Thank you everyone for all the helpful and informative replies. I ended up
using zfs without encryption in a configuration similar to what David had
suggested. To summarise:
1. I was concerned hiding the SAS drives behind cgd could interfere with
low-level fault tolerance mechanisms of zfs

Since the standard devpubd hooks now run without /usr, we could
make this official.
There is no

I've not been brave enough to rely on zfs quite yet, but can confirm
that for the most part cgd + raidframe work... though the autodetect
can be a little problematic at times.
In regard to the zfs + cgd, with the cgd atop the zfs volume... I am
not sure that is wise based off of a thread a few

*tl;dr* Is it sensible to use zfs on top of cgd or are there drawbacks w.r.t.
zfs expecting raw I/O?
(Too many) details follow.
I plan to re-purpose a circa 2012 Supermicro server for a cheap home NAS. It
comes with an LSI MegaRAID

I didn't use quite as many layers, but I tested this some time back and
did not have any particular
If anecdotal evidence is helpful, I'm using ZFS with CGD
(ZFS on GPT on CGD on GPT...) without problems and I know at least
one other developer is doing the same.
