Liking btrfs a lot.  This weekend I started upgrading to a 2x2T drive setup for media from a single 1T drive.  A bit of a pain, but I learned a bit.  I also found out that my current drive was probably in worse shape than I thought.

- Upgrading Seagate drive firmware using grub2 chained bootable iso was a no-go.  Will just have to live with it.

- Learned about GPT partitions and 4k sectors and gdisk.  Nice to see that drive partitioning has almost progressed beyond MBR and 4 partitions.

- Added the new drive using btrfs device add

- Converted to RAID1 using btrfs balance

- Almost freaked out when my old drive hit a patch of bad sectors.

- Deleted some unused junk on the drive.  Rebooted

- Started the balance again, success!  (btrfs also remapped a bunch of bad metadata using it's built-in redundancy! btrfs read error corrected:)

Next up, removing the old drive and adding in the 2nd 2T drive, followed by moving the root and home partitions to a new SSD.  Anyone using btrfs on their boot partition?
