Any idea to remove vg?

You cannot use --removemissing or force delete VG if metadata area equal zero as in my case.

Make block device from file and include in $VG:

dd if=/dev/zero of=/tmp/tmp.raw bs=1M count=100
losetup -f
losetup /dev/loop0 /tmp/tmp.raw
vgextend $VG /dev/loop0

After that I have Metadata Areas 1

vgremove --force $VG

and remove pvdevice:

pvremove /dev/loop0

    vgremove takes the --force or -f flag before the VG name

Run vgreduce --removemissing $VG first. This will remove all "partial" LVs - that's any LVs using the missing disk. Man: vgreduce(8).
