Enabling pam_slurm and pam_slurm_adopt
by jan.kreps＠cvut.cz 04 Aug '22

04 Aug '22

Hello everyone, I want to enable pam_slurm and pam_slurm_adopt in my new cluster. In https://qlustar.com/about-qlustar/workload-management is written, that "QluMan provides an option to enable the Slurm PAM module." Unfortunately I can not find such an option in QluMan. In Qlustar documentation I did not find this information either. Can you provide information how to achieve this? Thanks Jan

Password sync for ldap users.
by saeed.s.jahromi＠gmail.com 02 Jul '22

02 Jul '22

Greetings, I have qluster 12 installed on a small HPC in our university. To create users remotely, I usually use the terminal and .ldif files to create users. I also use the following command to change users passwords from the terminal: ldappasswd -Z -D "cn=admin,dc=gavazang,dc=qlustar" -W -S "cn= saeed,ou=users,dc=gavazang,dc=qlustar" This works and the password is changed. However, the problem is that once in a while the user cant connect to the cluster and I have to reset the password again and again and this happens frequently. Should I do anything to sync the passwords after changing them? Or am I doing something wrong here? thanks in advance for your assistance

Qlustar Feature Update 06/22
by Qlustar List 28 Jun '22

28 Jun '22

A number of new Qlustar features were completed recently and published together with the latest security updates. QluMan 12.0.7.3 highly improves on its slurm management capabilities basically making the slurm component feature complete. It adds - Real SLURM QOS MANAGEMENT [1] in the GUI. QoS can now easily be added, edited, removed and assigned. The full list of QoS properties may be added/removed and manipulated including sanity checking the values entered. - SLURM ASSOCIATION AND LIMITS MANAGEMENT [2] has been added in the GUI unleashing the power of advanced slurm resource management to QluMan admins. Various visual filters have been created to achieve a comprehensive display of slurm associations. The full list of association settings may be added/removed and manipulated including sanity checking the values entered. * An 'LDAP GROUP <-> SLURM ACCOUNT' SYNC MECHANISM [3] has been designed to automate slurm user setup upon creation of the user in LDAP. Slurm accounts may be associated with LDAP groups such that depending on users primary group the corresponding slurm account will be assigned as their default. * Cron-based LDAP DB BACKUP was introduced to allow a disaster recovery in case the LDAP DB becomes corrupted. Other new features: - Update to AlmaLinux 8.6 [1] https://docs.qlustar.com/Qlustar/12.0/ClusterOS/qluman-guide/components/slu… [2] https://docs.qlustar.com/Qlustar/12.0/ClusterOS/qluman-guide/components/slu… [3] https://docs.qlustar.com/Qlustar/12.0/ClusterOS/qluman-guide/components/slu…

Using external LDAP server
by jan.kreps＠cvut.cz 13 Jun '22

13 Jun '22

Hello everyone, is there a way how to configure Qlustar to use external LDAP server instead of the one included in the installation? We run our own ldap server with passthrough authentication to Kerberos and want to use existing user accounts for Qlustar cluster as we did on our old cluster. Cheers, Jan

by ignas.bunikis＠scilifelab.uu.se 07 Apr '22

07 Apr '22

Hej, I was attempting to install Qlustar using latest installer (Qlustar Installer 12.0.1-0) on a few years old SuperMicro server. Installation seemed to go smooth, but after first reboot popped up boot error message that no bootable devices were found. During another installation attempt I noticed a couple of error message: * Failed to fetch file ..postfix... Hash sum mismatch * Failed to fetch file ..python-slurm... Hash sum mismatch * Failed to fetch file ..python3-slurm... Hash sum mismatch AND *GRUB/10-setup FAILED with exit code 127 After that installer says: Good news! No errors found in log files Do you have any ideas what could be an issue and what to do? Cheers, Iggy

users created with LDAP in QluMan can't connect to head node with ssh
by saeed.s.jahromi＠gmail.com 22 Feb '22

