Hi,
sorry but it did not work:
I deactivate the VG kvm_disk0 with vgchange -an kvm_disk0, after that I set the filter and do a update-initramfs -u -k all
But after reboot the VG is always activate.
...
kvm_disk0 data -wi-ao 400.00g
vm-203-disk-1 kvm_disk0 -wi-a- 28.01g
vm-203-disk-2 kvm_disk0 -wi-a- 80.00g
...
Regards,
Erik

OK, you're using an older LVM2/device-mapper that does not use udev to
manage the device nodes and symlinks in /dev.

Yes. Or use the alternate style I showed and only accept the PVs
belonging to the data VG.
As Lars said you may also need to rebuild your initramfs although if the
data VG doesn't contain your root file system, swap or other resources
normally set up in the initramfs this shouldn't be needed.

Bryn.
