My plan:
I'm planning an ESX-iSCSI target/NFS serving box.
I'm planning on using an Areca RAID card, as I've heard mixed things about
hot-swapping with Solaris/ZFS, and I'd like the stability of a hardware RAID.
My question is this: I'll be using 8 750GB SATA drives, and I''m trying to

nplugging a drive (actually pulling the cable out) does not simulate a
drive failure, it simulates a drive getting unplugged, which is
something the hardware is not capable of dealing with.
If your drive were to suffer something more realistic, along the lines
of how you would normally expect a drive to die, then the system should
cope with it a whole lot better.
Unfortunately, hard drives don't come with a big button saying "simulate
head crash now" or "make me some bad sectors" so it's going to be
difficult to simulate those failures.
All I can say is that unplugging a drive yourself will not simulate a
failure, it merely causes the disk to disappear. Dying or dead disks
will still normally be able to communicate with the driver to some
extent, so they are still "there".
If you were using dedicated hotswappable hardware, then I wouldn't
expect to see the problem, but AFAIK off the shelf SATA hardware doesn't
support this fully, so unexpected results will occur.
I hope this has been of some small help, even just to explain why the
system didn't cope as you expected.

Anyone know of a SATA and/or SAS HBA with battery backed write cache?
Seems like using a full-blown RAID controller and exporting each individual
drive back to ZFS as a single LUN is a waste of power and $$$. Looking for any

I have about a dozen two disk systems that were all setup the same using a
combination of SVM and ZFS.
s0 = / SMV Mirror

services fail as well (including ssh)

Is this something that should work? The assumption is that there is a dedicated

and mounted to zpool/tmp (just like zpool/home)
Thoughts on this?

really fast as most all writes go straight to memory, but this is of little to
