Hello List,

One user complained this error message.
The user has a usb sd card reader with no media present.  When they issue a pvscan under lvm2-2.02.180 the device is opened which results in 'No medium found' being reported. 
But lvm2-2.02.120 did not do this (the device appears to get filtered out earlier). The customer views the 'No medium found' message as an issue/bug.
Any suggest/comments for this error message?

The detailed information is as below,
lvm2 2.02.180-9.4.2
Kernel 4.12.14-95.3-default
Hardware: HP ProLiant DL380 Gen10

After upgrade from sles12SP3 to SP4, customer is reporting the following error message:

 # pvscan
