btrfs and linux-rt

btrfs and linux-rt

[Daniel Kasak]

Greetings.

I've just re-installed Linux on my laptop, and to my horror ... linux-rt is
not compatible with btrfs. I have all my partitions using btrfs now. When
Linux boots, it hangs when mounting the root partition. I've searched
around a little, and found others reporting the same. Are there any plans
to sort out this incompatibility?

Thanks :)

Dan

I remember some people complained about btrfs. I then bootet a kvm
machine with btrfs as rootfs and it worked fine… Are you using some
"special" btrfs features or is this just a plain install?

Okay. Among other things I manged to install fc21 on btrfs and it
booted (well systemd complain about missing things and did not want to
continue but I got a shell and could login which means btrfs got
mounted).

Interesting.

Nah I wasn't doing anything special with btrfs. I'll try again with a
3.18 kernel and see if it's magically resolved :)

I've tested with 3.18.9-rt5, and I'm happy to report that this kernel
works fine for me :)
