm running openSUSE 12.3, 3.7.10, x86_64.
A few days ago something went wrong and the filesystem re-mounted itself RO.
After reboot, it didn't come up.
After a fair bit of work, I can get the filesystem to mount with "-o
recovery,ro". However, if
Tried to mount with "-o recovery" using 3.8.7. No change. Does
anybody have any suggestions?

I *can* mount this with "-o recovery,ro" but nothing else works.

I had a btrfs filesystem under 3.9.8 that failed /hard/ today. So hard
that the filesystem could not be mounted because there wasn't enough
free space, unless it was mounted read only.
This happened after I ran out of metadata space (is there a way to
increase the amount of metadata storage) while

Using openSUSE 13.1 on x86_64 which - as of this writing - is 3.11.10,
I tried to copy a bunch of files over to a btrfs filesystem (which was

After some time, things ground to a halt and I got out of disk space errors.
