Hi, I'm unable to create PVs on Multipath-Volumes that are available at /dev/dm-NN where N~[0-9] but I can create them on single digit devices like /dev/dm-9: # pvcreate /dev/dm-6 Physical volume "/dev/dm-6" successfully created. # pvcreate /dev/dm-16 Device /dev/dm-16 not found (or ignored by filtering). My Version of LVM is 2.02.168 from Debian 9. The filter ist set to a permissive value: filter = [ "a|.*|" ] global_filter = [ "a|.*|" ] Any ideas why two or more digits in the device path can cause it to be filtered by pvcreate?
