<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">1 of our older clusters in use, consists of 2 nodes contain Fedora 20, with the virt-preview repository enabled.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">The Engine itself is installed on a dedicated server (CentOS 6) and is still on version 3.5.1.1-1.el6.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">During some maintenance a couple of days ago on the Fedora 20 nodes, also the installed vdsm package was updated by the engineer working on the nodes.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">We went from version ‘vdsm-4.16.10-8.gitc937927.fc20’ to ‘vdsm-4.16.26-0.fc20’.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">This morning I wanted to remove some old snapshots on running vm’s, only to find out that the delete button is once again greyed out.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I also created a new snapshot on a running vm to test if it would only happen on snapshots that were already there before the update, but the delete button would still remain greyed out.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Only turning off the vm allows me to use the delete button.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">When looking at the nodes within the cluster, they both still have Live Snapshot Support on Active.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Before the vdsm update, the live merge functionality worked perfectly.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Anybody experienced something similar?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Could It be because the Engine is still running on 3.5.1?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">We are also running 2 clusters with F21 nodes that have the same vdsm version nummer installed and they don’t have an issue at all; connected to the same engine.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Kind Regards,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Roel<o:p></o:p></span></p>
