Don't know about your mount issue, but I did notice 4096 in you dmesg, should it be 8192? I did not see any mount options for block size.
sh-2011: read_super_block: can't find a reiserfs filesystem on (dev
dm-0, block 16, size 4096)
Yep I got a response on the reiser list that prompted me to try XFS.
It rather nicely said: XFS: Attempted to mount file system with blocksize 8192 bytes XFS: Only page-sized (4096) or less blocksizes currently work. XFS: SB validate failed

PS http://www.namesys.com/mkreiserfs.html says :
-b | --block-size N
N is block size in bytes. It may only be set to a power of 2 within the 512-8192 interval.
So that might help googlers in the future ;) - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
