Comment 1 SATHEESARAN 2017-01-11 17:47:20 UTC 
With the conversation with Manoj on the bug 1403772, the computations done for RAID 6 is no different for RAID 5, because gdeploy only looks for 'diskcount', which is the number of data disks.

Thanks sas. So, we will have this in next release.
Comment 4 Sachidananda Urs 2017-02-24 07:45:28 UTC 
Commit: https://github.com/gluster/gdeploy/commit/feceba5 should fix the issue.
Comment 6 SATHEESARAN 2017-04-24 10:00:25 UTC 
Tested with gdeploy-2.0.2-3.el7rhgs
Verified that 'raid5' is accepted as valid disk type by 'gdeploy'.

If illegal RAID type is provided, gdeploy throws proper error message as follows :
"Error: Unsupported disk type!
Only ['raid10', 'raid5', 'raid6', 'jbod'] are supported"
Comment 7 SATHEESARAN 2017-04-24 10:01:08 UTC 
The correct fixed-in-version of this bug is gdeploy-2.0.2-2
