I’ve been trying for literally years to really get Getting Things Done under my skin. I’ve read the book several times, each time gaining new insights and for a while inching towards actually using it. For some reason, I always fail at it. I’ve never really worked out why. It all makes perfect sense. I believe it’s [...]
..you will need to disable rp_filter on the inbound interface. rp_filter has been enabled by default since Ubuntu 12.04, so even if it worked in earlier versions, you’ll need this setting. You can add an “ip_rp_filter 0” line to the relevant interface in /etc/network/interfaces, and you’re golden.
Erk. I found this sitting around as a draft: Today’s normality is tomorrow’s abnormality Last time, we looked at a disk usage graph. This week, we’ll look at CPU usage or something else that goes up and down instead of just up, up, up. What’s the problem here? The problem is that it’s very hard [...]
I took much longer to post this than intended. Not that I expect anyone to have been sitting on the edge of their chair waiting for it, but still… It’s been more than month since my last post, and not a darned thing has changed. Monitoring today still sucks. In the last installment I ranted [...]
Monitoring today sucks. Big time. It sucks so bad, it’s not even funny. The amount of time spent configuring stuff, dealing with problems when it’s already too late, and the amount of things your monitoring system could be monitoring, but isn’t, are all staggering. I’ll be spending a couple of posts whining about this. Who [...]
Seeing as the election for the OpenStack Project Policy Board is going on, it seems only fair to announce that I quite soon no longer will be working for Rackspace. Instead, I will be working (still on OpenStack) for Nebula. If this is material to your vote, I apologise for not disclosing this earlier, but [...]
I’d like to take a couple of minutes of your time to talk about testing of OpenStack. Swift has always had very good test coverage, and Glance also does pretty well, so I’ll mostly be focused on Nova. (Psst… If you can’t be bothered to read the whole thing, just skip down to the how [...]
We use PPA’s quite heavily in OpenStack. Each of the core projects have a trunk PPA and a milestone-proposed PPA. Every commit to our bzr trunk branch results in an upload to the trunk PPA, and every commit to our milestone-proposed bzr branch results in an upload to (you guessed it) the milestone-proposed PPA. Additionally, [...]
—–BEGIN PGP SIGNED MESSAGE—– Hash: SHA512 (Thanks to Colin Watson for the template for this post) I’ve finally gotten around to setting up a new, strong (4096 bit) RSA- based GPG-key, and will be transitioning away from my old 1024 bit DSA key. The old key will continue to be valid for some time, but [...]
I got good feedback on last week’s post about the stuff I’d achieved in Openstack, so I figured I’d do the same this week. We left the hero of our tale (that would be me (it’s my blog, I can entitle myself however I please)) last Friday somewhat bleary eyed, hacking on a mountall patch [...]
