Description of problem: ------------------------ Till RHHI-V 1.6, thinpool on VDO devices are disabled, because of discard problems[1] with thinpool and VDO combination. This issue will be resolved with the update VDO systemd unit file, that enables the proper value of max_discard_sectors for VDO. This fix will be part of gluster-ansible bug[2] and once that is fixed, RHHI-V cockpit deployment should enable thinpool on top of VDO devices.

gluster-ansible-roles should provide VDO systemd unit file that should help in enabling VDO + thinpool
(In reply to SATHEESARAN from comment #1) > gluster-ansible-roles should provide VDO systemd unit file that should help > in enabling VDO + thinpool Because of this reason, it would be preferable to have this fix targeted for ovirt-4.3.6
Tested the bug with cockpit-ovirt-dashboard-0.13.6-1.el7ev.noarch. Tested the below: ================ * Check the enable dedupe and compression button,the thinpool is enabled. * After successful gluster deployment, could see thinpool is enabled with VDO devices Based on above results moving the bug as verified
