I am trying to find out if our hash function for object distribution
work as expected,
$ ./collie/collie node md info --all
Id Size Used Avail Use% Path
0 2.0 GB 1.6 GB 419 MB 79% /tmp/sheepdog/0/obj
1 482 MB 424 MB 58 MB 87% /tmp/sheepdog/3
0 2.0 GB 2.0 GB 0.3 MB 99% /tmp/sheepdog/1/obj
0 2.0 GB 2.0 GB 0.3 MB 99% /tmp/sheepdog/2/ob

we should make sure different sized disks won't cause cluster-full problem.
Anybody help try different sized disks combination in one node and post
