OL 7.2 LVM pvcreate Device /dev/sdxx not found (or ignored by filtering).

Hi,

I'm having problems trying to create a physical volume. This is my scenario.

I have configured this layout:

pvscan

  PV /dev/sdg1   VG REDO01       lvm2 [10.00 GiB / 0    free]

  PV /dev/sdf1   VG ORAFRA       lvm2 [75.00 GiB / 0    free]

  PV /dev/sdi1   VG ORAFRA       lvm2 [10.00 GiB / 10.00 GiB free]

  PV /dev/sdb1   VG SYSTEM       lvm2 [49.99 GiB / 0    free]

  PV /dev/sdd1   VG ORADATA      lvm2 [150.00 GiB / 0    free]

  PV /dev/sde1   VG ORABACKUP    lvm2 [50.00 GiB / 0    free]

  PV /dev/sdc1   VG ORAINSTALL   lvm2 [20.00 GiB / 0    free]

  PV /dev/sdh1   VG REDO02       lvm2 [10.00 GiB / 0    free]

  Total: 8 [374.96 GiB] / in use: 8 [374.96 GiB] / in no VG: 0 [0   ]

now if I want to expand ORAFRA, the plan is to expand /dev/sdf hard drive, and to create one more partition on  it:

fdisk -l /dev/sdf

Disk /dev/sdf: 107.4 GB, 107374182400 bytes, 209715200 sectors

Units = sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk label type: dos

Disk identifier: 0x05a34f6a

   Device Boot      Start         End      Blocks   Id  System

/dev/sdf1            2048   157286399    78642176   83  Linux

/dev/sdf2       157286400   209715199    26214400    5  Extended

i have also tried to configure /dev/sdf2 as "8e" (Linux LVM type). In both cases (extended and Linux LVM) I get the same when trying to create a new physical volume:

pvcreate /dev/sdf2

Device /dev/sdf2 not found (or ignored by filtering).

I have also tried to change filter setting in /etc/lvm/lvm.conf. Didn't help.

Adding a new Hard Disk and creating a new partition on it allows me to create a new physical volume. I did is with /dev/sdi, and than expanded VG ORAFRA.

The problem seems to happen only if I use multiple partitions on the same hard drive. The Server is running as a VM on VMware.

Any idea how to fix this issue?
