Happy to hear 1.5 is out.  What is the recommended upgrade procedure?  Does the cluster have to be taken out of service while upgraded? Do I upgrade monitors first? Can I run for an extended time with nodes from different versions?

 

Thanks in advance.

You use the same installer to perform the upgrade, it will detect there is a prior version and will ask if you wish to upgrade to the new version.

During the install, the node will obviously be down for the install time which is about 5 min, the cluster will keep functioning as it can tolerate a node failure. Upgrade nodes one at a time: upgrade a second node only after the first is restarted and the cluster is back to healthy.

You should start with the management nodes first. The cluster can operate with a mix of new and old nodes, but it is always best to complete the upgrade process in one shot and not keep the mixed state.
