Not sure this is the right answer without further information about your setup - what you have and where you're headed (you have 2 disk MD RAID 1... and are moving one of the disks to a new server? going to have DRBD on top of MD?) but... You should be able to add the the meta data to the existing array with something similiar to this: http://lists.linbit.com/pipermail/drbd-user/2009-February/011464.html Then removed the mirror drive and do a "truck-based" replication explained here - specifically appropriate case listed under #2: http://www.drbd.org/users-guide-legacy/s-using-truck-based-replication.html HTH Jake _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
