Error: pvcreate: Device /dev/mapper/software01p1 not found

When trying to run pvcreate on a partition that exists on the system, it says that device is not found.

root@linux:/ # pvcreate /dev/mapper/software01p1
Device /dev/mapper/software01p1 not found.

The device exists on the system

root@linux:/ # ls -l /dev/mapper/software01*
brw——- 1 root root 253, 7 Jul 27 10:23 /dev/mapper/software01
brw——- 1 root root 253, 8 Jul 27 10:27 /dev/mapper/software01p1

The problem was that the LVM filter is not configured to consider it as a valid device.

Edit the file /etc/lvm/lvm.conf and edit the parameter filter accordingly. I used the filter below:

root@linux:/ # vi /etc/lvm/lvm.conf
filter = [ “a|cciss/.*|” “a|/dev/mapper/.*|”, “r|/dev/sd.*|”, “r|/dev/dm-.*|” ]
