add an option remove-nsm-host #713

Open jeroenmaelbrancke opened 7 years ago

jeroenmaelbrancke commented 7 years ago

Do we have the option to remove a nsm cluster from the abm? You can mark a nsm cluster as lost but what if we want to remove the cluster?

The current installation with framework doesn't support already registered nsm clusters. If we could remove the nsm clusters from the abm this should also help. ticket: https://github.com/openvstorage/framework/issues/1632

@domsj @toolslive is there an option or how hard would it be to implement?

domsj commented 7 years ago

We could implement that an unused nsm cluster could be removed, and I think it should be relatively easy. (The command would give an error in case the nsm host is already in use.) But first: is this actually needed? It seems to me that ops should fix their setup/registration flow?

Fixing the setup/registration flow should be priority numero uno indeed. But since mistakes can always occur, i think such a call could come in handy. Instead of having to re-deploy the entire cluster, they can easily remove the registered NSM

BAM thinks it should always be possible to remove an NSM (even if in use). Since this will take much more time set to Roadmap.
