Hi Mike,
It is difficult to comment on the root cause of this failure since
the several interactions of these features are unknown. You might
consider seeing how Ed's proposal plays out and let him do some more
testing...
If you are interested in testing this with NFSv4 and it still fails
the same way, then also consider testing this with a local file
instead of a NFS-mounted file and let us know the results. I'm also
unsure of using the same path for the pool and the zone root path,
rather than one path for pool and a pool/dataset path for zone
root path. I will test this myself if I get some time.
Thanks,
Cindy

I've been playing around with zones on NFS a bit and have run into
what looks to be a pretty bad snag - ZFS keeps seeing read and/or
checksum errors. This exists with S10u8 and OpenSolaris dev build
snv_129. This is likely a blocker for anything thinking of
implementing parts of Ed's Zones on Shared Storage:
http://hub.opensolaris.org/bin/view/Community+Group+zones/zoss
The OpenSolaris example appears below. The order of events is:
1) Create a file on NFS, turn it into a zpool
2) Configure a zone with the pool as zonepath
3) Install the zone, verify that the pool is healthy
4) Boot the zone, observe that the pool is sick

An off list conversation and a bit of digging into other tests I have
done shows that this is likely limited to NFSv3. I cannot say that
this problem has been seen with NFSv4.
