Jonathan, thanks for the reply. I fixed the problem with 'pvcreate' & 'vgcfgrestore'. The real problem sat in front of the keyboard (as always :) ). I missed an argument for pvcreate. I didn't specify my physicalvolume, instead I put my vgname 'alice' instead of /dev/loop as an argument. After that, I run vgcfgrestore and everything is fine again :) Ralf > On Wed, 2009-01-07 at 14:43 -0600, Jonathan Brassow wrote: > Could you do a 'pvscan -vvvv' and post (attach) the output? > > You could also copy the first several MB of the PVs that compose > "alice".
