This is an "everything is going well, here's what I was up to today" email, so skip if you are busy.
'Tis the season of technical tinkering, and I've been chatting with the linux-raid folks on a variety of topics. [1] With the gen7 hardware installed a few months ago, The Mail Archive has plenty of disk space, but we were struggling a little bit to keep up with the ever increasing rate of page requests. I'm not sure the problem was user noticible yet, but eventually there would be occasional delays in serving up web pages during peak periods. This is simply due to server disks being overtaxed; there are only so many of them, and they can only seek so fast. So as of today, I've added expanded the RAID to increase the number of disks involved in serving live data. We now have three complete copies of all the message pages in active use (i.e. not counting backups), up from two previously. This allows the load to be spread across more disks, which should help satisfy the ravenous hordes for a little longer. I'm not expecting problems, but as always, please speak up if you encounter anything odd.
