Still, even with raid1 for metadata and raid5 for data, the kernel still shouts at you about it being EXPERIMENTAL every time you mount such a filesystem. I understand that it's best to err on the side of caution, but that notice does a good job of persisting the idea that btrfs isn't ready for prime-time use. I use btrfs on most of my Linux systems now (though only one with raid5), except for backup disks and backups volumes: those I intend to keep on ext4 indefinitely.
