These are valid points. I’ve personally needed to do things like delete the StatefulSet, change volume size, update/change pvc, update StatefulSet, reapply. I just took it as a given and hadn’t thought much about the ergonomics.

It’s really not that big of a deal and probably a ten minute process, tops. That said, OP makes a good point that mechanisms to handle this kind of stuff exist in CSI, so why not leverage / take advantage of that versus pissing in the wind (especially when you run into CRD that wants to undo the above work while you’re in the process)?
