I’ve decided to bring this forward a bit. This is somewhat motivated by the need to get spam[34] up and running so that Adam can start to move his build scripts to target the MBS deployment infrastructure.

And by default it’s worse than that. Lesson is, if you want it configuring, do it yourself.
Personally, I don’t want it configuring, so it can sit and rot. Fuggit.
I’ve just physically plumbed in to the deployment & management network two new boxes, spam3 & spam4. These will be targeted by an MBS instance for deploying SpamAssassin (& co) configurations onto.
There’s finally a light at the end of the tunnel with the filestore work. Once the HBAs turn up I’ll be putting a new NFS server in place. This impacts on the appinf work in two major ways:

Well, that’s been a busy day. New SataBeasts arrived, they’ll be installed not a moment too soon.
I’ve rebuilt the first NFS node (munter) and captured the rest of the configuration alterations. Getting it all down in a series of Makefiles has certainly paid off.
There’s news on alternative machine rooms; so now at least we have something to aim at.
Small issue: solaris cron doesn’t set up much of an environment, and /dev/tty won’t show up.

So, we’re on day two now and I’m about at the point where I have a working software stack that’ll let me start to build heartbeat.
This is not productivity.
Productivity is typing apt-get install heartbeat and, 20 seconds later, worrying about the configuration.
OpenSolaris is promising better things with package management. 15 years too late, perhaps, but thank Christ.
Having been off for most of the week with a stinking head-cold has let me take a step back and figure out what I need to be doing over the next six weeks:

I can’t even tell from the docs if I should expect TSOL NFS to do what I’m after - irritating when reading the source is actually looking like a faster way to find out the answers. Certainly I’m unimpressed thus far with the multilievel stuff. Bah.
OK, now I know why this isn’t working. Basically any array (Nexsan speak for Raid Group) is owned by only one controller at once - and its LUNs are only delivered via a single controller.
If we’d used QLE2462s and dual-attached the X4100 then we’d see multiple paths to LUN20, but they’d all go via SB c0. If the array is failed over to SB c1 then they’d show up there instead.
What I now need to do is to set up MPxIO, configure the first paths to the LUN, then try administratively failing its owning array over to the other controller. It remains to be seen whether this will “just work” or whether I need to further configure MPxIO to know that both results are basically one and the same thing (or even if that’s actually possible).
In any regard, this is looking very good.
At the other end of the problem, we installed the trusted extensions to Solaris which appear to permit multiple NFS views. We’ll confirm or deny this shortly. TSOL is a bit of a pain to configure - hopefully we can keep the setup requirement to a minimum - if Solaris 10 grows zonable NFS service (or I build a userland NFS server which I can configure myself) this might become more straightforward.
Zoning changes get picked up properly…
