Description SATHEESARAN 2019-03-28 12:27:01 UTC
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.
