Fedorcore 5 and clustering

[RichP]

Need some pointers on clustering FC5, tried openmosix, the beta is the only one that supports 5 but I can't get it started, tried an earlier verison but the changes between 3/4 and 5 are massive, won't install. Company policy is open source only... going to see what solaris X86 has now that they have gone open source..

This may be dated but I found UltraMonkey to be pretty decent.

I'd also suggest a different distro - something more "stable" like Suse or the like (I'm a Gentoo head but stable and Gentoo can't be used in the same sentence wrt clustering).

What kind of clustering are you trying to do? Load, reliabilty or compute?

[RichP]

Load, want to setup two apache/tomcat/jboss servers and have them share the load then add new servers as needed. Have two supermicro 1U units to start with and 2 more that I can add. Openmosix works with FC3 and 4 but FC4 is still unstable, FC5 though appears to be rock solid. Want something I'm not going to have to upgrade for ~3 years.

Well, if you don't want to have to do any upgrading I'd be worried about using Fedora. We went to Fedora 1-2 from RH9 initially but between the aggressive release cycle and the fedora legacy project only seeming to go 12-18 months back we ended up with a bunch of usupported boxes in under 3 years.

That was one of the primary motivations for going to Gentoo actually, never have to "install" the operating system from CD again as long as you keep it relatively current.

If openmosix does what you want, what other distros do they say they support? ... Just looked at the web page. Appears to support anything 2.4 (yuck) with ebuilds and debs available for Gentoo and Debian.

I dunno, I don't think I could go back to a 2.4 kernel at this point.

Here's UM: http://www.ultramonkey.org/ Of the two supported OS's I'd be inclined to go Debian unless you want to try to make it work with your prefered OS. I couldn't quickly discern if 2.6 was supported (Debian Sarge is what?) - last time I used it 2.6 wasn't out yet.
