Any chance the FS containing /etc/lvm is mounted read-only? If so it may fail. There is a bug as no error is reported in that situation. See backup section of lvm.conf - set backup and archive to point to a writable FS. If not, could you send a tarball with /etc/lvm: `tar czf lvmdump-etc /etc/lvm/` Joining us on IRC: #lvm @ freenode guarantees faster answers. -- Marian > > > _______________________________________________ > 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/
