VSAN 6.2 Disk Format Upgrade Fails
I’ve been doing quite a bit of VSAN deployments and upgrades lately. When upgrading up to version 6.1, I did not encounter any issues, luckily. Upgrading VSAN cluster (vSphere) to 6.2 also very smooth; however, upgrading the disk format from version 2 or 2.5 to version 3 has been a daunting task so far. I have an 80% failure rate on this type of upgrade. Here are some of the errors I came across.
