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?

maybe you need to specify block size (bs= see the mount manpage) when mounting or... the man page says it can only be as big as pagesize. Check your page size `$ getconf PAGE_SIZE`, maybe that's the problem.

Good luck Patrick

The page size is currently 4k. I'm running "Linux domU-12-31-36-00-51-72 2.6.16-xenU #1 SMP Mon May 28 03:41:49 SAST 2007 i686 athlon i386 GNU/Linux". I there a 2.6.22 or later kernel available?
