Same thing when starting with CentOS 7.2 media.
This is a NAS product using CentOS 7.2? My only guess

Weird. I was not able to reproduce the problem with CentOS 7.0 doing
the following in virt-manager with two qcow2s

Hello Chris,
That's a bit weird. This is BIOS or UEFI system? On UEFI, the prebaked
grubx64.efi includes btrfs, so insmod isn't strictly needed. But on
BIOS it would be.
it is a Virtual-Box-VM. It is a BIOS system

Hello Hugo,
>> Here I am stuck in a recovery prompt.
By far the simplest and most reliable method of doing this is to
use an initramfs with the command "btrfs dev scan" in it somewhere
before mounting. Most of the major distributions already have an
initramfs set up (as does yours, I see),

Hello,
I would like to go the sensible way :-)
But can you hint me how and where to add the btrfs device scan option to the
initramfs?
If btrfs-progs 4.3.1 is installed already, dracut -f will rebuild the
initramfs and should just drag in current tools which will include
'btrfs device scan'.
Hello,
I am running CentOS from a btrfs root.
This worked fine until I added a device to that pool:
btrfs device add /dev/sda3 /
reboot
This now causes the errors:
BTRFS: failed to read chunk tree on sdb3
BTRFS: open_ctree failed
Here I am stuck in a recovery prompt.
btrfs fi show displays
