gargamel:/var/log# mount /dev/mapper/raid0d2 /mnt/btrfs_space
mount: wrong fs type, bad option, bad superblock on /dev/mapper/raid0d2,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail

which makes it possible to disable automatic parent

Hi,
Subvol A on source side: (A, -)
Send this to A' on target side: (A', A)
