'I try to save a life a day. Usually it's my own.' - John Crichton
First I'd like to note that contrary to the nomenclature there isn't any one
SAN product that all operates the same. There are a number of different
vendor provided solutions that use a FC SAN to deliver luns to hosts, and they
each have their own limitations. Forgive my pedanticism please.

quickly, and then get those files recovered from backup afterwards as
needed, without having to recover the entire pool from backup.

consumer drives and my servers all have ultras.
Most modern boards will be boot from a live USB stick.

Silly question - you're not trying to have the ZFS pool imported on
both hosts at the same time, are you? Maybe I misread, had a hard
time following the full description of what exact configuration caused
the scsi resets.

Definitely not a silly question. And no, we create the pool on

It's clear from some threads on this list that it IS possible to roll
back a zpool to a previous state, and I seem to even remember reading
someone was working on a tool or tools in that direction.
Is that correct, is it possible to manually roll back a zpool for crash
recovery purposes, if
Does creating ZFS pools on multiple partitions on the same physical drive still
run into the performance and other issues that putting pools in slices does?
