[Qlustar-General] 2nd stage configuration failed at the first step.

Hi, I'm having trouble getting pass the 1 boot process, which is to run /usr/sbin/qlustar-initial-config. After entering a name for the cluster, I always get the error HTTP access to the Qlustar repository is not possible Please check your curent network settings (received from DHCP): enp9s0: ..... Kernel IP routing table . . . Once you have made the required modifications, restart /usr/sbin/qlustar-initial-config! I can access the network (sshing to another machine), but cannot ping. It seems the DNS cannot be resolved (ping www.google.com results in the error "Temporary failure in name resolution.") Any hint on what I did wrong?

[Qlustar-General] upgrading qlustar from 10.1.1 to 11.0
by Tobias Moehle 08 Jan '20

08 Jan '20

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_…) 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

[Qlustar-General] HDD requirements
by mohd.farid.ismail＠yandex.com 07 Jan '20

Hi, I was looking at the hardware requirement, and am wondering how strict is the hard disc 160GB or bigger in size requirement. What I mean is, lets say if I use a smaller than 160GB disc, will the installation stop itself, or will it install anyway but with problems later down the road? --farid
