As I mentioned earlier, I removed the hardware-based Raid6 array, changed all
the disks to passthrough disks, made a raidz2 pool using all the disk. I used
my backup program to copy 55GB of data to the disk, and now I have errors all
over the place.
# zpool status -v
pool: bigraid
state: DEGRADED
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.

scrub: scrub completed after 0h4m with 0 errors on Wed Apr 14 22:56:36 2010
config:

So, zfs on hardware-supported raid was fine, but zfs on passthrough disks is
not. I'm at a loss to explain it. Any ideas?
