I've just gone through this, so this would be for the next time. I have two drives in my ds218j. A 16TB data drive and a 4TB 'system' drive that has DSM on it.

After much troubleshooting, it was determined the DSM on the 4TB was corrupted. System would boot up, but I would never see DSM from the app or the web.

I replaced the 4TB, boot up and it reinstalled DSM. All is good. But I could not figure out how to introduce the 16TB drive without a format. Is there a guideline or something I should follow so I don't lose all the data on a perfectly good drive?

This is the one that is populated with all battery powered devices. I have migrated from zha to z2m, so of course none of the entities are valid.

Anyone know how to recreate the dashboard?
