Re: [Fwd: Re: [Linux-HA] Heartbeat compatibility question]
The log from Patrick Begou shows the communication is dead among the two nodes after their initial communication. I tried the combination (1.2.3 2.0.8) with a simple IP address v1 style resource. The communication is fine, one node can see the other node without problem. However the resource cannot start or fail over correctly. Two 2.0.8 nodes v1 style resource work correctly though. I opened a bug for this (#1544). -guochun Alan Robertson wrote: Looks like something is broken between 1.2.x versions and 2.0.x versions :-(. This is the 2nd complaint about this in the last week.

It was just to give some feedback to heartbeat users wich could reach into this situation. Now heartbeat 1.2 runs fine and my HA cluster is available with one node in Sarge and one node in FC6. I will setup the second node and update heartbeat to 2.08 in the next weeks.

Re: [Linux-HA] Heartbeat compatibility question
Just to give some final info on this thread: - Heartbeat version 2.0.8 do not works with heartbeat version 1.2.x. i had to install two identical versions on the two nodes (downgrading FC6 official version) - version 1.2.x works without major problems between a node Fedora Core 6 X86_64 and a node Debian Sarge AMD64. The main difficultie is for the haresource file. The documentation should be changed a little in the sense that: haresources should not be identical but should provide the same behavior as ressources names can change with OSs: - bind9, in Debian, is named in FC6 - nfs startup is different in the two OSs - etc... One of the main problem in this situation is also different uid for the owners of sendmail, named services and different version of these services not fully compatible with the shared data files. It is not fully solved for me! It is quite difficult to move one HA node to a new version (with the other one in production) and then update the second one while the first is in production! Thanks all for your help and precious advices.

I wonder if you ran into bugs here. BTW, I don't think you posted any logs. Also, why is it that you wanted to run 1.2 with 2.0? - version 1.2.x works without major problems between a node Fedora Core 6 X86_64 and a node Debian Sarge AMD64. Good. heartbeat should run in a mix of platforms. I think I can recall somebody having a solaris/linux cluster. The main difficultie is for the haresource file. The documentation should be changed a little in the sense that: haresources should not be identical but should provide the same behavior as ressources names can change with OSs: - bind9, in Debian, is named in FC6 - nfs startup is different in the two OSs - etc... Hmpf. In cases like this it would be best to use the heartbeat supplied resource agents. And, if those don't exist, to write one or, as an ultimate resort, adopt one of the two for the other platform. One of the main problem in this situation is also different uid for the owners of sendmail, named services and different version of these services not fully compatible with the shared data files. It is not fully solved for me! :) You'd have to manually fix the IDs to match on all nodes. Heartbeat can't help here. It is quite difficult to move one HA node to a new version (with the other one in production) and then update the second one while the first is in production! Yes, for v1, but with the v2 (CRM) kind of cluster it's a peace of cake. Thanks all for your help and precious advices. Welcome. BTW, did you reach any conclusion regarding the crashes?

Runing heartbeat -k hangs, like if it was waiting for ever a response from the otrher node. I'make these tests without iptables nor selinux runing. I do not see anything in the log files (debug set to 1, then 2, then 3) except the pings to the nodes wich was successfull. Also, why is it that you wanted to run 1.2 with 2.0? Smooth transition: moving one node to a different OS, testing, moving the services on it, updating the other node, re-activating the HA cluster.

BTW, you can always try the vanilla kernel and then bother people on the kernel list ;-) So many tests run on the hardware for these 2 years... - hard drive checked (with constructor softwar) OK. New low level initialisation and re-install. Same problem. - memory test for 72 hours with the latest memtest version. No error. - mother board change. Same problem. - Power supply change. Same problem. - Adding additionnal fan to the unit (even if the room is maintained at 22 degres). Same problem. As the problem occurs on the 2 hosts but not simultaneously (usualy) I think it is a software problem. But I cannot get any info when the host crashes (nothing in the logs and only partial info on the console). May be I can again try a new kernel before removing Debian...
