Well here are the mount options:

martin@merkaba:~> grep home /proc/mounts
/dev/mapper/merkaba-home /mnt/home-zeit btrfs 
rw,noatime,compress=lzo,ssd,space_cache 0 0
/dev/mapper/merkaba-home /home btrfs rw,noatime,compress=lzo,ssd,space_cache 
0 0

The first one with with subvolid=5, so I can create "hidden" snapshots in 
there. The scrub also hangs if this is not mounted.

Thanks,
