Description bipin 2018-02-21 13:11:26 UTC 
Description of problem:

In the cockpit UI, during the Gluster storage deployment while checking the enable Dedupe and Compression option the logical size isn't automatically generated. Currently the logical size is increased 4 times the physical volumes only for the default values.


Version-Release number of selected component (if applicable):
cockpit-ovirt-dashboard-0.11.11-0.1.el7ev.noarch
kmod-kvdo-6.1.0.146-13.el7.x86_64
vdo-6.1.0.146-16.x86_64
gdeploy-2.0.2-22.el7rhgs.noarch

How reproducible:
Everytime

Steps to Reproduce:
1. Login to the cockpit dashboard
2. Hosted engine deployment with gluster
3. In the bricks tab check the Enable Dedupe & Compression and look for the Logical size

Actual results:
The logical size is generated only for the default value set

Expected results:
The logical size should be generated automatically for any physical size given

Additional info:
Comment 2 SATHEESARAN 2018-03-06 07:10:04 UTC 
The logical size of the VDO volume should 10x as per the response from Dennis Keefe, currently the model chosen provides 4x

Here is the snippet from Dennis Keefe's response
<snip_from_mail>
> 2. vdoLogicalSize = 10 x ( Disk physical size )
> In actual, the cockpit implementation does 4 x size of physical disk.
> I read from the RHEL 7.5 storage admin guide, about the recommendation of 10:1

 The cockpit implementation will allow much large size, though you have to manually change the settings.
10x is typical for VMs.  I agree with this setting.

Verified the bug in the below component version's successfully.

Component versions's:
gdeploy-2.0.2-23.el7rhgs.noarch
cockpit-ovirt-dashboard-0.11.20-1.el7ev.noarch

Steps:
1. Install VDO 
2. Start the gluster deployment via cockpit UI and check the compression and deduplication tab.
3. Could see the logical size 10 times the physical size.

Result:
