ZFS: Block size error

[nORKy]

Hi, zpool status returns this error:

config:

	NAME           STATE     READ WRITE CKSUM
	zroot          ONLINE       0     0     0
	  mirror-0     ONLINE       0     0     0
	    gpt/disk0  ONLINE       0     0     0  block size: 512B configured, 1048576B native
	    gpt/disk1  ONLINE       0     0     0  block size: 512B configured, 1048576B native

How is this value '1048576B' possible?. I can read 1M, right?
How can I solve it?

Thanks you.

Hi again,

I changed my RAID controller and the memory card on the RAID controller, the error is still here.
FreeBSD version is 10.0.

The dmesg :

It boots complety but the system is very very slow, I don't known what to check/do.
