Hello Franck,

Thank you for your fast reply.

I don't see this option in share:

# zfs set sharenfs=ro=91.121.194.1,rw=91.121.194.1,root=91.121.194.1,nodevices 
tankmirror/vol1001
cannot share 'tankmirror/vol1001': invalid share option: 'nodevices'
property may be set but unable to reshare filesystem

# share -o nodevices /tankmirror/vol1001
share_nfs: invalid share option: 'nodevices'

It's ZFS for me, but under UFS I see the same bug. If you need any debug, tell 
me how I can help you.

Regards,
