Why am I getting inconsistent/conflicting pictures of the DATA partitions that were created in the CentOS 7 installation process when I use df -T -h, parted  ...  print, and fdisk -l?  In case it matters, used xfs file system because that was the default.The Background of the process is:  During a recent installation of CentOS 7, I chose Manual Partitioning in the Installation Destination part of the process.  The tutorial in this link contains screen shots illustrating the installation process, and the screen in the process where the DATA partitions are created is shown below (from the same tutorial).http://www.tecmint.com/wp-content/uploads/2014/07/CentOS-7-Installation-16-600x450.pngIn the above screen shot, my installation wizard automatically created a /home DATA partition.  I shrunk the auto-created /home partition, and created four new 300 GB DATA partitions called /public, /vpn, /data, and /test using the screen shown in the screen shot, and I then completed the installation.df -T -h results: In the resulting installation, typing df -T -h results in:  [root@localhost ~]# df -T -hFilesystem              Type      Size  Used Avail Use% Mounted on/dev/mapper/centos-root xfs        50G 1016M   49G   2% /devtmpfs                devtmpfs  3.8G     0  3.8G   0% /devtmpfs                   tmpfs     3.8G     0  3.8G   0% /dev/shmtmpfs                   tmpfs     3.8G   17M  3.8G   1% /runtmpfs                   tmpfs     3.8G     0  3.8G   0% /sys/fs/cgroup/dev/sda2               xfs       494M  139M  355M  29% /boot/dev/mapper/centos-home xfs       605G   33M  605G   1% /home/dev/sda1               vfat      200M  9.8M  191M   5% /boot/efi/dev/mapper/centos-01   xfs       280G   33M  280G   1% /public/dev/mapper/centos-02   xfs       280G   33M  280G   1% /data/dev/mapper/centos-03   xfs       280G   33M  280G   1% /test/dev/mapper/centos-00   xfs       280G   33M  280G   1% /vpn**parted ... quit results:  However, parted does not seem to see the four new DATA partitions, as shown below:  [root@localhost ~]# partedGNU Parted 3.1Using /dev/sdaWelcome to GNU Parted!

why are DATA partitions not consistently reported in CentOS 7?

It appears you chose to use logical volumes (LVM) rather than partitions.  These are not partitions, and are managed using a different mechanism.  Try using an LVM command like sudo lvm lvs.  This should list the logical volumes.
