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
