But, this is one place printing a warning about it. I'll remove the warning. Run 'pvs', and check if /run/lvm/hints exists.

The machine needs to have a system ID configured. See lvmsysystemid(7) and edit lvm.conf/lvmlocal.conf. Then vgcreate will use the machine's system for the new VG. Using --systemid overrides the local value which you don't want. _______________________________________________ linux-lvm mailing list linux-lvm@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
