Hi all,
Just a friendly reminder that we're taking down Gerrit in about 30
minutes for a planned
migration to a new (bigger) server. We've allotted an hour for the
changeover but I'm not
expecting it to take that long.
I'll be sure to let everyone know when it's back up and running.
We're all squared away on the new box. As always let me know if
you run into any problems.
So I wanted to explain a bit more what we did today and why. We
moved Gerrit off of its old server of manganese to a new box of
ytterbium. Other than an IP address change (208.80.154.152 to
208.80.154.81), you shouldn't notice much of a difference at first.
We did this for a couple of reasons. Manganese has been a very
stable box but lacks the resources we need for an ever-growing
Gerrit installation. The new server has a lot more RAM and CPU
cores, all 100% dedicated to running Gerrit. As time goes on, I'm
sure we'll find ways to further tweak the Gerrit config to make use
of our new hardware. The IP address change is also notable--
we've changed the setup to make it easier for us to eventually
implement a long-standing request of removing port 29418 from
Gerrit operations over SSH (no timeline on that just yet).
As you may have noticed, I've not been doing much with Gerrit
these days--my efforts have focused on HTTPS and Search. I
just wanted to let everyone know that I still care about giving
everyone a fast and stable Gerrit environment :)
