Not unless the data is within the ZFS pool. > That is, can I nfs mount a remote filesystem on a zpool and use zfs > snapshot functionality to create snapshots of that data? No. You can't mount a filesystem into a zpool. The snapshots are easy for ZFS to do because it owns the data and it knows about every changed block. It wouldn't be able to see that on a remote NFS filesystem. The client has to scan every file (like rsync) to find changes. So a ZFS host could own the data, then *it* could be the NFS server and it would work the way you want. But it won't work if the ZFS host is just an NFS client. -- Darren _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
