XFS for Linux only supports block sizes that are the same as the size of
a memory page. On ia32 systems, this means a 4k blocksize.
Support for other block sizes is on the TODO list, but at this point,
you will not be able to mount an XFS filesystem with 512k blocks.
xfsdump/xfsrestore is one option to get the data from your Octane onto a
Linux XFS filesystem.
