There are couple of things that bothers here: 1. 4K Native device support requires fixes at QEMU that will be part of CentOS 7.7.2 ( not yet available ) 2. 4K Native support with VDO volumes on Gluster is not yet validated thoroughly. Based on the above items, it would be better you have emulate512=on or delay your production setup ( if possible, till above both items are addressed ) to make use of 4K VDO volume. @Sahina Bose <sabose(a)redhat.com&gt; Do you have any other suggestions ? -- Satheesaran S (sas) > > On Fri, Sep 27, 2019 at 3:19 PM Sandro Bonazzola <sbonazzo(a)redhat.com&gt; > wrote: > >> >> >> Il giorno ven 27 set 2019 alle ore 05:21 Guillaume Pavese < >> guillaume.pavese(a)interactiv-group.com&gt; ha scritto: >> >>> I see that oVirt 4.3.6 finally has 4k domain support. >>> >>> -
