"That which is overdesigned, too highly specific, anticipates outcome; the anticipation of outcome guarantees, if not failure, the absence of grace."

Toil and trouble.

Over the last two weeks we (read: rjbs) migrated our Subversion repositories to git on GitHub. I was not very pleased with this for the first week or so. By default, I am grumpy when things that (to me) are working just fine are changed, especially at an (even minor) inconvenience to me. That is just the grumpy, beardy sysadmin in me.

After a bit more talking to by rjbs, things are again smooth sailing. I can do the small amount of VCS work I need to do, and more imporantly: I am assured things I don't care about will make the developers lives much, much less painful, which is something I am certainly all for.

git is much faster than Subversion ever was, and I can see some features as being useful to me eventually. Overall, though, what I use VCS for is pretty uninteresting, so I don't have much else to say about it.

I had a couple basic mental blocks that rjbs was able to explain away in a 20 minute talk he gave during our bi-weekly iteration meeting. It was quite productive. There are pictures.

Work has otherwise consisted of a lot of consolidation. I have finally reduced the number of horrible systems to two. Yes. Two. Both of which are slated for destruction in the next iteration. Not only that, I have found some poor sucker (hi, Cronin!) to take them all off our hands. Of course, they'll be upgrading from PIIIs, so...

I also cleaned up our racks. A lot. They are almost clean enough to post pictures of, though I'll wait until I've used up more of the six rolls of velcro Matt ordered before doing that.

Pretty soon we'll have nothing but Sun, a bit of IBM, and a very small number of SuperMicros. My plans are to move our mail storage from the existing SCSI arrays to a Sun J4200 (hopefully arriving this coming week). 6TB raw disk, and it eats 3.5" SATA disks, which are ridiculously cheap these days. I really, really wanted an Amber Roads (aka OpenStorage) J7110, but at 2TB with the cost of 2.5" SAS, it was impossible to justify. If they sold a SATA version at the low-end... there has been some noise about conversion kits for Thumpers, but that's also way outside our price range.

I doubt conversion support will become more common, but if I could turn one of our X4100s and the J4200 into an OpenStorage setup, I would incredibly happy. If you haven't tried out the OpenStorage Simulator, I suggest you do so. Analytics is absolutely amazing.

People on zfs-discuss@ and #opensolaris have been talking about possible GSoC projects. I suggested a zpool/filesystem "interactive" attribute, or "ask before destroy." However you want to think of it. Someone else expanded on that, suggesting that -t be allowed to ensure that only specified resource types can be destroyed. I have yet to bone myself with a `zfs destroy` or `zpool destroy` but the day will come, and I will cry.

I see a pkgsrc upgrade in my near future. I've been working on linking all our Perl modules against it, and I want to get the rest of our internal code linking against it as well. It will make OS upgrades so, so much easier. Right now, most code is either linked to OS libraries or to an internal tree (most of which also links to OS libraries).

We've almost gotten rid of all our Debian 3.1 installs, which is... well. You know. Debian 5.0 just came out, and we've barely gotten moved to 4.0 yet. Getting the upgrade path there sorted out will thankfully just be tedious, and require nothing clever.

I really hope that the Cobbler guys get Debian partitioning down soon, and integrate some Solaris support. I tried redeploying FAI over Christmas and man, did it so not work out of the box. I used to use FAI, and was quite happy with it. I had to hack it up, but... it worked pretty well. Until it stopped.

If Cobbler had Solaris support, I would seriously consider moving our remaining Linux installs to CentOS. We use puppet already, so in many ways Cobbler is a no-brainer. We are not really tied to any particular Linux distribution, and having all our infrastructure under a single management tools ken would be really nice. To put it mildly.

30% curious about OpenSolaris's Automated Installer project, but it's so far off the radar as to be a ghost.

I picked up John Allspaw's The Art of Capacity Planning, and it's next on my book queue. Flipping through it makes me think it's going to be as useful as Theo S.'s Scalable Internet Architectures.
