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'.
Yes, 4.3.1 is installed and even in the recovery-mode (i.e. if boot
fails) btrfs reports version 4.3.1.
Also, in this recovery mode, btrfs dev scan is working. Furthermore, I
can mount the drive in this recovery mode (which I *suspect* is the
initramfs).
My understanding is/was, that it is not sufficient that btrfs dev scan
is available, but also its execution must be triggered. Is that right?
Like I said above, just install the distribution's own
btrfs-progs/btrfs-tools package, and it should do the right thing. You
may have to tell the distribution to rebuild the initramfs
I have run dracut -f. It does not solve the issue.

Yes, it is Rockstor (CentOS 7.2 based) installed in the way you mention.
