Flight (Mar 29 2011)

Well, we had more data pipeline issues over the weekend resulting in low work production, but we cleaned that up on Monday and I added yet more AI to the whole suite of scripts to hopefully get beyond more potential snags.

Today was our usual outage day and we made the most of it. Besides the usual mysql database compression and backup, we took care of the following:

1. Got the seemingly broken 3510 fibre-attached RAID on jocelyn out of the closet, and replaced it with a fibre-attached JBOD which we already had lying around. A software RAID partition is syncing up as I type this.

2. Built another fragmented index for one of the signal tables on the science database and played around with some speed tests.

3. Finished moving over by hand the remaining workunits that were copied elsewhere when the workunit storage server locked up a month or so ago.

4. Did all the tweaking necessary on all the systems to let go off internal server ptolemy so we could shut it down for good. Yet one more 32-bit machine retired.

5. Noticed that synergy rebooted itself a couple times this morning, so we took it off one potentially flaky power strip. Man that system is sensitive to slight power fluctuations. At least we hope that's the case.

6. With ptolemy offline Eric immediately cannibalized one of its drives to use in one of his hydrogen study database servers, which had a recently failed drive in it.

7. Replaced the failed drive on our raw data storage server with one of many kindly donated (once again) by Overland Storage.

I think that's about it, minus some less interesting details.
