To my surprise I discovered today that 3-way boot mirrors are not supported in 11.1-U7
Booting off USB is useful because it uses "free" external USB connections.
With a lot of existing hardware, anything else ends up using connections that could be assigned to storage pool resources instead.
Even though USB sticks are ridiculously crappy and short lived, they are also ridiculously cheap, and many systems have a multitude of USB 2.0, or higher, connections sitting un-used.
Absent a particularly tricky bit of programming, why limit boot sticks to 2-way mirrors when increasing boot pool redundancy to 3-way or 4-way or higher would ensure that scrub has enough information to correct errors even under extremely unlikely conditions-while the incremental hardware expense is at the level of a cup of coffee?
Is this supported with later releases? Did it use to be supported and it no longer is?
Thank you and my apologies if this has been addressed in the past, or should be in a different forum location!
