DIY Fault‑Tolerant Microcluster

on YouTube ↗40m

" summary

Describes how to build a fault-tolerant microcluster using minimal hardware: L2 topology for component interconnects and L3 setup (HSRP, corosync) for external service availability. Covers local HA block storage with DRBD in dual-primary mode, OCFS2 on top of DRBD, running and maintaining virtual machines in the microcluster, plus limitations and common problems with fixes.
