@Natanox #openSUSE #Tumbleweed use btrfs since years as default. In the beginning it was a little bit tricky with the snapshot size. But since about more than 5 years it is pretty stable as root file-system on my desktop as well on my server.
Benfit:
* Raid 0/1 Support out of the box
* Increasing / Decreasing on a running system
* snapshot with Rallback on boot if a update fails (on the most distros)
* Some nice features which are not present in my head ;-)

@ulfi Do you know a way to make lsblk and other tools display it properly? πŸ˜‰

@ulfi Oh, since I already asked something: In case of RAID1 on two disks, can both have the same UUID so in case of catastrophic failure the device still boots despite one of them (which could've been the "root") being dead?

That would be really neat.

@Natanox
lsblk works fine on all my installations.

According the UUID shouldn't be two with the same one. But if you install on one btrfs, you can later add the second as RAID1. How the second will be used in case the main was defect depends on your boot (EFI/MBR and grub) setup

@Natanox I don't try that, but it is supposed but you boot the raid, no the device. @ulfi

@ulfi @Natanox
* you can add/remove any btrfs device to any btrfs filesystem on a running system
