zpool status is showing everything ok:

marck@moose:~> zpool status
  pool: m
 state: ONLINE
 scrub: none requested
config:

	NAME        STATE     READ WRITE CKSUM
	m           ONLINE       0     0     0
	  raidz1    ONLINE       0     0     0
	    ad4h    ONLINE       0     0     0
	    ad6h    ONLINE       0     0     0
	    ad8h    ONLINE       0     0     0
	    ad10h   ONLINE       0     0     0
	    ad12h   ONLINE       0     0     0
