I got this today, running 2.6.39-07159-gf23a5e1.
The fs in question is mounted:
/dev/sdXX on /usr/local/portage type btrfs (rw,noatime,compress=zlib)
The BUG_ON() call is from:
if (!BTRFS_I(inode)->orphan_meta_reserved) {
BTRFS_I(inode)->orphan_meta_reserved = 1;
reserve = 1;
}
/* *ELIDED* */
/* grab metadata reservation from transaction handle */
if (reserve) {
ret = btrfs_orphan_reserve_metadata(trans, inode);
BUG_ON(ret);
}
and I cannot umount(8) that fs since this. It claims to be in use.
A du(1) gets stuck but remains interuptable and quits cleanly when
signaled.
The load at the time of the BUG_ON(), for that fs, had significant
file creation, deletion and replacement. It had previously (this
boot) been remotely mounted with nfs, but was not at the time of
the BUG_ON().
