Yeah, copying them all back on has gone event free, now running some balance passes to clear up the 310G of slack allocation.
I did realize that something I'd claimed earlier wasn't true: there were 3 files larger than a gig in the apt mirror snapshots, so large files in snapshots could have been contributing to the issue (If I'd realized that before moving all the large files off I'd have tried moving just those few off) Thank you all for your help. This file systems possibilities do excite me, the future is bright.
