Hi all,

We have a server with a LSI 9240-4i controller configured in JBOD with
4 SATA disks. Running FreeBSD 9.1-Beta1:

The problem:

When trying to create a RaidZ pool using gpart and perform a 4K
alignment using  gnop, we get the follwoing error immediately after
exporting the pool and destroying the .nop devices:

id: 8043746387654554958
  state: FAULTED
 status: One or more devices contains corrupted data.
 action: The pool cannot be imported due to damaged devices or data.
	The pool may be active on another system, but can be imported using
	the '-f' flag.

	Pool                      FAULTED  corrupted data
	  raidz1-0                ONLINE
	    13283347160590042564  UNAVAIL  corrupted data
	    16981727992215676534  UNAVAIL  corrupted data
	    6607570030658834339   UNAVAIL  corrupted data
	    3435463242860701988   UNAVAIL  corrupted data

When we use glabel for the same purpose with the combination of gnop,
the pool imports fine.

Any suggestions?
