I'm not sure about the helm installatioin. I've never ran anything custom on this cluster and I'm not the most familiar with harvester. I ran the pre-check upgrade command and and they came back with all passes. The only addon I enabled was the rancher monitoring and the pci devices addon. I am totally guessing here also, and mine are completely uneducated guesses, but I think it didn't clean some stuff up from the last upgrade. The hvst-upgrade-xxxx did correspond to the previous upgrade I did to 1.2.1 a while ago. Or so I think it was the same, I can't be for sure, all i can remember from that upgrade is that when it was setting things up and I happened to glance at longhorn I saw a volume that had the hvst-upgrade-x and the x was the same number.
