zfs discuss - Dec 2008 - device error without a check sum error ?

I have a system running in a VM with a root pool.  The root pool
occasionally shows a fairly stern warning.  This warning comes with no check
sum errors.

bash-3.00# zpool status -vx
 pool: rpool
state: ONLINE
status: One or more devices has experienced an error resulting in data
       corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
       entire pool from backup.
  see: http://www.sun.com/msg/ZFS-8000-8A
scrub: scrub in progress for 0h1m, 7.03% done, 0h13m to go
config:

       NAME        STATE     READ WRITE CKSUM
       rpool       ONLINE       0     0     0
         mirror    ONLINE       0     0     0
           c0d0s0  ONLINE       0     0     0
           c0d1    ONLINE       0     0     0

errors: Permanent errors have been detected in the following files:

       //dev/dsk


My question is can i safely ignore the warning if there is no check sum
error ?

Thanks

It appears as though you added the mirror using a whole disk,
which will not be bootable.  You will need to detach the c0d1
side, change the EFI label to an SMI label, and reattach.  The
proper procedure for configuring bootable mirrors is in the ZFS
Administration Guide.
