<p class="MsoNormal"><span lang="EN-US">Hello,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">We experience a RHEL 5.8 Cluster LVM problem these days on our four nodes cluster which are sharing 55 services (mainly oracle databases). We use to make all our LVM duties from the first node and we manage our services
(with clusvcadm –e RESSOURCE for example) from any node where it is lying at.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Can you explain us if there is a way to avoid these issues? We do not want to reboot our entire cluster and we are not able to do no pvdisplay or vgdisplay or others LVMs duties right now. Can we remove the /var/lock/subsys/clvmd
to use our LVM commands? Is a migration to the RHEL 6.8 a cure ? Please let us know what are the root cause of this problem and what would we apply to avoid this type of incident in the future.<o:p></o:p></span></p>
