The pool is a mirror:

[root_at_morzine ~]# zpool status rpool
   pool: rpool
  state: ONLINE
  scan: scrub repaired 0 in 1h0m with 0 errors on Wed Aug 24 15:04:36 2011
config:

	NAME                                            STATE     READ WRITE CKSUM
	rpool                                           ONLINE       0     0     0
	  mirror-0                                      ONLINE       0     0     0
	    gptid/e915c6a0-fc72-11de-aa21-00e081706b68  ONLINE       0     0     0
	    gptid/eac8497d-fc72-11de-aa21-00e081706b68  ONLINE       0     0     0

errors: No known data errors

and rpool/root is not compressed:

[root_at_morzine ~]# zfs get compression rpool/root
NAME        PROPERTY     VALUE     SOURCE
rpool/root  compression  off       inherited from rpool

pool is v28 and filesystems are v5
