[Qlustar-General] HP Proliant DL360 G5 issues
by bscook999＠gmail.com 21 Mar '19

21 Mar '19

Hello. I'm having a lot of trouble getting the Qlustar 10.0 installer to recognize the the hard drives. During the installation process an error message comes up that there are no available hard drives and the FAI stops. HP Proliant DL360 G5 Smart Array P400i is working. I did a standard Ubuntu 18.04.2 Server LTS installation and the hard drives were recognized just fine. I'm not sure how to get the Qlustar to recognize it. Is it possible to install Qlustar from within ubuntu? I would prefer the automated installation process if possible to avoid errors, but if I can't get it to work. Please advise, thanks.

[Qlustar-General] Nodes won't boot
by Ansgar Esztermann-Kirchner 15 Mar '19

15 Mar '19

Hello List, recently, I've moved /apps to its own device. This invalidates NFS handles on the nodes, of course, so I started to reboot them. To my surprise, they don't come up again. The nodes complain about a time-out, "Failed to request QluMan node config in time", and ask me to check qlumand and qluman-route on the head. These two processes are indeed running. I've checked the logs, but couldn't fine anything helpful (to me) in there. qlumand seems to see the node briefly: 2019-03-05 11:45:06,615 [29219] INFO server.admin - Identifying node from '00-25-90-d9-08-86' 2019-03-05 11:45:06,617 [29219] INFO server.admin - Registering Execd 'node31-35' 2019-03-05 11:45:39,645 [29219] INFO server.admin - Execd '00-25-90-d9-08-86' disconnected I've attached the router log. There's one thing that's conspicuous, but it doesn't seem to be correlated with the nodes booting: a stack trace when accessing the database. I'll be grateful for any pointers.

[Qlustar-General] NVidia driver
by Bryan Hill 13 Mar '19

13 Mar '19

Hello All! Is there a way to get a newer nvidia driver working with the current Qlustar 10.1.1? The nvidia module in the Qlustar repo is 390, and we just received some nodes with RTX2080 Ti cards, which require >= 410 I've tried installing inside of a chroot, but it doesn't want to work. Thanks, Bryan

[Qlustar-General] IPMI Power
by Ansgar Esztermann-Kirchner 01 Mar '19

01 Mar '19

Hello List, what is the preferred way to power control nodes? IPMI setup is done by qluman, but there does not seem to be a way to control nodes from the GUI. I've found ql-remote-control, but it complains about a missing config file, and I did not find an example file to explain its syntax. Thanks, A. -- Ansgar Esztermann Sysadmin http://www.mpibpc.mpg.de/grubmueller/esztermann

[Qlustar-General] Qlustar installation on HP Gen6 servers
by jorma.ojala＠iki.fi 15 Feb '19

15 Feb '19

Hi, Qlustar 10.1 installation failed on HP DL320 G6 server. The server has got 4 x 1TB disks, but the installer reported 'no unused disks'. I recall that the server has got the P410 RAID-controller on-board. I tried with different RAID configurations but with no luck. Maybe this is 'too old' hardware for Qlustar ? Cheers, Jorma

[Qlustar-General] Failed to run qluman-cli -bootstrap during second phase installation
by clavila＠gmail.com 25 Jan '19

25 Jan '19

Dear all, I am trying to install the latest version of Qlustar (10.1) in a server. During the first phase everything runs smoothly. During this stage I opted to run the front end on a VM. I have also setup manual network configurations for both cl-head and cl-fe. When I start the second phase after reboot by running qlustar-initial-config I get an error during qluman setup. To try to isolate the error, i ran the qlustar-initial-config -i -d (interactive and debug flags enabled). The output that I get is attached below. Any ideas on how to fix this? Cheers, Cesar run "qluman-cli --bootstrap" [n] Yes -- Starting Qluman bootstrap ... Base MAC for VMs: 02:00:99:99:99:00 -- Registering VM for frontend node ...

[Qlustar-General] Add edge platform without QluMan Qt?
by Hernán Morales Durand 18 Dec '18

18 Dec '18

Hi, Inadvertently during installation I chose CentOS 7 as my edge platform and installing the QluMan GUI proves to be difficult on CentOS 7 due to missing Qt dependencies. Now I am stuck trying to install an alternative platform: root@plato:~ # schroot -l chroot:centos7 root@plato:~ # chroot-centos7 (centos7) root@plato:~ # yum update yum install qt-10 qt5-qtbase-devel mesa-libGL-devel mesa-libGLU-devel yum install qluman-qt Loaded plugins: keys, post-transaction-actions, protectbase 0 packages excluded due to repository protections Resolving Dependencies --> Running transaction check ---> Package qluman-qt.noarch 0:10.1.0.37-1.ql.el7 will be installed --> Processing Dependency: qt-10 = 10.1.0.37-1.ql.el7 for package: qluman-qt-10.1.0.37-1.ql.el7.noarch --> Finished Dependency Resolution Error: Package: qluman-qt-10.1.0.37-1.ql.el7.noarch (qlustar-10.1) Requires: qt-10 = 10.1.0.37-1.ql.el7 You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest I couldn't find how to install additional edge platform for my chroot environment **without** requiring QluMan, in the documentation : https://www.qlustar.com/book/docs/install-guide : "Note that you can always add support for a previously unselected edge platform later on by creating corresponding chroots and Qlustar images using QluMan." Is there an alternative way to add a platofrm without requiring the QluMan GUI? Is better to re-run the initial config again? /usr/sbin/qlustar-initial-config Best regards, Hernán

Hecho Creando árbol de dependencias Leyendo la información de estado... Hecho No se pudieron instalar algunos paquetes. Esto puede significar que usted pidió una situación imposible o, si está usando la distribución inestable, que algunos paquetes necesarios aún no se han creado o se han sacado de «Incoming». La siguiente información puede ayudar a resolver la situación: Los siguientes paquetes tienen dependencias incumplidas: qluman-qt : Depende: qluman-qt-3 pero no va a instalarse E: No se pudieron corregir los problemas, usted ha retenido paquetes rotos. It seems qlustar repository cannot be authenticated. Are there any additional steps to configure? Should I self-sign the qlustar repository? Cheers, Hernán
