  • The agony of NFS for 25+ years of my life! Then and now. ClearCase and Kubernetes

    The agony of NFS for 25+ years of my life! Then and now. ClearCase and Kubernetes

    My first experiences with NFS (Network File System) started in 1989. My first term at university, a set of vax machines running BSD Unix, some vt220 terminals, and ‘rn’. My first understanding of NFS came a few years later. ClearCase. I was working at HP, the year was 1992. Most of us on the team…

    Hack or Genius: cloud backup revisited

    So earlier I wrote about my simple rsync approach. It worked well for a bit, and then mysteriously broke. Why you ask? And how did I fix it? Well, down the rabbit-hole we go.

    So the home OpenStack system is running Queens on Ubuntu 18.04, courtesy of Kolla. Great. The all-NVME Ceph I talked about in the previous post is kicking ass and taking names for glance/nova/cinder. Now, lets try some container orchestration and install Kubernetes via Magnum. Make sure to use Fedora-Atomic and not coreos because of this. But also…

  • Hack or genuis: cloud backup, you vote!

    OK, you read from my previous post that I’ve tooled up some things in public cloud (specifically Google GCP & GKE). Now, I’m sure they have a strong track record of backup/restore/disaster recovery. But what if… something goes wrong. Maybe I make a mistake and delete the project, my credit card gets stolen and they…
