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
Chris
