This comment from Zdenek Kabelac 'closes' this bug report as far as I'm concerned:
Hmm you are doing snapshot of 'root' filesystem - and there could be actually some problems with delivering of cookie since udev might get frozen.
So folks, don't do: lvcreate -s ... &>/file/on/rootfs But instead do: out=$(lvcreate -s ... 2>&1); echo "$out" >/file/on/rootfs
