So, i followed religiously the instructions, whereby i had to create a partition, label it type "8e" (LVM) on the partition. For some reason, back then, i then performed pvcreate on whole device (/dev/sdb, sdc,sdd) and not their partition. It all worked OK for years, even after OS upgrade from Mandrake 10.0 to Mandriva 2006.0, thus changing LVM to LVM2. Until i ran s fresh pvscan was when i broke the configuration. It seems to have been working on cache (/etc/lvm/.cache) configuration, and a pvscan forced a flush of that. > > >and, performed : vgchange -a y > >(it complained of duplicate uuid's, recreated on > >sdb1,sdc1 and sdd1 since pvcreate was complaining > of > >/dev/sdb,sdc & sdd not found!) > pvcreate? did you pvcreate? on the partition? > > >I have been able to mount my reiserfs, so i can > >continue with migration. > >Issue which i have to take up with Mandriva guys is > >why the failure all of a sudden? and do i need to > be > >performing losetup everytime?
