But only filesystems. So there's a lot of missing information, that might be relevant to your question once we understand exactly what it is. I'll attempt to answer anyway ... Have a look at the output of 'lsblk -f' to get a comprehensive display of how all your block devices are being used. Also it would be helpful to understand your complete LVM configuration, to see the output of 'vgs', 'pvs' and 'lvs' commands. If your goal is to be able move the /dev/sdb drive between different machines, the easiest way is that it should not be used by LVM at all. That just means it should not participate in any LVM configuration. If that is the situation (and hopefully it is what you have, which the additional information will confirm), then you can simply make a mountpoint inside any of your other /dev filesystems above, and use that mountpoint to mount any filesystem that is on /dev/sdb. Such a mountpoint could be mentioned in /etc/fstab to provide mount configuration including automounting if that is what you want.
