Hmmm. I've not seen vgexport/vgimport mentioned. Will this be needed?

If your wanting to add a new disk to the same volume group and use it then no you don't need to rename anything, you can use the vgextend command after running pvcreate on the new disk to extend the existing volume group to the new disk. If your wanting to add an existing disk to a system that already has a conflicting volume group name in it, then yes you'll need to vgrename one of them so they do not conflict. nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Yes.

[CentOS] can I use 2 HDD's with the same LVM labels at the same time?
Hi all, I need to add a drive with the same LVM labels (i.e. system) to a machine with a drive with the same label. How can I access the data on both drive's LVM partitions at the same time? -- Kind Regards Rudi Ahlers ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
