What does your zpool look like? Ideally if you're using RAIDz or RAIDz2 then you should be using multiple RAIDz sets in the pool. This way IO is stripped across the RAIDz sets and any degradation, and recovery, should only involve the smaller RAIDz set. Which should be relatively quick depending on the size and type of drives involved.<div>

But ZFS only reslivers the used space and not the entire drive like with hardware solutions. So ZFS should rebuild faster than most other solutions.<br>

hours a day it's copying data from production servers.<br>

It's a Random Box of Parts with 16 1.5TB disks running OpenSolaris<br>

Its sister server is FreeBSD with 24 2TB disks, and I haven't yet had<br>
to replace a drive, but I'm hoping it won't take six days.<br>
