Btrfs balance
Quoted 5 lines
Here (Kernel 2.6.37, btrfs git Nov. 2010): balancing two disks/ partitions with 2 and 1.5 TByte needs about 24 hours (CPU 1.5 GHz).
What do you mean with "lots of IO"? the messages in "
/var/log/messages" and "/var/log/warn"?
Simply disk activity.
See i.e. "iostat -k 1".
