>>> 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
>>> <http://platinum_02336-1600706364.vg> platinum
>>>

>> Without having access to your current metadata - it's hard to give

>> So please attach  'vgcfgbackup' of your current setup.

>> Have you tried to 'extend' your existing vg   'plt' with referencing LVs

>> Is 'plt' VG ?
