Rebuilding Indexes, DB now 10x the size
In the meantime I just figured this out, total brain burp. I had indicated what I thought was a fill factor of 90 in the rebuild job, but it's worded as "change free space percentage to" so by using a value of 90 in there, I was actually using a fill factor of 10!! DOH. No wonder it grew 10x as big. I'm going to rebuild with the correct fill factor then shrink. Thanks to everyone for the input though.
