Hi everyone, we just upgraded our 3rd cluster from Longhorn 1.1.1 to 1.2.6 and it went all smoothly. However, we still see some "old" instance-manager pods. We figured that there is 2 instance-managers per Node running which is the case on every updated cluster but there still seems to be some "leftover" of instance managers, they even use the old image. Is this a known issue, can this be somehow resolved?

Is any volume still attached when/after doing the upgrade? Old instance-manager pods might be removed after volume detached.

Yes we did the upgrade online and also Engine Image Upgrade online so some of the volumes were not detached yet
