hi @aloof-branch-69545 sorry, i didnt pull a bundle when it happened. this time, i was able to get the volume back after shutting off both nodes, then spinning up one of them. i had to mess with the volume in longhorn to spot when it gave me the ability to detach it. also make sure the disks and nodes are in a good service state (i.e. not set to evict volumes, allowing volumes to be scheduled, and not in maint. mode)
if it happens again, i'll document what i did better 🙂 atleast this time i was able to get the volume back, last time i had to resort to destroying it.
