So much for btrfs...

On the initial kernel I used for install, I couldn't do a rebalance of the data (kernel oops)...

A new kernel wouldn't boot claiming fsck errors. Turned out to be a malformed udevadm install.

And to top it off, X stopped working.

I reformatted as ext3, fixed the udevadm, and reinstalled the mesa, drm, and X packages, and all works fine.

I'm not sure if the second and third problems had anything to do with btrfs, and I've seen no other signs of corruption. But given that I'm always running bleeding edge kernels, even the oops is disheartening.

Seems like a good idea, but I'll wait before putting it on my root again (or on my NAS)...

btrfs root!

My desktop now has btrfs as a root filesystem. I largely followed this guide. I used a lucid (daily build) live cd to get the job done. I didn't reinstall, so I had to resize partitions to get a separate /boot (parted doesn't do this anymore, but gparted does). My kernel is a custom kernel with btrfs as a module, so that was good. But the update-initramfs doesn't remake initrds for kernels not installed via package (ya ya, I should use a package), so one has to do that specially. Also, the root device as specified in grub's config needs to change for the new UUID. With those caveats, the guide worked perfectly.

Here are the bonnie numbers:

                             btrfs 
Sequential Output (Char)       238
Sequential Output (Block)    48884
Sequential Output (Rewrite)  31956
Sequential Input (Char)       4596
Sequential Input (Block)     89337
Random Seeks                   114

Again, the sequential output may or may not make sense, but it is consistent with the previous number. The sequential input number is way too high, as my disk shouldn't be able of reading more than 75MB/sec (so says hdparm). I'm starting to lose faith in bonnie...

I tried to rebalance, but I got an oops... So that's not working for now.

I'll play with this for a while before I consider putting it on my NAS. :)
