GKE host does not have lvmetad

According to this line:

gluster-containers/CentOS/Dockerfile

Line 62 in c98eefc

VOLUME [ "/run/lvm" ]

we should mount /run/lvm from the host node and not rely on lvm2-lvmetad.service within the container.

Why is that? And also, on GKE neither cos_containerd nor ubuntu_containerd have this service running, so mounting /run/lvm does nothing. How should we proceed in this case?
