Hi, 

does anybody successfully try the option sharenfs=on for an zfs filesystem
with 10000 users? On my system (sol10u2), that is not only awfully slow but  
does also not work smoothly. I did run the following commands:

zpool create -R /test test c2t600C0FF0000000000988193CD00CE701d0s0
zfs create test/home
zfs set sharenfs=on test/home
for u in `range 0000 9999`; do zfs create test/home/$u; done
zpool export test
zpool import -R /test test

The zpool export command required about 30 minutes to finish.
And the import command, after it did some silent work for 45 minutes, 
just reported a lot of error messages:

...
cannot share 'test/home/4643': error reading /etc/dfs/sharetab
cannot share 'test/home/8181': error reading /etc/dfs/sharetab
cannot share 'test/home/1219': error reading /etc/dfs/sharetab
cannot share 'test/home/3900': error reading /etc/dfs/sharetab

cannot share 'test/home/9707': error reading /etc/dfs/sharetab                  
                                                  
...

Regards,
Hans
