This reminded me of doing a balance-run on the 2-hdd btrfs-RAID1 in my
desktop machine. Runs now.

The machine runs and boots on btrfs only (as well as my 2 thinkpads), I
know that btrfs still isn't as well tested as extX or XFS, for example
... but I am quite happy so far (doing backups is essential for
everyone, right?)

Regarding the topic of this thread ... I am off-topic here ;-) sorry

-> GPT on a single SSD (containing / and the OS, the hdds hold data),
and systemd ...

I run 2 systems (desktop and one laptop) with 2 distros installed in
parallel, Fedora and Gentoo, and btrfs helps to share storage nicely
here. It even works to share the EFI-boot-partition etc  ... the only
issue is that having multiple kernels for each distro frequently leads
to manually remove one older kernel to be able to add another -> Yes,
that partition was sized too small and isn't so easy to grow right now.
No big problem.

As I mentioned in another btrfs-related thread here a few months ago I
really appreciate the move from partitions/LVM/RAID/filesystems to this
new concept where all these layers are somehow integrated and interacting.

Sorry for OT-ing here, regards, Stefan
