Why are scripts attempting to run PBS without permission?? "proxmox-backup-client failed:"

[brainsoft1]

[edit] I'm pretty sure this is just me doing weird things and somewhere in the process the datasets are being polled, while pbs is offline or crashing out. If it's not actually part of the script process I'll just close this post with my thanks for your time!

PVE9.1.1,
Attempted scripts: Graylog, Grafana

I never used to see this but I get this for every install attempt now. Why is the community script attempting to touch my PBS? I never asked it to do that, and I was never asked in the advanced settings if I wanted it to.

I've tried troubleshooting a bit with AI but it's just running around in circles, accusing me of installing from the gui or running the scripts inside the lxc.. The only thing I can see so far is that it comes from the cleanup_lxc function, but I can't find where those are coming from. Google is about as useful as ever these days.

The PBS function is failing because I have PBS running in an LXC with a bindmount to a local zfs vault (vault exported to the other nodes via nfs/autofs). I have custom UID/GID mapping for the bindmount on both sides and custom ACLS set. PBS automatic backup works flawlessly. I will not map UID 100000 on the host beause it is common to every unprivileged LXC, hence the custom service users.

The only issue is the scripts are trying to do something I never asked for, never gave permission for, and isn't compatible with my installation as it currently sit. I'm sure this is because I'm not following a common pattern, but the script shouldn't be doing something that isn't identified. I assume it is ignore if there is no PBS, and it "just works" the rest of the time, but I just don't want it to try.

The only thing AI came up with is to export SKIP_PBS_BACKUP=true in /root/.bashrc, but that was ignored. I'm fine if something like that is the solution, but there is definately something I am missing here.

Shouldn't this be a question in the advanced setup? I don't want backups happening every time i install an lxc to test something out.

Install or Update? And do you run the script just with the bash line or do you use the PVEScripts local?
@MickLesk i cant recall we touch PBS stuff anywhere, or did you add anything in that regard?

This actually looks like it may be a PVE issue, where PVE is attempting to run a backup on LXC creation, NOT from the scripts at all. I've never used pbs-backup-client before (yet), so this is one is new to me.

This is running as root on the host console in bash.

Proxmox VE has a schedule in the data center settings under Backup. When a new container is created and the backup schedule is running, PVE automatically attempts to perform a backup.

The proxmox-backup-client is called by PVE itself, not by our scripts. We have no response to this feature, as not everyone uses it. Therefore, there is nothing like this in any line of code.

You can check:
pvesh get /cluster/backup
pvesm status | grep pbs

This is a PVE/PBS/Unpriviledged LXC issue, not a script issue.

Thank-you everyone! IW as going crazy but not paying attention.

Happens to me all the time. ADD instruction reading is a feature, not a bug. Unfortunately. 😂
