Hi , I am completely new with qlustar. I would need some help to start having the cluster running as I don't really understand the doc. I did install qlustar (4 times) with no problem , Since I did not find out how to run the virtual FE node (and the demo mode VM by the way ). The last install was without create a virtual FE node. Following the section "1.5.5. Spack Package Manager" , it assume that I installed the FE node which I did not . There' s no alternative. I tried in vain to switch from root to user softadm in the main terminal , the user softadm is not even in the /etc/passwd. Under root I try my luck with the spack command leading to : spack compiler find -bash: spack: command not found
How to do the spack section without creating the virtual FE node ?
Also I don't mind reinstalling qlustar with the FE VM node but I would appreciate how to run it.
Now here is my second question , how to run the demo VM ?
Here is my frustration sequences of event in case someone want to rewrite that part of the doc ;-)
demo-system -a start Starting VMs in a tmux session ... Created tmux session demo-system. => Attach with 'console-demo-vms'
So far so good so I ran console-demo-vms
Something happened and got a nice command line in the bottom of the terminal, but it looks like I am still on the front end , not in the demo VM , not only the prompt shows the front end hostname but htop command shows the whole ram of 32GB and CPU #, according to |/etc/qlustar/vm-configs/demo.conf|
|it should be : |
CN_MEM=1285 HA_MEM=1024
I am really confuse now, console-demo-vms did not show the demo VM ,
Any reason , what am I doing wrong here ?
Now from the head node under root :
0 root@jcluster ~ # dsh -a uptime beo-201: ssh: connect to host beo-201 port 22: No route to host beo-202: ssh: connect to host beo-202 port 22: No route to host beo-203: ssh: connect to host beo-203 port 22: No route to host beo-204: ssh: connect to host beo-204 port 22: No route to host
beo-201 are supposed to be the demo VMs,
I have many more questions but that's it for now but planing forward, I did managed to run QluMan_gui, I played over night (until 5am) trying to add a working user and add a node . etc ..
The doc for me for unusable, there's no tutorial online I could find (other than the first install which is very simple). I would be really appreciate if someone could describe the full procedure to add a node from catching the MAC address of the new node, building an image for that guy and include it in slurm. something to start with .
Thanks for your help .
I really would love to have qclusar working ASAP for my very urgent project research involving GPU
Thanks
