MapR installation on centos is erroring

I am trying to install MapR using MapR installer. I chose the disks it suggested in verification tab for each node. The disks are /dev/mapper/centos-pool00_tmeta & /dev/mapper/centos-pool00_tdata

I can navigate to installation tab. There it shows "installing" for 20 minutes and then errors with the below message. Any help is highly appreciated.

2017-04-04 20:43:00.740:  failed: [fail msg="Failed to format {{ mapr.node.disks|join(',') }} for MapR-FS. Review {{ mapr_home }}/logs/disksetup.0.log, address the reported issues and retry installation"] [10.10.110.179] => {"failed": true}
Failed to format /dev/mapper/centos-pool00_tmeta,/dev/mapper/centos-pool00_tdata for MapR-FS. Review /opt/mapr/logs/disksetup.0.log, address the reported issues and retry installation

disksetup.0.log

I have re run the installation and I see this error now in disk log. ExitDiskSetup:210 ERROR /dev/mapper/centos-pool00_tmeta failed. Error 16, Device or resource busy. Disk is used by some other module/process.[' File "/opt/mapr/server/disksetup", line 1398, in \n RunDiskSetup();\n', ' File "/opt/mapr/server/disksetup", line 1277, in RunDiskSetup\n InitAllDisk(force);\n', ' File "/opt/mapr/server/disksetup", line 649, in InitAllDisk\n disk.InitDevices(forceOption);\n', ' File "/opt/mapr/server/disksetup", line 513, in InitDevices\n InitDisk(dev, forceOption);\n', ' File "/opt/mapr/server/disksetup", line 372, in InitDisk\n AbortWithError(rc, errMsg, devicePath);\n', ' File "/opt/mapr/server/disksetup", line 240, in AbortWithError\n stack_trace = traceback.format_stack(frame)\n']

According to Lars' investigation, there is only one real disk - /dev/sda.   In order to install, you need to either add a disk or create another logical volume in the Centos volume group that you tell the installer to use. Please see the reason for adding a disk or creating another logical volume in the Centos volume group.
