2 drives failed, need to rebuild, FreeNAS 11.0-U3

[GlassVial]

2 drives failed and both have been replaced, but I can't seem to figure out how to rebuild my ZFS RAIDZ2 (RAID6) array, I found some tutorials but they were outdated, help is appreciated!

I can't seem to figure out how to rebuild my ZFS RAIDZ2 (RAID6) array,

The manual and the resources didn't help? Replacing a failed disk is pretty well documented--what parts were you having trouble with?

 

[GlassVial]

I don't have any disks showing offline, I didn't know I had to manually put the disks to offline status first, so do I have to re-install the failed disks again, tell the system they're offline then replace or what?

Ignore the 2 UNAVAIL entries, those are cache drives.

Again, as you can see in the pics, I have no offline disks.

I can see nothing useful from the pics. *plonk*

Post the results of zpool status in code tags. Please post it here - not on an external site.

As @danb35 said, that screenshot isn't useful.

Edit: I made some notes, the serial numbers above ending in 46TK and KH6E are the 2 drives that died.

I think I got it, it's Resilvering now, I told it to replace the disks for the unavailable drives (there was no option to toggle them offline) and I told it to replace one each with the new drives I had installed. It gave me some message about a partition or something, and I checked the box to force it. This is probably going to take awhile!

Thanks for the help @gpsguy, your tip with the zpool status was really helpful!
