Re: [linux-lvm] problem



Procedure to follow:
  
   vgcfgbackup -P -f /tmp/vgbackup rootvg

   Edit the backup file as follows:
   Add "WRITE" to the status line and remove "PARTIAL"

e.g.
   status = ["RESIZEABLE", "PARTIAL", "READ"]
becomes
   status = ["RESIZEABLE", "READ", "WRITE"]


Remove the whole PV section for your "unknown device"
- referenced as "pv1" in this example.

                pv1 {
                        id = "TBCgjx-ne5X-4fHP-aHqe-dKJR-Vwnb-kjDhWQ"
                        device = "unknown device"       # Hint only

                        status = ["ALLOCATABLE"]
                        pe_start = 128
                        pe_count = 5    # 20 Megabytes
                }


Remove the whole LV section for any LVs that refer to the pv you
removed above (pv1 here referenced inside "stripes") e.g.

                tmp {
                        id = "4eTLYv-PTDr-FXvv-58Xk-Q4Th-p8yi-GeKCHr"
                        status = ["READ", "WRITE", "VISIBLE"]
                        segment_count = 1

                        segment1 {
                                start_extent = 0
                                extent_count = 3        # 12 Megabytes

                                type = "striped"
                                stripe_count = 1        # linear

                                stripes = [
                                        "pv1", 0
                                ]
                        }
                }

Write the metadata back to disk:
  vgcfgrestore -f /tmp/vgbackup rootvg
