Hello,
On a newly created filesystem with btrfs-progs-git-20111009 and the 3.1.0-rc8
kernel I am getting the following error when doing btrfsck after main OS
installation
fs tree 256 refs 2
unresolved ref root 256 dir 256 index 2 namelen 8 name __active error 600
found 4215058432 bytes used err is 1
total csum bytes: 3962760
total tree bytes: 157192192
total fs tree bytes: 146976768
btree space waste bytes: 45236856
file data blocks allocated: 4123439104
referenced 4056010752
Btrfs v0.19-35-g1b444cd-dirty
256 is the subvolume for /
[root@yukikaze ~]# btrfs subvol list /
ID 256 top level 5 path __active
ID 257 top level 5 path __home
Should I be concerned with this error?
I saw a similar question here
http://comments.gmane.org/gmane.comp.file-systems.btrfs/12455
but no hints were provided for the reason of the error.
Any info is appreciated.
thanks

Don't worry, this is a known bug of btrfsck's refs check, and just btrfsck,
it does no harm to btrfs.
