comment How do you create large, growable, shared filesystems on Linux at AWS?
Thanks, Petr. I had considered (and forgotten) the LVM+XFS combo. I have some trepidation about LVM2 and XFS, mostly around uncertainty and new operational complexity for us. I don't expect to get something for nothing (i.e., expandable storage for no effort), but I would like to minimize the effort and risk for us. For example, what's the implication of losing one EBS volume that's part of a RAID1 array? It might be a non-issue, but at this point such questions create uncertainty for me. In an era of ZFS and btrfs, I was hoping to sidestep such complexity.

Good question. The answer is sorta, but we're early. Our data need is high and compute need is bursty. So, it's not clear which costs more: AWS with expensive storage and cheaper peak computing solution, or local with expensive computing and cheaper storage. (I'm not even convinced that the fully loaded storage cost really is cheaper.) We'd probably stash archive data in Glacier to reduce cost (the constraints happen to work for us).
