[linux-lvm] pvscan: /dev/sdc: open failed: No medium found

[Gang He]

Hello Peter and David,

Thank for your quick responses.
How do we handle this behavior further?
Fix it as an issue, filter this kind of disk silently. 
or keep the current error message printing, looking a bit unfriendly, but the logic is not wrong.


Thanks
Gang
