yars_balance - Fix all files
version 1.33
% yars_balance
Rebalance files in the yars cluster so that all stashed files are returned to the correct server. This was originally done using the yars_fast_balance command, which is buggy and not as fast as this one.
The number of threads to run in parallel. Only one thread per disk will execute at a time.
After copying files to the correct bucket (either as a local file copy, or as a Yars file transfer), rename the original file to a backup directory, instead of unlinking it. This is particularly useful when adding new untested disks to a yars cluster.
Delay deletes or renames to avoid race conditions with GETs. Note that this introduces a race condition with DELETEs.
Pause balance when load average exceeds number. Only implemented on systems that provide /proc/loadavg, such as Linux.
