Not sure if it's been considered or not. If you have disk that can be physically shared between two hosts, either via SCSI, iSCSI or FC or some other mechanism, why not just create a metaset out of the disk, share the metaset to the 2nd box.
Now, this doesn't allow full R/W + R/W on both boxes, however, if you set up box b to monitor box a, if box a goes down, box b forces a takeover of the metaset, mounts the filesystem (performs fsck if necessary), starts the mail service on the *backup* server. Then you aren't having to worry about continuously synchronizing filesets over and over again. It's simple to implement, and if you have something at the front end that can intelligently route the mail traffic - possibly even configure a virtual NIC that uses the same IP address as the primary server, so that it comes up just prior to re-enabling the service. Just a thought... This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
