If some lvm1 device is missing, lvm fails on all operations # vgcfgbackup -f bck -P vg_test Partial mode. Incomplete volume groups will be activated read-only. 3 PV(s) found for VG vg_test: expected 4 PV segment VG free_count mismatch: 152599 != 228909 PV segment VG extent_count mismatch: 152600 != 228910 Internal error: PV segments corrupted in vg_test. Volume group "vg_test" not found Allow loading of lvm1 partial VG by allocating "new" missing PV, which covers lost space. Also this fake mising PV inform code that it is partial VG. https://bugzilla.redhat.com/show_bug.cgi?id=501390
