For using LVM in Kubernetes, why not toplvm? https://github.com/topolvm/topolvm The design looks right, running lvm commands on the host: https://github.com/topolvm/topolvm/blob/main/docs/design.md Nir _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://listman.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
