Gunther, the result depends on *how* you copied vg2 over to your new hard drive. If you used for eg. dd to do an image copy of the partitions, which contained vg2 on the flaky drive or a whole disk copy keeping sizes, you've got duplicated content and can unplug the flaky device. If you ran vgscan, you saw your 'old' vg2 in the new drive, which is perfectly fine. BTW: your configuration is a little bit extraordinary in terms of how to use drives as PVs. Typically you shouldn't have multiple VG's on a single drive as you seem to have it. Much rather you should have multiple drives in one VG. > > Thanks for your help! > > Gunther > > > ________________________________________________________________ > Keine verlorenen Lotto-Quittungen, keine vergessenen Gewinne mehr! > Beim WEB.DE Lottoservice: http://tippen2.web.de/?x=13 > > > > _______________________________________________ > linux-lvm mailing list > linux-lvm@sistina.com > http://lists.sistina.com/mailman/listinfo/linux-lvm > read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html -- Regards, Heinz -- The LVM Guy -- *** Software bugs are stupid.
