[Qlustar-General] Upgrading from 10.0, still possible?
by david.whipp＠helsinki.fi 28 May '21

28 May '21

Hi all, I have a slightly neglected cluster that is still running Qlustar 10.0 without issue. I have been asked lately to install some software and noticed that apt is failing to find a number of packages when trying to update/install. This has led me to conclude I probably should finally take the steps to update the cluster over the summer. However, as I am running Qlustar 10.0 still, I am failing to find documentation about how to do this upgrade. It seems the path would be 10.1 -> 11.0.x and then 11.0.x -> 12.0. But I'm still using 10.0... So, here are my questions: 1. Is it still possible to update Qlustar from 10.0 to 10.1? If so, where can I find documentation about this update? 2. If I am stuck with 10.0, what is the best path to eventually running 12.0? Back everything up and do a clean install? And sorry if this topic has come up elsewhere. I had a quick look through the archives and didn't see anything. Thanks! Dave

[Qlustar-General] Qluman Writes Incorrect Permissions to /etc/sssd.conf on Diskless Compute Nodes
by hereiam＠mit.edu 30 Apr '21

30 Apr '21

Hi everyone, This is my first post, and so far I love Qlustar! Just what I've been looking for, you've done amazing work here. I noticed that my physical compute nodes, which are all diskless, fail when Qluman tries to write the Namespace Configurations. Upon trying lots of things, I found that the file /etc/sssd.conf is written with '644' permissions, causing the sssd.service to not start. However, when I manually change these with 'chmod 600 /etc/sssd.conf' and restart the service with 'service restart sssd' when SSH'ed into a compute node, it works perfectly. So my question is, how can I change the permissions of a config file which Qluman writes to all nodes? I think this is my last barrier to a properly provisioned cluster. Thanks, -Mike

[Qlustar-General] Error trying to install Qlustar
by juancarlos.armas＠russula.com 17 Feb '21

17 Feb '21

Hello, While trying to install Qlustar 12 on one node of the server appears the next error: "The installer has not found any unused disks, installation cannot continue". ISO is directly connected though KVM to the server, so install media shouldn't be the problem. Opening a shell and executing "mdadm --detail-platform" appears this error: "imsm capabilities not found for controller..." and doesent show the existing volume. I have a RAID0 configured with 2 SSDs on a Intel RSTe RAID controller. Model of the server is SYS-6028TP-HTFR. Other SOs can install flawless. Thank you for your help in advice.

[Qlustar-General] Physical front-end
by shoup.31＠osu.edu 08 Feb '21

08 Feb '21

Hi, I am new to this list. I have a small cluster (3 physical compute nodes, (8 cores/16 threads/64GB ram each) head node & VM-FE) with qlustar 12.0 installed. I am using it to run the Einstein Toolkit (numerical general relativity package). I would like to setup a physical front-end node for my system. My questions are: 1. Does the physical front-end node have to be net-bootable (via the head node)? 2. What qlustar software do I need on it? Is there an automated method for installing it? 3. Do I have to manually install slurm on it to submit jobs to the cluster from the physical front end node? 4. Do I need to register the physical front end node in qluman-qt? Thanks for any help you can provide. Tony...

Hi, In Qlustar 12 sssd.conf file contains filter_group attribute, when by manual it should be filter_groups. Nothing very bad happens, only warning in log file and this setting is ignored. Regards Rolandas
