Ok. What is your ultimate goal? Is it to:
- run the first scrub
- search for an "ok" err status upon return
- begin the second scrub
If (in your case) the first scrub fails, is it still feasible to run the
second scrub anyway? If it is, then chaining the commands together
*should* work (however, I've never tested whether '&&' will continue
upon certain 'failures', but so long as the first command _exits_, you
should be alright).
If your X doesn't finish correctly, and then you can't run Y because of
it, what would you be looking for in the following manual output to
signify error?
%zpool status
pool: storage
state: ONLINE
scrub: scrub completed after 2h50m with 0 errors on Thu Jul 9 11:56:39
2009

ps. I use ZFS in a limited capacity... I'm just trying to help write a
wrapper if one doesn't currently exist.
