[Qlustar-General] limit network access
by ignas.bunikis＠scilifelab.uu.se 05 Sep '18

05 Sep '18

Hej, I would like to limit access to the cluster via hosts.allow and hosts.deny. What is the best way to do it? I could create a script in /etc/qlustar/common/rc.boot/ that looks like this: #!/bin/bash echo 'sshd: ALL' >> /etc/hosts.deny echo 'sshd: localhost' >> /etc/hosts.allow echo 'sshd: xxx.xxx.xxx.xxx' >> /etc/hosts.allow Is that ok? Cheers, Iggy

[Qlustar-General] QluMan & Hardware Property Sets
by Ansgar Esztermann-Kirchner 30 Aug '18

30 Aug '18

Hello List, here's a question that cropped up during my search for HW Threads (see other message), but is actually unrelated: how do I edit HW property sets? If I use the pop-up menu to, say, change the number of cores from 10 to 20, the change reverts upon closing the property sets window. The context menu of the property has "Delete Property", but that has no effect; the context menu of the property set has "Edit Property Set", but that pertains only to the set's name and description, not the contained properties. Any ideas? Thanks a lot, A. -- Ansgar Esztermann Sysadmin http://www.mpibpc.mpg.de/grubmueller/esztermann

[Qlustar-General] HW Threads/Hyperthreading
by Ansgar Esztermann-Kirchner 24 Aug '18

24 Aug '18

Hello List, does Qlustar handle hardware threads? SLURM has the triple sockets/cores/threads, so I'd expect to be able to configure this somewhere. However, I couldn't find anything in the docs (or in QluMan). A. -- Ansgar Esztermann Sysadmin http://www.mpibpc.mpg.de/grubmueller/esztermann

Reinstalling Qluman interface on my VM Virtualbox workstation. All worked fine then I needed to reload Virtualbox. Did a clean install on Ubuntu 16.04 and I received the following error message will trying to access the public key. root@workstation:~# dpkg -l software-properties-common > /dev/null 2>&1 || apt install software-properties-common root@workstation:~# gpg --no-default-keyring --primary-keyring /etc/apt/trusted.gpg --recv-keys E6BA110F3C0BC307 gpg: no keyserver known (use option --keyserver) gpg: keyserver receive failed: bad URI root@workstation:~# gpg --no-default-keyring --primary-keyring /etc/apt/trusted.gpg --recv-keys E6BA110F3C0BC307 gpg: no keyserver known (use option --keyserver) gpg: keyserver receive failed: bad URI

[Qlustar-General] Qluman questions
by Ansgar Esztermann-Kirchner 29 May '18

29 May '18

Hello List, a couple of question regarding Qluman: -As far as I understand the docs, the hierarchy for nodes is supposed to be host < enclosure < rack. Putting a node inside an enclosure can be done easily via the node's enclosure pop-up, but I have been unable to put the enclosure inside the rack. The only method I did find (drag and drop inside the tree view) lead to an error: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/qluman-10/client/qt/TreeWidget.py", line 980, in dropEvent updates[slot.id] = {"child_enclosure_id": w.id} AttributeError: 'int' object has no attribute 'id' -How do I define rack types? We have 42U racks without any special slots, and 47U racks with a couple of special slots, and neither is present in Qluman by default. -How do I diagnose hardware mismatch problems? In the right hand pane of the Enclosure View, my test node shows a red wrench with tool tip "Hardware config doesn't match host". The wrench is shown on a clickable button, but when I click it, nothing happens. I couldn't find anything in the menus, either.

[Qlustar-General] When/How is slurm.conf generated
by Ansgar Esztermann-Kirchner 28 May '18

28 May '18

Hello List, next question: how is slurm.conf generated? On my fresh installation, slurmctld won't start, and there are no NodeName entries in slurm.conf except for "DEFAULT". I've added a dummy node via qluman in order to test general slurm functionality, but it doesn't appear in slurm.conf. Am I missing something? Do I need to boot the node in order for it to appear in the config? Thanks, A. -- Ansgar Esztermann Sysadmin http://www.mpibpc.mpg.de/grubmueller/esztermann

[Qlustar-General] Unable to generate one-time token

[Qlustar-General] PXE boot
by Bob Johnson 02 May '18

02 May '18

The nodes will not PXE boot. I see the standard install loads the Realtek r8169 driver. Based on past experience, my hardware requires the r8168 driver. Can the NIC driver be changed in qlustar? Do I execute the following commands at the root@cl-head~# prompt. Or from a different location? apt-get install r8168 -dkms rmmod r8169 lspci -s 3:00.0 -vv (verifies the r8168 driver is loaded) reboot thanks

Reviewing my notes from a few years ago, it appears that I am having some of the same issues with loading Slurm and creating a chroot file during the FAI install Do I need to preload anything before the Qlustar install? Thanks
