Yes, exactly.

Woo-hoo, magic:
# zfs get refquota export/group/enrollment
NAME PROPERTY VALUE SOURCE
export/group/enrollment refquota none local
# zfs inherit -S refquota export/group/enrollment
# zfs get refquota export/group/enrollment
NAME PROPERTY VALUE SOURCE
export/group/enrollment refquota 800M received
Perfect, thanks much for the quick answer (and thanks also to Yuri for
replying).

I will open a ticket for it. Could you give a general description of its
purpose? I could dig through the code and try to intuit if it has any other
purpose besides resetting local quota/refquota updates, but the man page would
probably be more accurate if based on a developer synopsis :). Ahh, I see
Solaris 11 has it documented:
"Reverts to the received property value, if any. If the property does not have
a received value, the behavior of zfs inherit -S is the same as zfs inherit
without -S. If the property does have a received value, zfs inherit masks the
received value with the inherited value until zfs inherit -S reverts to the
received value."
I will re-work those concepts into original language and perhaps add a specific
mention of quota/refquota, which will work with -S but not without.
Would there also be an interest in updating the zfs command error output so
instead of simply:
'quota' property cannot be inherited
use 'zfs set quota=none' to clear
it could say something like:
'quota' property cannot be inherited from parent
use 'zfs set quota=none' to clear or 'zfs inherit -S quota' to revert to
received value
Unfortunately, I don't currently have an illumos build environment. I'm hoping
to get an illumos-gate development environment going on omnios-stable over
Christmas break (the OI vm I used to use blew up, and I can't bring myself to
spend the time to build another OI box). Unless they'd be willing to RTI a
basic man page change via a visual inspection/manual nroff without a full build
log, in which case I could get to it sooner. The code change, if so desired,
would of course need to wait for a development environment.
Thanks much…
