[linux-lvm] LVM snapshot with Clustered VG

[Andreas Pflug]

Hi Vladislav,

I tried the patch you mentioned in 
https://www.redhat.com/archives/linux-lvm/2013-January/msg00006.html , 
but apparently it doesn't work for me. On a locally active LV, I still get

./lvm lvchange -aey -vvvv vg/locktest

...
Activating logical volume "locktest" exclusively
#activate/dev_manager.c:284         Getting device info for vg-locktest

Can you give me a hint what to try further?
