At this point, you have to think, how can my filesystem cope with the loss of a 60gb chunk of data in the middle (start or end even) of the 300+ gb of data? There's all sorts of meta-data and true data which is now gone, and re-building the filesystem into a consistent state is really impossible. Sure, you spent heroic amounts of time, you might be able to pull back lots of data from individual sections where it's still around, but in general, it's not going to happen. If you are looking for a large/cheap/reliable bunch of storage, instead of mirroring, you might want to think about RAID5 instead. In your case, you had a mix of disks, so what you could do is build a pair of RAID5 arrays using disks of the same size for each array (minimum of three disks each of course) and then stripe the filesystem across both arrays. To add more storage, you need to work on chunks of three disks, but since 120gb disks are going for around $100 these days, it's not that expensive. Good luck!
