Dear Support Team, I would like to tell you that I am installing Qlustar 12.0 in my master node and also completed the installation. I am writing this mail to you because I am not able to connect my compute nodes to the master node. I have even created a certificate for the connection but am not able to proceed further. After putting the password for the certificate and clicking on the connect button a GUI is opened but nothing happens. I am watching the Screenshot kindly go through it once. Please do the needful for the mentioned above. -- Thanks & Regards *Kshitiz Pathak* 7710952632 Mumbai

[Qlustar-General] how to add GRES resources to qluster manually
by rolnas＠gmail.com 28 May '21

Hi, In my cluster I have two exotic IBM Power servers with NVIDIA cards. I succeded install Ubuntu 18.04 and make slurm working qith qlustar 11 server, but for NVIDIA cards to manage I cannot find any way to add manually those resources to global slurm config (gres.conf is managed by qlustar and no way to add something manually). Regards Rolandas

[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
