Dear List, I now have a different problem, which might cause us to stop using o2cfs.
We still have two HP-machines, redundantly connected to an HP-san with an EVA 6000. Each has two network cards which are bundled with bonding.o as active-standby. They are connected to a switch. Now, if there is a problem with the network, or if one machine is disconnected from the switch: Both machines are self-fencing! Installed are: rhenad:~ # rpm -q ocfs2-tools ocfs2-tools-1.1.4-0.5 rhenad:~ # rpm -q ocfs2console ocfs2console-1.1.4-0.5 We cannot really make an update, at least not a kernel update, as we will loose SAN certification and experiments show, that the SAN and failover won't work than. Oh yes, all this is from SLES9 SP3 Question: Of course, our main idea to use ocfs was, that if one node crashes or looses network connection or something, that the other one survives. At the moment it seems, that if one node has problems, both are self-fencing. What is the official opinion here, and what can we do to address that problem? Would having each link of the fault-tolerent pairs on a different lan switch (for redundancy) help? This way, a lan-switch lockup (as it happened on us) won't be a problem, however, if one(!) machine crashes or looses network connection, is there a chance for an ocfs2 cluster to survive? Thanks in advance, Michael. --- Dr. Michael Weller ITZ Informationstechnologie GmbH Consulting/Systemengineering Bismarckstrasse 57 D-45128 Essen Phone Office +49 201 24714 28 FAX Office +49 201 24714 33 Phone Mobile +49 172 2178078 E-Mail mailto:[EMAIL PROTECTED]
