Hi all, I'm trying to accomplish server to server storage replication in synchronous mode where each server is a Solaris/OpenSolaris machine with its own local storage.
For Linux, I've been able to achieve what I want with DRBD but I'm hoping I can find a similar solution on Solaris so that I can leverage ZFS. It seems that solution is Sun Availability Suite (AVS)? One of the major concerns I have is what happens when the primary storage server fails. Will the secondary take over automatically (using some sort of heartbeat mechanism)? Once the secondary node takes over, can it fail-back to the primary node once the primary node is back? My concern is that AVS is not able to repair the primary node after it has failed, as per the conversation in this forum: http://discuss.joyent.com/viewtopic.php?id=19096 "AVS is essentially one-way replication. If your primary fails, your secondary can take over as the primary but the disks remain in the secondary state. There is no way to reverse the replication while the secondary is acting as the primary." Is AVS even the right solution here, or should I be looking at some other technology? Thanks. -Moazam _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
