hi, and thank you for your response Mark, I don't really get everything you are saying.. and I also don't get everything about drbd... and it is worst when trying to find out how drbd and heartbeat deal together...
As I saw that my drbd service was only running on one node, and I did'nt know if it was right or wrong (even if it seemed wrong to me), I decided the tutorial you made and to install drbd-8.0.4... As I am now getting a new error, I will create a new thread, but if you can explain me a bit about how drbd and heartbeat+drbd works, I would be pleased :) thanks, Sébastien Lorandel On 7/24/07, Mark Schoonover <[EMAIL PROTECTED]> wrote:

When the primary is running, or the secondary node hasn't been promoted to primary, /dev/drbd0 is busy so both nodes can't write at the same time to the resource. Hope this helps. -- -- Mark Schoonover, CMDBA [EMAIL PROTECTED] http://marksitblog.blogspot.com Cell: 619-368-0099 Database Administration * System Engineering * Software Development * _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
