Thanks! To be honest, I was not aware of global filters. And not aware of using lvmetad, but it is enabled by default (CentOS7). So I added the global_filter and now everything is fine: global_filter = [ "r|/dev/sdb|","r|/dev/sdc|" ] Greetings Christian _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