22 Feb '22

Greetings I have installed the qlustar on a small cluster with one head node and 15 compute nodes. I managed to add all nodes to the cluster and configure slurm on the cluster via QluMan. As the last step to make the cluster available to users, I started creating new groups and users with QluMan. after creating new users and syncing I tried to connect with users to the head node by ssh. However, all the users that I create can not connect to the head node because it says the user does not have premission. I also chose to create a virtual demo cluster during the installation and the demo user which is created during the installation also does not have permission to ssh login to the head node. I checked on the head node and all user's home directory is created in the /data/home/ directory but they can not connect to the cluster. I would be so thankful if you guide me on how should I resolve this issue or where in the qlustar config files should I look for the source of the problem. PS, this cluster was already using an older version of the qlustar from 6 years ago and we just updated it to the latest qlustar 12. Thanks in advance for your assistance. Saeed

tcsh segfault in Ubuntu 20.04 with external LDAP
by a.gabbana＠tue.nl 17 Feb '22

17 Feb '22

Dear Roland, we observe the following reproducible problem: - A fresh installation of qlustar 12 - A chroot with Ubuntu 20.04 - An external (fresh) ldap server (connection via shared conf files under /etc/qlustar/common/image-files) Calling tcsh returns segfault. The problem seems to be connected to libgssapi_krb5.so.2. The problem does not occur with a Ubuntu 18.04 chroot. Moreover, the problem does not occur with a fresh installation of Ubuntu 20.04 (without qlustar) connected to the same ldap Do you have any clue what could be triggering the problem / or can you suggest a possible workaround? best Alessandro

Qlustar Feature Update 01/22
by Qlustar List 10 Jan '22

10 Jan '22

A number of new Qlustar features were completed recently and published together with the latest security updates. QluMan 12.0.6.0 has the following new capabilities: - QLUMAN TIMERS [1] present a new Config class assignable to nodes. They allow for time-based execution of commands on nodes and are easily configured via the GUI. - ENHANCEMENTS OF THE SLURM GUI COMPONENT [2]: * Added on-the-fly job filtering and job grouping. * Significantly improved mechanism to transfer job data. The QluMan GUI is now able to smoothly handle thousands of jobs. - HARDWARE DETECTION INFO for nodes in the GUI Enclosure view [3] now transparently highlights misconfigurations, helping admins to track down faulty settings. - FILTERS IN USER/GROUP MANAGEMENT [4] have been added, making LDAP management a lot clearer and easier to follow. Other new features: - MELLANOX OFED [5] drivers and tools have been included for optimized support of clusters with newest Infiniband (IB) technology. Qlustar now automatically detects whether IB adapters supported by the current Mellanox OFED release are present and activates its drivers if that's the case. For all other IB hardware, the in-kernel drivers are used. - GPU DIRECT RDMA [6] support has been added for nodes running Nvidia GPUs together with IB adapters supported by Mellanox OFED. It provides a significant decrease in GPU-GPU communication latency and completely offloads the CPU, removing it from all GPU-GPU communications across the network. - The VIRTUALGL image module is now production ready. When used in a node image, Qlustar can provide 3D remote visualization on nodes with the required hardware.

Stack Smashing Detected During qlustar-image-reconfigure
by hereiam＠mit.edu 25 Nov '21

25 Nov '21

Hi everyone, I've got a new one for you all... I was updating my chroot image successfully using qlustar-image-reconfigure, and all was well. However, when I updated qlustar using apt-get upgrade as usual (I haven't done so since July), now I get this error whenever I try to reconfigure the chroot image: 0 root@geb /var/lib/qlustar/images/Standard-focal # qlustar-image-reconfigure Standard-focal Reconfiguring image Standard-focal focal/12.0 - creating squashfs for download using kernel flavour ql-generic-* *** stack smashing detected ***: terminated /usr/sbin/qlustar-image-create: line 661: 8766 Aborted DEBIAN_FRONTEND=noninteractive chroot "$IMAGE_DIR" pam-auth-update --package --force Building image Standard-focal focal/12.0 failed. Any idea what might have happened? I'm all ears, and can't seem to figure it out on my own. Thanks! -Mike

[Qlustar-General] Node Replacement Issue - Infinite DNSMasq Lease in /var/lib/misc/dnsmasq.leases
by hereiam＠mit.edu 25 Nov '21

25 Nov '21

Hi everyone, I've run into what may be an uncommon issue when replacing nodes in Qluman. Say I have a node all configured, then I completely remove that machine and replace it with a new one (may or may not be different specs). I have noticed that Qluman allows one to make the new node in the configs, but it never boots Qlustar. I also found the fix - the file /var/lib/misc/dnsmasq.leases doesn't appear to get updated *only when deleting a node.* Adding new nodes works perfectly, as does changing MAC addresses. However, I've had to go in and manually delete the corresponding entries from the file on the headnode, after which Qluman works perfectly adding a New Host with the old IP address. Can anyone else reproduce this issue, and if so, would an addition to the scripts to the tune of deleting the line matching the hostname or MAC address in /var/lib/misc/dnsmasq.leases be required for the next round of updates? It makes sense that leases should have infinite lifetime in a cluster (nodes should sit tight for years), though in this rare situation it requires a bit of extra manual tweaking. Thanks, -Mike

