slurmctld for Qlustar 10.1.1
by Lorenz Dettmann 06 Jul '23

06 Jul '23

Dear Sir or Madam, I am writing this E-Mail to you, because I am searching for a specific .deb package for slurmctld, which should run on a Qlustar OS version 10.1.1. After executing 'apt install slurmctld', I get the following error message: Err:1 http://repo.qlustar.com/repo/ubuntu 10.1-xenial/main amd64 slurmctld amd64 17.11.9.2-ql.3+10-xenial 404 Not Found E: Failed to fetch http://repo.qlustar.com/repo/ubuntu/pool/main/s/slurm-llnl/slurmctld_17.11.… 404 Not Found E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? Indeed, this package for slurmctld with this specific version is not in this repository anymore. Is there any chance of getting it from somewhere else? Many thanks in advance.

End-of-Life for Qlustar 11
by no-reply-list＠qlustar.org 27 Jun '23

27 Jun '23

This is to inform you that with the latest security release, Qlustar 11 has reached its end-of-life and will receive no further updates of any kind. Please update your clusters to Qlustar 13 and be aware that you will have to move first to Qlustar 12 and then do the update to Qlustar 13. This is the only supported upgrade path. Good luck!

Qlustar Feature Update 06/23
by no-reply-list＠qlustar.org 15 Jun '23

15 Jun '23

A number of new Qlustar features were completed recently and published together with the latest security updates. Version 13.2.0 further improves QluMan with the addition of: - An informative HOST OVERVIEW TABLE [1]. It provides a tabular overview of all the hosts in a cluster split by networks. Tabs at the top allow to select the network one is interested in. In each tab, the IP ranges allocated in the chosen network are shown at the top and a list of hosts with their most important config parameters below. An on-the-fly string/regex filter can be applied to the lists restricting the view to the hosts matched. - New GUI options to fine-tune the LDAP PASSWORD POLICY [2]. This makes it easy to control user password quality and protection against brute-force attacks with appropriate settings. - The possibility to ASSIGN A LUSTRE LNET NAME [3] to the network adapters of nodes and generate a new config file to bring up LNet during boot of Lustre nodes. - The automatic creation of a new configuration file during boot that lists a node's QluMan Generic Properties and their values. This allows to use freely definable Generic Properties as a general key/value store in customization scripts on Qlustar nodes. AlmaLinux was updated to version 8.8 with this release.

Re: Password sync for ldap users.
by Beethoven Santos 03 Apr '23

03 Apr '23

This is also happening to me from time to time. But in my case, I added users through Qluman, as described in the docs. These are the last lines of the /var/log/auth.log file on the FE node, right after the login attempt. ... > sshd[9118]: pam_unix(sshd:auth): authentication failure; logname= uid=0 > euid=0 tty=ssh ruser= rhost=10.0.2.159 user=********* > sshd[9118]: pam_sss(sshd:auth): authentication failure; logname= uid=0 > euid=0 tty=ssh ruser= rhost=10.0.2.159 user=********* > sshd[9118]: pam_sss(sshd:auth): received for user *********: 7 > (Authentication failure) > sshd[9118]: Failed password for ********* from 10.0.2.159 port 40398 ssh2 I've omitted the username and the timestamps and hostname columns from the lines above. Does anyone have any clue what might be going on? Do I need to show anything else? --- Qlustar Version: *12* Head-Node Kernel Version: *5.13.19-051319-generic* QluMan Server Version: *12.0.7.5* Image (FE) Kernel Version: *5.4.209-ql-generic-12.0-19* Image (FE) Version: *Qlustar 12.0.1.0-b548f1441*

Qlustar Feature Update 03/23
by Qlustar List 29 Mar '23

29 Mar '23

A number of new Qlustar features were completed recently and published together with the latest security updates. QluMan 13.1.0 highly improves on its Host Filter capabilities: - NEW FILTERS [1] for Property/Config sets, Property/Config types and Property/Config values have been added. These filters make it much easier to select correct groups of hosts for re-configurations or command execution especially on large in-homogeneous clusters. - COMMAND EXECUTION OR HOST SELECTION [2] using filters temporarily defined on-the-fly is now possible directly from the Host Filter dialog. This helps a lot in quickly checking on a group of nodes based on any configuration criteria. The Qlustar documentation has been expanded: - An HPC ADMIN MANUAL [3] has been added. It explains the recently introduced Qlustar HPC Core Stack and gives a detailed introduction to package management using SPACK [4]. - A section about WORKING WITH SPACK [5] has been added to the HPC USER MANUAL [6].
