+ + tl;dr - I over-engineered a script to run a small experiment to figure out what was the right cluster size for PM2 in various CPU + RAM configurations. Turns out having lots of PM2 instances is really good when there’s not much memory and only slightly bad when there is sufficient memory, so a blanket recommendation like 32 actually works out. The code is on Gitlab – you can skip to the results.| vadosware.io

+ / / tl;dr - I did another round of drive testing (originally I only tested OpenEBS and hostPath), this time with some rented Hetzner machines and Ansible-powered automation. The GitLab repository isn’t ready for mass consumption yet but I’ll update here (and this tl;dr) when it is, along with the results. UPDATE (04/09/2020) The GitLab repository is up! You can skip this entire article and just go there. NOTE: This a multi-part blog-post!| vadosware.io

+ / / tl;dr - In order to test storage performance I set up a completely automated test bed for all the storage plugins, this article chronicles the installations of some of the plugins. It’s particularly long because I made lots of mistakes. Mostly useless sections are prefaced with a notice on why you can skip them, skim the ToC and click on anything you like.

+ / / tl;dr - I install even more providers, this time OpenEBS cStor, OpenEBS Jiva, OpenEBS LocalPV hostPath, and OpenEBS LocalPV ZFS, LINSTOR via kvaps/kube-linstor. I skipped OpenEBS LocalPV because it threw a panic linked to a supposed kernel issue complaining about old kernels. Ain’t nobody got time for that. The GitLab Repo is finally public though, so you could skip this entire article and go there. UPDATE (04/10/2021) I had some more issues with linstor than I thought -- I've updated...| vadosware.io

+ / / tl;dr - I explain the YAML and Makefile scripts that power the fio and pgbench (oltpbench) tests I’m going to run. UPDATE (04/10/2021) Turns out I was mistaken -- OpenEBS Mayastor doesn't support single-node disk-level failure domains. It's very well described on their website in the FAQ, but I somehow missed and/or forgot that, so the tests for Mayastor will only represent JBOD setup (no replication). On a different but related note, cStor supports cross disk replication (mirroring o...| vadosware.io
