If you want to activate "bigspace" just in order to backup date *and* remove/recreate it afterwards, you might want to use the following workaround: o identify your actual metadata backup (say, bigspace.conf) o mkdir /etc/lvmtab.d o cp bigspace.conf /etc/lvmtab.d/bigspace o echo -ne "bigspace\0" > /etc/lvmtab o vgchange -ay > > My guess now is to make a new vg and add those disks... but I want to be > sure, so I don't lose the data. That won't work, because the PVs are falgged *new* after pvcreate -ff and you will just have empty PVs that way. > > Any suggestions to recover the data or to replace the broken harddisk > with a new one with as little data loss as possible. > > Regards, > Thomas. > > _______________________________________________ > 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/ -- Regards, Heinz -- The LVM Guy -- *** Software bugs are stupid.
