I guess when we are defining a mirror, are you talking about a synchronous mirror or an asynchronous mirror?
As stated earlier, if you are looking for an asynchronous mirror and do not want to use AVS, you can use zfs send and receive and craft a fairly simple script that runs constantly and updates a remote filesystem. zfs send takes a snapshot and turns it into a datastream to standard out while zfs receive takes a stdin datastream and outputs it to a zfs filesystem. The zfs send and receive structures are only limited to your creativity. one example use might be the following [i]zfs send pool/[EMAIL PROTECTED] | ssh remote_hostname zfs receive remotepool/fs2[/i] That would get you your initial copy, then you would have to take a snap and do incrementals from there on in with something like [i]zfs send -i pool/[EMAIL PROTECTED] pool/[EMAIL PROTECTED] | ssh remote_hostname zfs receive remotepool/fs2[/i] note that the filesystem at the other end (fs2 in thsi case) will be a live filesystem that you can use anytime. Now with that incremental commandline, you might run into a bug that is well known and you can find a work around in these forums, so I won't get into it, but your script would have to incorporate the workaround which would basically run a "[i]zfs rollback[/i]" command on the remote host before you propagate the incremental changes. ~Bryan This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
