[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

Use vgrename on one of them. -- Ignacio Vazquez-Abrams <ivazqueznet at gmail.com> PLEASE don't CC me; I'm already subscribed -------------- next part -------------- A non-text attachment was scrubbed...

So, do I rename System with vgrename then? -- Kind Regards Rudi Ahlers
