Performance-wise, I think you should go for mirrors/raid10, and
separate the pools (i.e. rpool mirror on SSD and data mirror on
HDDs). If you have 4 SSDs, you might mirror the other couple for
zoneroots or some databases in datasets delegated into zones,
for example. Don't use dedup. Carve out som
Now that I thought of it some more, a follow-up is due on my advices:
1) While the best practices do(did) dictate to set up zoneroots in
rpool, this is certainly not required - and I maintain lots of
systems which store zones in separate data pools. This minimizes
write-impact on rpools

Sure it does. You can even use the whole disk as zfs, with
Going a bit on a tangent, does anyone know if those drives are
available for sale anywhere?

Hello,
I have a degraded mirror set and this is has happened a few times (not
always the same drive) over the last two years. In the past I replaced the
drive and and ran zpool replace and all was well. I am wondering, however,
if it is safe to run zpool replace without replacing the drive to s
You don't use replace on mirror vdevs.
'zpool detach' the failed drive. Then 'zpool attach' the new drive.

And you can try 'zpool online' on the failed drive to see if it comes back
online.

Sorry, I was skipping bits to get to the main point. I did use replace (as
previously instructed on the list). I think that worked because my spare had
taken over for the failed drive. That's the same situation now - spare in
service for the failed drive.
