Hi,
I have setup up a btrfs RAID1 using two 1TB drives. How long should a
'btrfs filesystem balance' take? It is running now for more than 3 days
on about 30% CPU and 40% wait state.
I am using stock btrfs from ubuntu 11.10 kernel 3.0.0
Not nearly that long. Assuming it actually has to rewrite 1 TB of data
and is only getting 50 MB/s, that should only take about 5.5 hours. You
might want to try a newer kernel ( like the one from 12.04 ).
