I am in the process of 'physical-izing' my OI/napp-it ZFS base and host my VMs in KVM on OI instead of ESXi.
Part of the update is changing my 3-drive raid-z of 3TB WD REDs over to 4 drives, a pool made of two vdevs made up of two-drive mirror each (how do you say that more concisely?).
Initial testing with Bonnie ++ indicates a problem. I have 32 GB of RAM and the Bonnie run took about 4 hours with this result:
Obviously much much much slower than before. I can think of a few bits of trouble-shooting to do, but is this anything you've seen before?
Thanks. I'll update, probably with a solution soon
-- update. hard errors. a cable maybe, I'm hoping. That was not the new drive!:
