I said step by step. thats not what you did. what plug did you pull? when did what(heartbeat) change whom to secondary or primary? you know what single failure multiple failure multiple communication channels splitbrain stonith is? look also into your heartbeat (debug) logs. from the log provided, you provoked a split brain, you had no stonith, you did independendly multiple actions on both servers while they were not connected and could not communicate, and both nodes have been switched into secondary state again before reconnecting. we try to handle detection of splitbrain better in drbd 8 using uuid tagged data generations, but drbd 0.7 still does event counter based data generations, and so if independent events happen on both boxes while they are not connected, the "magic" to detect which is the newest data generation is likely to fail; they may even decide that they don't need any sync at all while they have completely different data sets. so don't do that. -- : 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.
