I'm trying to mount my old 2x500GB drives to the new server which has the same drive volume. Both have LVM structure but it's not working.root@server [/mnt/usb]# ls /dev/sd*  /dev/sda   /dev/sda2  /dev/sdb1  /dev/sdc1  /dev/sdd1  /dev/sde  /dev/sda1  /dev/sdb   /dev/sdc   /dev/sdd   /dev/sdd2  /dev/sde1  aroot@server [/mnt/usb]# pvscan    Couldn't find device with uuid 72VbNB-nT9K-DR4f-X39N-UsY6-LdIl-gJrYMp.
