Hi Chris,

Thanks for your detailed answer.

Here is what the command returns :

[root@x220 ~]# btrfs-find-root /dev/mapper/home
Super think's the tree root is at 115230801920, chunk root 131072
Went past the fs size, exiting[root@x220 ~]#

I just tried with latest btrfs-progs (from git), it returns exactly the
same.

The btrfs partition is on top of dm-crypt, could it be a problem?
