These LVs all have active kpartx mappings (the names with pN
suffixes). Remove them with kpartx -d:

# kpartx -d /dev/mapper/vg_vhost01-lv_vm_base
# kpartx -d /dev/mapper/vg_vhost01-lv_vm_pas.harte--lyne.ca
# kpartx -d /dev/mapper/vg_vhost01-lv_vm_pas.harte--lyne.ca_01
# kpartx -d /dev/mapper/vg_vhost01-lv_vm_pgsql--dbms.harte--lyne.ca_00
# kpartx -d /dev/mapper/vg_vhost01-lv_vm_pgsql--dbms.harte--lyne.ca_01

Bryn.
