Everything shook out with the next fsck. Greyhol Identified the redundant copies and removed them. This was a non-issue.

Nope. I'll give it a try in IRC tonight.

I was a bit too aggressive in my redundancy settings, and a couple of the smaller disks in the pool have filled up. I'd like to reduce the redundancy for some of my bigger shares, and eliminate the extraneous copies. What's the best way to do this?
