Comment about stability
Troubleshooting is now outdated
Would be great of some early adopters would modernize this section now that the stable release of btrfs-progs has hit [testing]. As the warning says, the package now includes the btrfsfsck which can fix problems on the filesystem!

Convert Ext3/4 to Btrfs
- It's because of Step #5: Installing btrfs-progs. This is based off of the old install mediums, which had local versions of programs, unless the remote repositories were enabled like in step #2. Since the new install mediums are remote-only (however they might have some filesystem tools on them), the entire section needs updating. Klink-a-dink-dink (talk) 01:06, 24 November 2012 (UTC)
RAID-1 or RAID-5?
"3 1TB disks in an md based raid1 yields a /dev/md0 with 1TB free space and the ability to safely loose 2 disks without losing data. 3 1TB disks in a btrfs volume with data=raid1 will allow the storage of approximately 1.5TB of data before reporting full. Only 1 disk can safely be lost without losing data."
That sounds more like some kind of weird, inefficient RAID-5 arrangement than RAID-1. I don't know btrfs enough to say it's wrong, but I know RAID-1 enough to question it?
btrfs with fsck hook and fstab pass
Apparently one does not need to have a btrfs partition fscked on boot, so there should be a '0' for 'pass' in the fstab for any btrfs partion. I had relatively slow boot ups with a pass of '1' (btrfs was root)
the genfstab script puts a '1' in for 'pass' by default
