most modern desktops will offer a tool to react when disk (usb) is plugged
in and if encrypted ask for password to decrypt. IF there is lvm they will
handle the lvm automatically

Manually it can be done as follows (presumably the disk was encrypted with

1. plugin in / connect the usb to the computer
2. cryptsetup luksOpen /dev/sd<x>1 cryptedDisk
3. vgchange -ay cryptedDisk
4. mount /dev/mapper/cryptedDisk-<logical volume> ...


1. umount /dev/mapper/cryptedDisk-<logical volume>
2. vgchange -an cryptedDisk
3. cryptsetup luksClose cryptedDisk
4. unplug

* <x> - disk id (a,b,c,d etc)
* <logical volume> - volume name
