OOD desktop doesn't work on Rocky 8.7

Get Help

Hello,

I am testing ood desktop with Rocky 8.7 compute node. However, ood desktop keeps failing to start MATE on the node.
I followed MATE instructions from Rocky “MATE Desktop - Documentation”

Here is the error log.

I would appreciate it if you could help me how to resolve this issue.

Thank you

What version of OOD are you running?

These lines are jumping out at me. Is SELinux enabled on your system?

3

OOD 3.0 on Rocky 8.7

I saw the message but SELinux is disabled on both OOD and the compute node.

SELinux status:                 disabled
4

Could you post the submit/*.yml you are using for the desktop along with the form.yml? I’m thinking the SELinux is a dead end, and I want to see what is being passed back as this launches.

we don’t have submit folder

The submit.yml.erb would be the file if there’s no submit folder.

I tested it on 4 different environments. They submitted a job to the same host (CentOS 7.9).

The results are;

  1. OOD 1.6 on Centos 7.8 - Success
  2. OOD 2.0.32 on Centos 7.9 - Success
  3. OOD 3.0 on Centos 7.8 - Failed to connect to server
  4. OOD 3.0 on Rocky 8.7 - Failed to connect to server

Is there something changed in 3.0 to connect VNC?

9

No, there shouldn’t be a change, but I’m wondering if enforcement around an OOD convention is causing the issue.

If you look at the docs, anything under that root directory of the app will be treated as a form.yml and as such, OOD thinks it is an app. To ensure it is looking at those submit.yml and your_cluster.yml files correctly, you need to create a directory in the apps root such as submit/ and land the submit.yml.erb there while also adding the following to the app’s form.yml:

...
submit: "submit/my_submit.yml.erb"`
...

Which you can see here:
https://osc.github.io/ood-documentation/latest/enable-desktops/custom-job-submission.html

Then, for the cluster to work right using the docs here:
https://osc.github.io/ood-documentation/latest/enable-desktops/add-cluster.html

You will want a my_cluster.yml in the clusters.d/ dir you make, and then make sure the name of that file matches what you add to the form.yml:

...
cluster: "my_cluster"
...

Once you have that all setup, what happens at submit for the job?

It may be that previous versions did not enforce this file structure as strictly and why they worked, but there should be this separation of submits, forms, and cluster files to help make sense of what the various yml files do.

10

Thanks for the suggestions.
I created “/etc/ood/config/apps/uva_desktop/rivanna.yml”

---
title: "Desktop"
cluster: "rivanna"
submit: "submit/submit.yml.erb"

and moved “submit.yml.erb” into submit folder.
However, I got sbatch: error: Batch job submission failed: No partition specified or system default partition Slurm error.

I moved “submit.yml.erb” back to root directory and I was able to submit a job.

But still no VNC error.

11

You will want to leave that file in the submit folder or OOD will not recognize it as the submit. That is called out in the Danger banner in the docs:
https://osc.github.io/ood-documentation/latest/enable-desktops/custom-job-submission.html

Ensure you have the rivanna.yml cluster file in the /etc/ood/config/clusters.d/ directory.

Your app directory should have the following form at the end:

uva_desktop/rivanna.yml
uva_desktop/submit/submit.yml.erb

And the uva_desktop/rivannv.yml should have:

---
title: "Desktop"
cluster: "rivanna"
submit: "submit/submit.yml.erb"

And at that point, is this when you get the sbatch: error: Batch job submission failed: No partition specified or system default partition Slurm error. error?

12

I misunderstood and created submit folder in /var/www/ood/apps/sys/uva_desktop.

I moved the submit folder into /etc/ood/config/apps/uva_desktop/ and I have no issue submitting a job.

However, VNC still doesn’t work.

13

Ok, is the error that sbatch: error: Batch job submission failed: No partition specified or system default partition Slurm error message at this point or something else now?

14

no more Slurm error messages. Only VNC connection is the issue.

15

Could you post the output of the output.log and vnc.log from the session.

I have attached the log file.

I saw the Desktop session that was created by ood 3.0 in ood 2.0 and 1.6 since we are sharing the home directory. I was able to access the existing desktop session from ood 2.0 and ood 1.6 without any issues.

17

So, it looks like you need to remove some packages for this to work, and I apologize because this isn’t documented anywhere and I can’t find it in our own configs so you could never have known this (and neither did I tbh).

You need to remove:

  • system-config-printer
  • mate-power-manager

Those will cause issues when launching is what I am being told. What happens if you remove those and try to connect again?

18

Sorry for the late response. I was busy with other projects.

I removed two packages but still can’t connect VNC. Here is the output log.
