'virsh vol-create-as' command shows error: Storage volume not found

Issue

• We are trying to use the steps in 16.2. Creating volumes to create a disk based storage pool, and volume, but virsh vol-create-as command fails with below error:

  [root@host1 xml]# virsh vol-create-as satellite-disk satellite-vol 500G
  error: Failed to create vol satellite-vol
  error: Storage volume not found: no storage vol with matching path '/dev/mapper/mpathap1'
  

  It looks that multipath had created a partition with name /dev/mapper/mpatha1, instead of /dev/mapper/mpathap1 which caused this failure:

  [root@host1 xml]# ls -l /dev/mapper/mpatha*
  lrwxrwxrwx 1 root root 7 Sep 10 17:39 /dev/mapper/mpatha -> ../dm-3
  lrwxrwxrwx 1 root root 7 Sep 10 17:39 /dev/mapper/mpatha1 -> ../dm-8
  

• libvirt not naming new volumes correctly
