zfs discuss - Jan 2009 - ZFS upgrade mangled my share

I was having CIFs problems on my Mac so I upgrade to build 105.
After getting all my shares populated with data I ran zpool scrub on  
the raidz array and it told me the version was out of date so I  
upgraded.

One of my shares is now inaccessible and I cannot even delete it :(

This is pretty scary for something that''s storing valuable data.

Any ideas how I can destroy the dataset and recreate it?

Thanks

There''s a typo there, you would have to do

zfs destroy nas1/backups

Unfortunately, you can''t use the mountpoint, you have to name the
dataset.
