[ovirt-users] Status of Snaphots and LVCache for VDO volume in oVirt 4.3

Hi, Currently choosing VDO at volume setup forces creation of a thick LV due to a RHEL bug, cf : https://bugzilla.redhat.com/show_bug.cgi?id=1634551 https://bugzilla.redhat.com/show_bug.cgi?id=1600156 The latter was closed while pointing to the following workaround : https://access.redhat.com/solutions/3562021 It is also said there that full fix will be available in RHEL-8 Thin LV are necessary to enable volume snapshots and LVCache, and are currently not possible on VDO volumes Does the above comments in BZs mean that it will still not be possible to configure Thin LV for VDO volumes with ovirt-4.3.x/Centos-7.X either? We have been postponing rolling out oVirt-4.2 in production because of these two major cons. Please advise if you think RHEL-8 will be necessary in order to have VDO volumes on par with normal volumes (snapshots and LVCache). In that case we will deploy production asap without VDO. Should we instead force the creation of VDO volmume on ThinLV by tweaking the gdeploy configuration and applying the mentionned workaround?
