Accidental mangling of config files on primary will be instantaneously transferred to secondary. > 2. Unknown demons that will present themselves when I install new software. 3. no mountable root file system :) remember: you cannot have it mounted on both nodes at the same time. even with drbd 8 and "shared disk mode" this would not make much sense. I don't think anyone out there actually has its root file system, or other mostly static (only changed once in a while during maintenance downtimes) areas on cluster file systems... -- : Lars Ellenberg Tel +43-1-8178292-0 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Schoenbrunner Str. 244, A-1120 Vienna/Europe http://www.linbit.com : __ please use the "List-Reply" function of your email client.