A few Qlustar 12.0 questions
by david.whipp＠helsinki.fi 20 Sep '21

Hi, First off, many thanks Roland for your earlier help with the Qlustar 12.0 installer. We've been up and running for a few months now and have almost everything working as desired. I'm writing because I have a few questions both about some issues we have not been able to resolve and some introduced in the latest security updates (QSA-0903211 and QSA-0903212). Latest issues first: 1. Since installing the latest security updates a few days ago I have noticed that Slurm has stopped working and the qluman-qt 'Components' option is grayed out (see https://imgur.com/a/W1Ejsvn). I'm not totally sure what the issue might be, but I noticed that the slurmdbd and slurmctld services are not running on the head node, and in fact are masked, which I understand will stop them from starting, right? You can see the output from 'service --status-all' and 'systemctl list-unit-files --state=masked' below. Any suggestions about how to re-enable Slurm? service --status-all: 0 root@geo-hpcc ~ # service --status-all [ - ] apache-htcacheclean [ + ] apache2 [ - ] console-setup.sh [ + ] cpufrequtils [ + ] cron [ + ] dbus [ + ] dnsmasq [ ? ] ganglia-monitor [ ? ] gmetad [ - ] grub-common [ - ] hwclock.sh [ - ] ipmievd [ - ] jobmonarch-jobmond [ - ] keyboard-setup.sh [ + ] kmod [ + ] loadcpufreq [ - ] lvm2 [ - ] lvm2-lvmpolld [ + ] munge [ + ] mysql [ + ] nagios4 [ - ] networking [ - ] nfs-common [ + ] nfs-kernel-server [ + ] ntp [ + ] postfix [ + ] procps [ + ] qluman-dhcpscanner [ + ] qluman-execd [ + ] qluman-router [ + ] qluman-server [ - ] qluman-slurmd [ + ] resolvconf [ - ] rng-tools [ + ] rpcbind [ - ] rsync [ + ] rsyslog [ + ] saslauthd [ + ] schroot [ - ] scsitools-pre.sh [ - ] scsitools.sh [ + ] slapd [ - ] slurmctld [ - ] slurmdbd [ + ] ssh [ + ] sssd [ + ] sysstat [ + ] udev [ - ] x11-common systemctl list-unit-files --state=masked: 0 root@geo-hpcc ~ # systemctl list-unit-files --state=masked UNIT FILE STATE VENDOR PRESET cryptdisks-early.service masked enabled cryptdisks.service masked enabled hwclock.service masked enabled jobmonarch-jobmond.service masked enabled lvm2.service masked enabled nfs-common.service masked enabled qluman-slurmd.service masked enabled rc.service masked enabled rcS.service masked enabled scsitools-pre.service masked enabled scsitools.service masked enabled slurmctld.service masked enabled slurmdbd.service masked enabled sudo.service masked enabled x11-common.service masked enabled 15 unit files listed. 2. In addition to the Slurm issue, I have also not been able to create new user accounts because the 'Components' option in qluman-qt is grayed out. I have previously migrated our old NIS user accounts to LDAP, but I am lackign experience with LDAP and unsure how to explore this issue. And finally, one older issue we have not resolved: 3. How do you change user passwords for LDAP users in Qlustar 12? I had been able to generate new passwords in qluman, but have not been able to figure out how what users should do to update their passwords. It seems perhaps there is a lifetime to the autogenerated passwords, so I have manually reset passwords when users needed them. Obviously, this is not something that is good in the long run. Do you have a suggestion? And sorry for the compilation of questions above. Hopefully the fixes are obvious to you and not too much trouble. Best, Dave

Qlustar 12 install fails on dell 3640
by maximilian.freudenberg＠uni-goettingen.de 10 Sep '21

10 Sep '21

Hi everybody! Yesterday I tried to install Qlustar 12.0.1-0 on a dell 3640 using a USB stick. Secure boot is off, legacy boot not available. I was able to start the install procedure, entered all details, read through the summary, hit enter, and BANG! big wall of running text. I took a photo and could decipher “stop_fail_installation task_error task_savelog die” repeated all over, which is almost poetic, but doesn't help much. Do you have any advice? How could I encircle the problem? It occurs no matter which distro or packages I select. Two things which are probably unrelated: 1) I had to reinsert the USB stick during the pre-install procedure, as there were problems during USB device discovery (as with every linux I have ever met). 2) I don't know if the mail relay I entered is valid. Kind regards Max
