Issue

• My original lvm filter defined in /etc/lvm/lvm.conf was:

filter = [ "a/.*/" ]

• Using that filter I had the following vgs output:

$ vgs -v 
    Finding all volume groups
    Finding volume group "rootvg"
  VG     Attr   Ext    #PV #LV #SN VSize  VFree VG UUID                               
  root_vg wz--n- 32.00M   1  10   0 19.88G 6.59G A120aA-770a-9AaA-7aa4-aaaa-AAa1-A2312A

• Then I changed it to the filter bellow and my VG dissapeared:

filter = [ "a|/dev/sda2$|", "a|/dev/sdb2$|", "a|/dev/mapper/mpath.*|", "r|.*|" ]

• And my VG dissapeared and I received the following vgs output :

$ vgs -v 
  WARNING: Ignoring duplicate config node: filter (seeking filter)
    Finding all volume groups
    Finding volume group "vg_test"
    Finding volume group "rootvg"

• What can I do to have access to my VG again?
