Dear All,

I am trying to build a new linux VM using RHEL6.2. I have created the
partitions using lvm. Everything works fine, but when I execute "fdisk -l"
I am getting the below errors. Is this expected? If so, how to fix the
errors?

Disk /dev/mapper/vg00-root doesn't contain a valid partition table
Disk /dev/mapper/vg00-opt doesn't contain a valid partition table
Disk /dev/mapper/vg00-tmp doesn't contain a valid partition table
Disk /dev/mapper/vg00-var doesn't contain a valid partition table
Disk /dev/mapper/vg00-usr doesn't contain a valid partition table
Disk /dev/mapper/vg00-home doesn't contain a valid partition table

Complete output of fdisk -l is given below:

This is to be expected. because it is possible to have partition tables on
logical volumes created by LVM. if you don't like this use the "filter"
line in /etc/lvm/lvm.conf to include/exclude what you want to be searched.
This is also useful if you want to exclude multipathed/mirrored devices.

fdisk is just scanning everything that it finds in /proc/partitions:

/*
 * for fdisk -l:
 * try all things in /proc/partitions that look like a full disk
 */
static void
print_all_partition_table_from_option(unsigned long sector_size)

This doesn't use the LVM2 filters so will continue to report for all
device-mapper devices when using '-l'.

Bryn.
