As some of you will have noticed, my server galileo.mailstation.de has had some performance issues lately. Testing patches with Jenkins could take a long time, building stages was taking up to 20 hours (!) instead of the normal two and Gerrit itself could be slow at times as well.
This was due to aging hardware (that server was assembled in 2010), one horribly performing hard disk and constant over-heating of the machine. I’ve changed a few things over the last few days and performance is much better now but still not to my satisfaction.
Today, I’ve finally had enough of squeezing performance out of rotting hardware and simply ordered a new server. Functionally, it will be identical to good old galileo but on beefier hardware, especially with much more RAM (48 GB instead of 12 GB) which is essential for my uses.
While I’m writing this, I’m copying over the entire galileo to the new server which will hopefully be finished in a few hours from now. Once that’s done, I’m going to
- shut down all non-essential services on galileo (that includes Gerrit, Jenkins, the bots and lots of other stuff),
- re-sync the data to the new server,
- change the DNS records,
- fire up all current services on the new server,
(N. B.: Should you think I’ve forgotten something important here, please comment while you still can. :-) )
This update will, thus, cause some downtime (there was some earlier today already when I was preparing the migration). So don’t be alarmed if all services (including my IRC bouncer :-) ) are gone for a while – we’ll be back!
Ideally, you’ll only even read this post when all is over. :-)
