Issues with ZFS under remote NFS directory

[Filipe Paternot]

Hello there,

I've got an pretty weird issue with an remote filesystem which is mounted on
a given server.
Renovatio is the NFS server is running FreeBSD-7.2-release 32bit.
Neo server is running FreeBSD-8.0-release 64bit.

The problem is this:
I mount the pool rootdir at /mnt/renovatio2. Then, when i go list one of my
dirs, it shows some content that was saved (snapshot was deleted) couple
months ago for that same folder. That is weird, since im not accessing the
hidden .zfs dir, but it should be empty anyways as the snapshot was already
removed.
Then, if i mount the specific dir, it works fine.

I'm not using the zfs sharenfs option.
I am a little bit out of ideas, and not sure if its a bug too, but if anyone
can assist me, i'd be very grateful.

Thank you
