How to replace a failed server in a 2-node vSAN cluster

[Brainbugg]

Hi There

What steps must be followed to rebuild and replace a failed host in a 2-node (ROBO) vSAN cluster if ESXi needs to be rebuilt and should the disks that are part of the vSAN cluster be deleted before joining the cluster again?

In addition to above what steps must be followed to rebuild the fault domain configuration?

Do the steps differ for a vSAN 6.6 and 6.7 cluster?

I followed the steps in the article below but this doesn't seem to work and when I add the server back, it doesn't join the existing vSAN cluster but instead creates a new Cluster consisting of only 1 node.

In the same manner as noted in the other post you made - please refrain from making multiple posts for what is essentially the same question, this only makes it less easy for people to find useful answers.

Yes you should configure Fault Domins correctly though, I'll aim to update that KB accordingly (and with the other vC part I noted, which I could have sworn it already included). Did you manage to get your node re-clustered okay following the KB steps as opposed to the blog steps?
