I received the message: btrfs: unlinked 34 orphans
Just out of couriosity: what does it mean ?
Ooh, ooh! I think I know this one :)

Hi Josef,
Btrfs doesn't have the ability to punch holes yet, so make sure we return
EOPNOTSUPP if we try to use hole punching through fallocate. This support can

Hallo, linux-btrfs,
does btrfs accept the (ext2/ext3) option user_xattr? Samba needs
something in that way, but
mount -o user_xattrr btrfs-partition mountpoint
doesn't work.
Viele Gruesse!

Every time btrfs updates the roots is a new generation. Some data

You need to run it as root (via sudo or whatever). On the other hand,
it probably doesn't work like you think it does, and you probably
don't want to defrag anyway :p
btrfs fi defrag takes a file or folder, and defrags just that file or

I am not on the list, so please include me in any replies.
We seem to have found a bug, but I'm not sure if it is a known issue.
We made this FS with an older version of btrfs-utils.
We are running on a debian sid system. The FS was created with
btrfs-tools version 0.19+20100601-3 on 2.6.32.
Hi All:
I found the project ideas about NFS support in btrfs wiki. But, I
have long time to disconnect to the btrfs mail list. Can you give me
the process of the support? Thanks!!
