Thanks for the info. I know its quite old but I cant update as its running with cluster suite and its a production unit. Â Moreover its not feasible to upgrade as I have hundreds for apps and data lying on the system.Backing all of this not very continent.Â
First of all, you can update to 5.10 using yum (a 'yum update' will automagically update to 5.10). I don't know how this would affect the clustering, though.
Oh, and btw, we have both H/A clusters and heavy-duty scientific computing clusters. The h/a's have not been any problem upgrading. We're very cautious on the scientific compute clusters, only because when we went, I think it was, from 5.x to 6.x, or there were mathematical inconsistencies that *may* have been from glibc. Those seem to have been resolved, but they push back until they can verify the results via regression test.
You *do* have a test system or cluster for them to regression test on, right...?
