RE: [CentOS] mounting filesystems with blocks larger then 4k over aloop device

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?

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
