Hello Bob,
Thanks for the SIIG pointer, most of the stuff I had archived from this
list pointed to LSI products.
I poked around on the site and reviewed SIIG's SATA and SAS HBA. I also
hit up their search engine. I'm not implying I did an all inclusive
search, but nothing I came across on their

It may be that you'll get reduced cabling range (only up to SATA
lengths, obviously), but it works. The voltage differences are very
small and should only come into play when you're pushing the envelope of
the cable length.

I can only speak anecdotally, but I believe it does.
Watching zpool iostat it does read all data on both disks in a mirrored
pair.
Logically, it would not make sense not to verify all redundant data.
The point of a scrub is to ensure all data is correct.

Hello all,
I was describing how raidzN works recently, and got myself wondering:
does zpool scrub verify all the parity sectors and the mirror halves?
That is, IIRC, the scrub should try to read all allocated blocks and
if they are read in OK - fine; if not - fix in-place with redundant
data or
