Re: Balancing disk drives

[Jim Oberholtzer <midrangel@xxxxxxxxxx>]

What has not impressed you? That the process took a little over 8 hours 
to complete, or you do not see much in the way of a change?  I don't 
know what time period the WRKDSKSTS observation is for, if it's not 
about 5 minutes or so, it's not representative of what's going on anyway.

Maybe the system was already well balanced from a usage standpoint.  
Granted it could not have scattered it across a disk that was just 
added, but over time it would have.
