I hope you could understand my problem.</div><div class=""><br class=""></div><div class="">Following the installation (with kolla ansiible) of an openstack (wallaby) on a physical server (under centos8), we were able to see all the possibilities offered in our teaching by Openstack. (i’m working in a french university).</div><div class=""><br class=""></div><div class="">For various reasons, we need to extend this manipulation. We will have 3 nodes (dell R740) and a Dell bay for storage.(dell compellent)</div><div class=""><br class=""></div><div class="">After having mounted a first test with 3 servers (T340), and put the storage (LVM) on node 3 (without the bay therefore) to test whether we had understood certain things correctly (in particular the parameter of the « multinode" file and that of « globals.xml"), we want to test with the Compellent bay.</div><div class=""><br class=""></div><div class="">My question is as follows: knowing that the 3 nodes are three identical servers, in the multinode file, how to configure [storage]… should one of the 3 servers be put, add the iscsid docker… or else put the IP of the bay . I admit that this aspect is problematic for me.</div><div class="">what about « enable_iscsii » and « enable_backends_lvm » parameters ?</div><div class=""><br class=""></div><div class="">In a configuration like mine, would you put a "controller" or 2 or 3?</div><div class="">Should we instead put an LVM on one of the servers and with iscsi make this LVM point the bay?</div><div class=""><br class=""></div><div class="">Maybe these are silly questions, I'm not sure. This use of the bay is new and I don't know how best to do it. Between cinder, lvm, iscsi, the bay, the multinode file and the options of globals.xml, it is still not easy at first</div><div class=""><br class="webkit-block-placeholder"></div><div class=""><br class="webkit-block-placeholder"></div><div class="">
