[linux-lvm] Volume group inconsistent

[Marcos Dutra]

Hi everybody,

Yesterday some storage discs of my VG was with missing status
/dev/mapper/plt-01                                        platinum
lvm2 a-m  500.00g   24.95g
  /dev/mapper/plt-02                                        platinum
lvm2 a-m  500.00g   12.93g

I tried recover the discs and I used the command:
# vgextend --restoremissing platinum /dev/mapper/plt-01

It worked, removing missing status, but I did a big mistake, i tried to run
this command with multiple discs:
# vgextend --restoremissing platinum /dev/mapper/plt-0[2-9]

After that when I ran pvs command the output shows me checksum error:
  /dev/mapper/plt-04: Checksum error
  /dev/mapper/plt-06: Checksum error
  /dev/mapper/plt-01: Checksum error
  Couldn't read volume group metadata.
  /dev/mapper/plt-02: Checksum error
  Couldn't read volume group metadata.
  /dev/mapper/plt-03: Checksum error

I tried restore metadata without success:
# vgcfgrestore -f platinum_02336-1600706364.vg platinum
  /dev/mapper/plt-03: Checksum error
  /dev/mapper/plt-22: Checksum error
  /dev/mapper/plt-19: Checksum error
  /dev/mapper/plt-16: Checksum error
  /dev/mapper/plt-13: Checksum error
  /dev/mapper/plt-11: Checksum error
  /dev/mapper/plt-09: Checksum error
  /dev/mapper/plt-07: Checksum error
  /dev/mapper/plt-01: Checksum error
  /dev/mapper/plt-05: Checksum error
  /dev/mapper/plt-25: Checksum error
  /dev/mapper/plt-23: Checksum error

  /dev/mapper/plt-14: Checksum error
  /dev/mapper/plt-02: Checksum error

  /dev/mapper/plt-10: Checksum error
  /dev/mapper/plt-08: Checksum error
  /dev/mapper/plt-04: Checksum error
  /dev/mapper/plt-06: Checksum error
  Cannot restore Volume Group platinum with 24 PVs marked as missing.
  Restore failed.

Thanks for help me.
