Activating LVM volumes after failure to attach after reboot

I currently have the problem that after every reboot the two external hard disks (both connected via USB) throw the error "Activating LVM volumes after failure to attach ...".Normally I can then reactivate them as described here

Here briefly as an example for sdbthin

lvchange -an sdbthin/sdbthin_tmetalvchange -an sdbthin/sdbthin_tdatavgchange -ay

Is there a way to avoid this? for example

• clean shutdown before reboot
• clean mount after reboot

Not sure where to start!

Many thanks
