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?
