+++ This bug was initially created as a clone of Bug #1547509 +++ 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: --- Additional comment from Red Hat Bugzilla Rules Engine on 2018-02-21 08:11:30 EST --- This bug is automatically being proposed for the current release of Red Hat Hyperconverged Infrastructure (RHHI) under active development, by setting the release flag 'rhhi‑2.0' to '?'. If this bug should be proposed for a different release, please manually change the proposed release flag.
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. </snip_from_mail>
