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

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
