Nope. You DID make backups right?

I always thought that one out of three can be broken without harming the array... was I wrong ?

You have 2 disks offline plus one unavailable(3 total "bad" disks). RAIDZ2 can only handle 2 disk failures. If a 3rd disk fails its game over for the zpool.

This sounds like a dire situation. I would suggest you contact a data recovery company before you do anything else. Perhaps they can bring one of the three "bad" or missing drives back to life.

If you do contact a data recovery company make sure you explain to them that you are using ZFS. If you find one you should post back with what company it was. Nobody that has contacted data recovery companies could find one that would do ZFS, not to mention once they hear the price tag they decide they aren't going to pay for it(typically I've seen quotes starting at $2500 and only going up). But if the boss is at fault for not letting you spend money on replacement drives then I'm pretty confident that if that data was important to him he'll let you buy hard drive next time you tell him you need some for spare.

I'm sure it will be quite expensive. But the good news is that they only need one of three drives to spin up and I would think there's a reasonable chance one has a failed circuit board or other "fixable" problem. That seems easy enough to diagnose and worth investigation.
