@tcoupin thanks for reporting the issue! Granted, I didn't give this much thought, but an argument can be made that it is useful to see it twice to see all the pods that a volume is mounted to. So maybe it's a feature, not a bug? What do you think? What's your usecase?

[tcoupin]

imho, this tool is to view space of PV so I guess only one line by pv. Perhaps you can join all pod names per pv

I agree with @tcoupin it will be nice to focus PV, maybe it can deduplicate same PV's.
Thanks
