Hi Brian,
I don't think data corruption occurs cleanly within a
file system boundary.
What kind of permission changes?
This looks like the mode/permissions of this file system
are messed up but something much worse happened.
Thanks,
Cindy

Cindy,
Thanks for the quick response. Consulting ZFS history I note the
following actions:
"imported" my three disk raid-z pool originally created on the most
"recent" version of OpenSolaris but now running NexantaStor 3.03
"upgraded" my pool
"destroyed" two file systems I was no longer using (neither of these
were of course the file system at issue)
"destroyed" a snapshot on another filesystem
played around with permissions (these were my only actions directly on
the file system)
None of these actions seemed to have a negative impact on the filesystem
and it was working well when I gracefully shutdown (to physically move
the computer).
I am a bit at a loss. With copy-on-write and a clean pool how can I
have corruption?

Brian,
You might try using zpool history -il to see what ZFS operations,
if any, might have lead up to this problem.
If zpool history doesn't provide any clues, then what other
operations might have occurred prior to this state?
It looks like something trappled this file system...
Thanks,
Cindy

Thanks Preston. I am actually using ZFS locally, connected
directly to 3 sata drives in a raid-z pool. The filesystem is
ZFS and it mounts without complaint and the pool is clean. I am
at a loss as to what is happening.
