Yes, I actually used those ebuilds to test Lustre on our "mini" 3x3 hyperwall which runs Gentoo. I was able to get it working, but over here they want the supported, released version, whereas those ebuilds are for the beta. I tried to install the released version, but eventually ran into problems. Also, since getting support from CFS is a requirement, that restricts the OS choice to specific versions of Suse or Redhat. The beta is supposed to become stable and supported by what was January, but now has apparently been pushed out to March. :( The only chance of putting Gentoo on the nodes of this cluster is if we can decide to go with the version that is still currently in beta. This is because the beta, version 1.6, has a "patchless client", and so CFS is agnostic about OS on the client side. For the server side, support=Suse as far as anyone I've talked to is concerned. > > > I'd be grateful for any feedback I get from others on the list about the > > clusters they maintain or use, and perhaps some comments about the efficacy > > of Gentoo in an environment where stability is very important, and how > > system administration compares to administration of a Suse or Redhat cluste > r. > > The main difference is that, since we're "live," you need to consider > how you want to deal with upgrades.

I attached it. > I'd very interested in the different approaches here. I had thought about a static portage tree, but that left the problem of getting needed updates, especially GLSA's. Your suggested approach sounds very interesting. How big of an extra administrative burden does that create? Maintaining our own version controlled portage tree might be a hard sell. Thanks for the script - I'll take a look at it. Is there any documentation out there about a static portage tree? -bryan P.S.: I checked out SiCortex at SC06, and talked to one of the guys there. Its definitely Gentoo. It sounds like they are a bunch of Gentoo enthusiasts, actually. -- gentoo-cluster@gentoo.org mailing list
