[Qlustar-General] upgrading qlustar from 10.1.1 to 11.0
Dear all, First of all I'd like to wish all developers/maintainers and users a happy new year and all the best. I know I am quite late with this topic, but other things distracted me so-far: I'd like to finally upgrade our cluster to 11.0. According to the upgrade instructions (https://docs.qlustar.com/en-US/Qlustar_Cluster_OS/11.0/html-single/Release_N...) it is more or less an apt distupgrade; but since there are a lot of changes and I have very bad experience trying to upgrade merely ubuntu-versions (which usually breaks), I can't believe it is so simple? So I'd like to ask whether it is really as simple and what your experiences are? Any caveats, things to keep in mind? Can I do it while calculations are running or should I rather wait for all of them to finish (we have run-times of months, therefore this is a thing in my case). Any advice/comment is very welcome. Best regards, Tobias

I'm interested in this too! This upgrade is on my to-do list and I'm a bit hesitant. Thanks, Bryan

It should be, as long as you follow the guide precisely. I didn't have problems while upgrading many customer clusters (otherwise they would have been solved by now anyway ;) ). Obviously we only install the minimum needed set of packages for a given cluster, so if you have pulled in many non-Qlustar related packages from base Ubuntu, you might run into problems on that side. But these should be rather minor and only concern the corresponding package(s). T> So I'd like to ask whether it is really as simple and what your T> experiences are?

Hi Roland, thank you for the answer and encouraging words; than I'll announce a maintenance for this and try it. I hope, we don't have incompatible packages/setups. @Bryan: Sounds good to hear that I am not the only one who still didn't upgrade; I'll keep you informed on my experiences. But as I mentioned, due to our long run times of cluster-jobs it will take some time. Best regards, Tobias On 07.01.20 16:16, Roland Fehrenbacher wrote:

Better to wait for calculations to finish. All nodes will need a reboot anyway. Ok, than I
