Hi guys, I think that there are a little bit of confusion around this topic.... Pierre-Luc Dion posted an official documentation ( http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.6/hypervisor/xenserver.html#upgrading-xenserver-versions) that differs in many steps from that published by Geoff Higginbottom of Shapeblue and mentioned by Yiping Zhang... that is the same I've followed for my failed upgrade.
In the Cloudstack document, the host do NOT GOES into Maintenance Mode and I've to run the following scripts: /opt/xensource/bin/cloud-clean-vlan.sh /opt/xensource/bin/cloud-prepare-upgrade.sh Since in the Cloudstack doc the host do not goes in MM, they says that I've to migrate all the VMs manually: "Live migrate all VMs on this host to other hosts. See the instructions for live migration in the Administrator’s Guide." Cloudstack doc says also that I've to copy the scripts from Pierre mentioned: /opt/xensource/sm/NFSSR.py /opt/xensource/bin/setupxenserver.sh /opt/xensource/bin/make_migratable.sh /opt/xensource/bin/cloud-clean-vlan.sh Point 6 and 7 are strange.... I've to upgrade the entire cluster and clear the host tag BEFORE connect again to Cloudstack: 6)Repeat these steps to upgrade every host in the cluster to the same version of XenServer. 7)Run the following command on one host in the XenServer cluster to clean up the host tag... Shapeblue says that I've to manage again the Cluster after the upgrade the Pool Master and I can upgrade the other hosts later... Another thing that is worring me is the script: /opt/xensource/bin/cloud-clean-vlan.sh So, what it does?? What means "clean-vlan"?? :o On Fri, Jan 8, 2016 at 10:52 PM, Yiping Zhang <[email protected]> wrote: > Since I can’t use attachment, I just include the doc in the message. > Hopefully, the indentations and formats will go through properly. > > Yiping > > ---------- > XenServer pool manual upgrade from 6.2 to 6.5 using ISO > Reference article for upgrading XenServer pool used for Cloudstack > > > http://www.shapeblue.com/how-to-upgrade-an-apache-cloudstack-citrix-xenserver-cluster > > > Manual upgrade to XenServer from 6.2 to 6.5 using ISO > > > On CloudStack Management server > > * Edit the file /etc/cloudstack/managment/environment.properties to > include the following line at the end: > * manage.xenserver.pool.master=false > * Restart cloudstack-management service > * service cloudstack-management restart > > Pre-upgrade steps > > * Disable XenServer pool HA from XenCenter or CLI > * Backup XenServer resource pool configurations > * Take screen shot for pool network settings in XenCenter > * Take notes of Storage Repo mount points and NFS volumes. > > Inside CloudStack Web UI > > * Put pool master host into Maintenance (CLOUDSTACK ONLY!).
