LVM setup on vProtect Node for disk attachment backup mode
Note: this is required for Nutanix and RHV v4 API (when using disk attachment mode)
vProtect Node attaches VM disks that potentially are clones of its own (i.e. if Node deployed from the template) - you need to configure LVM on the Node so that it doesn't scan for LVM volumes where disks are being attached.
  1. 1.
    Set the following variables in /etc/lvm/lvm.conf - so that only system volumes are being detected by LVM daemon (in this example /dev/sda1):
    filter = [ "a|^/dev/sda1$|", "r|.*|" ]
    global_filter = [ "a|^/dev/sda1$|", "r|.*|" ]
  2. 2.
    Check with vgscan -vvv that your OS volumes are still being detected:
    Allocated VG vg_vprotect at 0x55914f19fac0.
    Importing logical volume vg_vprotect/lv_root.
    Importing logical volume vg_vprotect/lv_swap.
  3. 3.
