I had a volume that needed resizing, so went ahead and tried moving from a 50GB gp2 to a 100GB gp2 disk online. It took 1 hour 40 minutes to do the resize. It's not a quick operation, and from looking at the docs you're limited to 1 modification per 6 hours on any given volume.

Whoa I guess that's more or less the same as downtime. Imagine if you were out of space but couldn't do anything for 100 minutes. I am watching EFS and hoping it falls in price or that EBS that backs EC2 instances becomes more automatically elastic.

To further my point: what I'm getting at is that EFS has the chance to be the answer to persistent storage for docker swarm and just persistent storage for docker in general. But at .30 cents a gig it's just too much right now.

was it unusable during resize?

I didn't explicitly test that, though I expect it's usable as the docs suggest that after you resize a live root partition you should reboot the box after modifying the filesystem extents (resize2fs). I was modifying a scratch partition -- nothing blew up while the resize happened.
