Hi,
For about 3 weeks I've been using btrfs on my desktop machine, using
the snapshot-functionality quite a lot.
Today I ran btrfsck and got about ~10MB of output which looks like:
fs tree 565 refs 125 not found
unresolved ref root 807 dir 813347 index 277 namelen 39 name
snapshot_1368273601_2013-05-11_14:00:01 error 600
unresolved ref root 808 dir 813347 index 277 namelen 39 name
snapshot_1368273601_2013-05-11_14:00:01 error 600
.......
fs tree 566 refs 125 not found
unresolved ref root 807 dir 813347 index 278 namelen 39 name
snapshot_1368274201_2013-05-11_14:10:01 error 600
unresolved ref root 808 dir 813347 index 278 namelen 39 name
snapshot_1368274201_2013-05-11_14:10:01 error 600
......
while the log contained a lot of different values for "fs tree", the
refs which were not found stays fairly constant:
refs: 125, 397, 398, 406, 407, 420
How serious are those issues, should I be worried?
Would it help if I find ways to reproduce this behaviour on a fresh
btrfs filesystem?
Thank you in advance, Clemens

Hi again,
I am able to induce the btrfsck errors I experienced using a synthetic
workload on a fresh filesystem with linux-3.10.0.rc2.
However as filing the bug-report would take quite some time (uploading
512mb trace-files, writing a short read-me, ...) I wonder whether this
is an issue woth of reporting, or maybe just caused by an outdated
version of btrfsck (I am using
btrfs-progs-0.20.rc1.20130308git704a08c-1).
Regards, Clemens

You are running on an unmounted fs right? Also please make sure you are running
the git version
git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git
Thanks,
Josef

Yes, the fs was properly unmounted.

I still get those errors, I'll try to file a bug-report with the
tools/data required to reproduce this issue...
Thanks, Clemens
