hosting status: April 2008 Archives

We went down last weekend due to a bad hard-drive;  all customers in the accounting system got e-mails about it... if you are a customer and didn't get an email, please complain loudly, as it means I don't have you in the accounting system.

The problem was resolved by monday;  if you are still having problems, again complain loudly.  lsc@prgmr.com is a good address to complain at. 


So, our servers are  co-located in Sacramento (at rippleweb. - I like them quite a lot for hosting 1U boxes- they are an especially good deal if you have high-density high-power boxes, as they use 208v power and don't charge extra for the power sucking older dual xeons that draw 100-200 watts per U)

So late Friday night a drive failed, and the way I have things setup, mirroring is optional and not-default, which means most customers don't.

Compounding matters, I striped the swap for the Dom0 across both drives (I mirrored everything else) so the box went down with the bad drive.

We did, however, manage to get the bad drive to spin up (after sticking it in the freezer for a while) so we should be back in business sometime late tonight.

Also, as I pointed out, these servers are in Sacramento. I am in sunnyvale. First, I login to the remote kvm setup and see what I can do in bios. Nothing; it can't even see the drive. So, I ask my friend Chris, the guy who is partnering with me on my xen book venture to take a look at it.

So, Chris drags the server back to his house. He plugs it into a new computer. No dice. He even swaps the circut board with a spare drive of the same model. Nothing. (the spare drive, with the circuit board from the bad drive, works fine) Clearly, we have a catastrophic failure in the drive itself. Violence wasn't helping, either. (sometimes drives suffering from stuction can be cured with concussive force) So, we think, why not try freezing it? people say freezing a drive can sometimes help if your bearings are failing; but it's never worked for me.

After several hours in the freezer, however, the drive spins up, and it stays up long enough for us to retrieve all the data. As Chris said, "freezing it. . . totally not myth."
