About my raidz named zdisk.
cfgadm just talked about usb... should I have some option or switch after?
I have tried to follow this guide from Larry.
I think I manage to change the status for disk c2d1p0 to not be
to open, to 'was /dev/dsk/c2d1p0' , and the disk get an id-number instead.
On the screen, after I have zpool status:
status: One or more devices could not be opened. Sufficient replicas exist
for the pool to continue functioning in a degraded state.
action: Attach the missing device and online it using 'zpool online'. "
As I understand the red text says it's possible to 'Attach' the missing
device and online it with 'zpool online'. but I get:
~# zpool online zdisk /dev/dsk/c2d1p0
warning: device '/dev/dsk/c2d1p0' onlined, but remains in faulted state
use 'zpool replace' to replace devices that are no longer present
But how do I use the 'zpool replace' ?

About rpool degradation. I have got a checksum error just after a few days..
so my qustion is if it wrong with my harddrive or it just a coincident?
'iostat -e' or 'iostat -E' did not show any Soft, Hard or Transport error on
my system/root disk (where the rpool are.) . No, there are no redundant on
that disk, so there are probably nothing else to do than replace the
corrupted files (as being visible with -v. .. or reinstall...
