Difficulties installing Qlustar 12 on HP server
by david.whipp＠helsinki.fi 03 Aug '21

03 Aug '21

Hi, I have an HP Proliant DL380p (gen8) server that has been used as our head node for a Qlustar 10 cluster for several years now. We've recently decided to upgrade to Qlustar 12 (via a clean install) and I have been having issues with the installer not being able to find a disk for the installation. When I boot from USB the installer starts as expected, but once it loads I receive the message "No disks found - The installer ha not found any unused disks, installation cannot continue.". I've done some googling and found a few similar issues, mostly related to RAID, but no solution yet. The server does have a hardware RAID disk controller (HP P420i) and the target disk is a RAID 1 logical volume. The odd thing is that dropping into a shell and using lsblk shows the target RAID volume and another on the same controller as /dev/sda1 and /dev/sdb1. The RAID partitions also appear in the output of `cat /dev/partitions`, and it appears that the hpsa module has loaded properly from the output of `lsmod | grep hpsa`. We've today updated the BIOS and RAID controller firmware on the server and are still having no luck with proceeding with the install (same error every time). I am tempted to test things with the installer for Qlustar 11, but it no longer appears to be available online. Any suggestions? Thanks! Dave p.s. I won't be able to have physical access to the cluster again until July 20, but can try to answer any questions that come up here in the meantime.

My email is with juno.com. They don't use relays. Installation requires a relay, the png example uses the DNS address. That has not worked for me.

09 Jul '21

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] 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...

[Qlustar-General] Happy new year with Qlustar 12
by Roland Fehrenbacher 09 Jan '21

09 Jan '21

The Qlustar team wishes you all the best for the new year and is pleased to announce the immediate availability of Qlustar 12.0.0 for download [1]. It updates Qlustar's core platform to current Ubuntu 20.04 LTS. The CentOS [2] edge platforms remain based on 7.9 (with integrated OpenHPC [3] 1.3.9) and 8.3 (OpenHPC 2). The highlight of this release is the move to LDAP as the user and group name service, replacing the NIS setup used earlier. A fully configured LDAP instance is created at installation time. Net-boot nodes may directly authenticate users against this instance or use conveniently synced flat passwd/group files when scalability is critical. QluMan has a new optional component [4] to manage the Qlustar LDAP instance. It consists of a User and Group Management interface, as well as a powerful tool to import users/groups from passwd-like flat files. The second major new QluMan feature is the ability for easy and clean integration of external LDAP or Active Directory services with the new Nameservice Providers [5] and Nameservice Configs [6] dialogs. Finally, the QluMan GUI has been ported to the current QT 5 toolkit. This was a huge 'under the hood' effort that ensures the long-term maintainability of QluMan and also improves its stability. Highlights among the various major component updates include Kernel 5.4.x, Slurm 20.02.x, CUDA 11.0, ZFS 0.8.5 and BeeGFS 7.2. Please read the release notes [7] for more details.
