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 David 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 ;)
