Well done Jolla for dropping Btrfs. I've been using Btrfs on the desktop for the last few years and have experienced corruption on at least 3 separate occasions. I've tested my disks and they are still in working order, but each time the fsck utility was unable to repair the errors and the filesystem had to be rebuilt from scratch. Good luck to SUSE with their enterprise Linux but I won't touch Btrfs again with a barge pole. ZFS on the other hand is awesome but I've yet to try the Linux implementation.
