On Vacation In Michigan, RAID problems
I’ve been in Michigan for a few weeks now with my wife and her family and will be here another week. Internet access is at best intermittent, so I haven’t (and won’t) be blogging much.
The technical highlight so far has been trying to troubleshoot problems with the RAID on bostoncoop.net over a cell phone while at the county fair, surrounded by pigs and alpacas.
Speaking of RAID problems: can anyone suggest why more than half of our 200G drives would fail in various ways within a year of installation? They are from various manufacturers (WDC and Maxtor), and have failed differently, and some are giving SMART errors only days after installation. Almost all of the other equipment is new as well. Most commonly the failure shows up as kernel DMA errors, which as best I can tell don’t really point to any particular cause. We suspect temperature problems—is 50-60 celsius enough to be a serious problem?
In particular, I’d appreciate any suggestions as to how to limit the problem to hardware vs. software, hard drives vs. controller(s) vs. motherboard vs. memory… And so forth.
