Hi,
I tried to balance my home folder. The disk spins and after an hour it
hasn't completed. This is a 300 GB home directory about half full. I
know balance takes while, but how long should it take? This is a 7200
rpm disk on a dual 2 ghz processor laptop running Linux Mint 11 and
btrfs 0.19. It has an ext2 /boot, a btrfs / and btrfs /home partitions.
The btrfs partitions have compression enabled.

Balance currently rewrites everything, and does it in a
not-terribly-efficient way. It's probably done by now (8 hours since
your message), which isn't unusual. There's some improvements in the
pipeline, but they're not in a released kernel yet.

Thanks. That explains time used on this. It ended up taking around two
hours. It also raises another question: Since I enabled compression
after having used the file system for a while will all files that aren't
compressed be compressed during the full balance process?
