Unable to access a newly created partition on Red Hat Enterprise Linux 6

Solution Verified - Updated -

Issue

  • We attempted to create a new partition to a system volume by using the parted command.  However, the parted command reported the following error.

        # parted -s /dev/sda mkpart primary 44502MiB 100000MiB
        Warning: WARNING: the kernel failed to re-read the partition table on /dev/sda (Device or resource busy).  As a result, it may not reflect all of your changes until after reboot.
    
  • Using fdisk to create a new partition results warning messages (same messages as above)

  • Using partprobe to add newly created partitions worked in RHEL5 but now only print out the above warning message

  • Modifying a disk's partition table using parted to add, remove or resize partitions fails to create /dev entries.

  • Attempting to use partprobe to refresh the partition table information known by the kernel fails.

  • partprobe command fails to reread the partition table

  • How do we add newly created disk partitions on RHEL6?

Environment

  • Red Hat Enterprise Linux 6 (RHEL6)
  • parted v2.1
