So I'm playing around with S3 and elasticdrive, and I create a filesystem on it with a block size larger then 4k.
mkfs.xfs -b size=8k /mnt/ed5/ed0 -f

This completes fine and sets up the proper filesystem. When I try to mount it, however, I get:

mount /mnt/ed5/ed0 /mnt/eds35/ -o loop


mount: Function not implemented

looking at dmesg I get:

XFS: Attempted to mount file system with blocksize 8192 bytes
XFS: Only page-sized (4096) or less blocksizes currently work.
XFS: SB validate failed


I had similar issues with reiserFS. Is there a way to get a filesystem with larger then 4k blocks in CentOS 5?

Looks like I would need something like this:

does anyone know wh ether this is part of CentOS yet, or if there is some sort of binary available?
