02/11/2023, 3:00 AMDo you setup etcd in multiple nodes? If yes, I think this case might same as this Issue#1755 .

02/11/2023, 6:39 PM@narrow-egg-98197 yes. it's harvester cluster with 6 nodes. one of the nodes is etcd member, one is not.
can i just delete the pvc without losing the data? i guess that's my worry is if i delete the pvc, the data would be lost. sounds like that's the work around though.
@narrow-egg-98197 i've looked at that, i cant find anything mounting that pvc. i cant figure out how to "detach it" it's not an option available in the ui.
i've shut off one node that was running the instance-manager, and i killed the pod on the other server, and it still wont release.

02/14/2023, 4:20 PMwith a little guidance, yes. not sure how to back up the pvc, and i just use dd and give it the path of the pvc, and the path of a new pvc that's blank? just like if i were cloning a disk or partition.
also, a harvester team member was also helping w/ this. he said this yesterday, do you maybe know the answer? he hasnt gotten back to me yet.
