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

No Bootable Device Found during post install boot
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

Hello, I am using the latest version of Qlustar 12.0 (FOCAL) I have a question about adding users. I use the qluman interface and I add an account via the menu component > ldap During the creation of the account, I have an error message which is the following: "Error 1 running add_user_hook /etc/qlustar/common/add-user-hook on beosrv-c: ('Unable to contact slurm controller (connect failure)', 1800) ('Unable to contact slurm controller (connect failure)', 1800) Traceback (most recent call last): File "/usr/lib/python3/dist-packages/qluman-12/qluman-slurm-cli.py", line 66, in main slurm_acct = SlurmAcct(cf_file, dry_run=args.dryrun, reset_all_qos=args.reset_all_qos) File "/usr/lib/python3/dist-packages/qluman-12/components/slurm/cli.py", line 87, in __init__ self.get_slurm_ctl_info() File "/usr/lib/python3/dist-packages/qluman-12/components/slurm/cli.py", line 112, in get_slurm_ctl_info c = pyslurm.config() File "pyslurm/pyslurm.pyx", line 376, in pyslurm.pyslurm.config.__cinit__ File "pyslurm/pyslurm.pyx", line 432, in pyslurm.pyslurm.config.__load ValueError: ('Unable to contact slurm controller (connect failure)', 1800) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/qluman-12/qluman-slurm-cli.py", line 96, in <module> main() File "/usr/lib/python3/dist-packages/qluman-12/qluman-slurm-cli.py", line 69, in main sys.exit(1) NameError: name 'sys' is not defined Traceback (most recent call last): File "/usr/lib/python3/dist-packages/qluman-12/qluman-slurm-cli.py", line 66, in main slurm_acct = SlurmAcct(cf_file, dry_run=args.dryrun, reset_all_qos=args.reset_all_qos) File "/usr/lib/python3/dist-packages/qluman-12/components/slurm/cli.py", line 87, in __init__ self.get_slurm_ctl_info() File "/usr/lib/python3/dist-packages/qluman-12/components/slurm/cli.py", line 112, in get_slurm_ctl_info c = pyslurm.config() File "pyslurm/pyslurm.pyx", line 376, in pyslurm.pyslurm.config.__cinit__ File "pyslurm/pyslurm.pyx", line 432, in pyslurm.pyslurm.config.__load ValueError: ('Unable to contact slurm controller (connect failure)', 1800) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/qluman-12/qluman-slurm-cli.py", line 96, in <module> main() File "/usr/lib/python3/dist-packages/qluman-12/qluman-slurm-cli.py", line 69, in main sys.exit(1) NameError: name 'sys' is not defined" I delete the account and I recreate the same account. Qluman gives me a password and I can connect as a user. Or am I making a mistake thank you

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
