I'm sure you can

I'm doing one tomorrow if you don't have an answer by then

Hmmm...maybe it's because I'm using UFS. I'll try with ZFS.

You can do it but not through the interface:

zpool create tank mirror ds0 ds1
zpool add tank mirror ds2 ds3

Then import through the interface.


Edit:

I learnt how to do this here:

Turns I missed the 'zpool export' command.

Last time I used Raid 5 I had 2 drives of the 4 die within 2 hours of each other. It was completely gay...

sounds like something on your end killed those drives, perhaps a UPS would be a good investment

Similar situation here. I had my machine lose power during the verify/rebuild after one HDD died. Lost the array and had to buy R-Studio to recover the data from two of the remaining uncorrupted drives, took many many many hours ...

Given a verify/rebuild can take hours with onboard/software RAID during which time it is extremely fragile and you're not even supposed to cleanly reboot until it's finished, I'm never touching software RAID again. Would go a hardware controller, but that's some serious $$$.

perhaps a UPS would be a good investment

Costly for a decent one, and with its own risks. Bought a few regular $150-200 ones for work for non-critical applications. One of them actually smoked and caught fire on its own. A similar UPS I had at home blew the motherboard of my PC when the power cable was knocked.

Dammit, stupid editing timer...now to figure out why Apple screwed with AFP. Can't use FreeNAS with Time Machine unless I make a lot of changes it seems. Fail Apple...fail...
