Maybe you will be confronted one day with this strange issue. this happens when you trying to create a physical volume from a normal disk of from multipath
When trying to create a physical volume .
pvcreate /dev/mapper/oracle Device /dev/mapper/oracle excluded by a filter.
- This issue may arise if the disk was already used or it has a partition table information on it.
- It is possible that the disk was used earlier with any other system.
- GPT disk label has been created earlier.
The Solution is :
you can wipe out the old partition information with “wipefs”
# wipefs -a /dev/mapper/oracle /dev/mapper/oracle: 8 bytes were erased at offset 0x00000200 (gpt): 45 46 49 20 50 41 52 54 /dev/mapper/oracle: 8 bytes were erased at offset 0x18fffffe00 (gpt): 45 46 49 20 50 41 52 54 /dev/mapper/oracle: 2 bytes were erased at offset 0x000001fe (PMBR): 55 aa /dev/mapper/oracle: calling ioclt to re-read partition table: Invalid argument
]# pvcreate /dev/mapper/oracle Physical volume "/dev/mapper/oracle" successfully created.
Voila. Your problem is solved now.
