ProxLB is running - but crashes when it gets to Storage Stats

[computerfreek]

Hey! Great project - love the fact that this exists!

Quick information
-Three hosts
-ISCSI Storage + CEPH Storage
-Frontend Network and Backend Network
-ProxLB is living on a Ubuntu 24.04 VM within the Cluster - Installed via .deb file

Error I'm getting:

ProxLB: Info: [node-update-statistics]: Updated node resource assignments by all VMs.

Did I do something wrong? I have the storage_balancing enable: set to 0. Shouldn't it be skipping this portion? I'm guessing its having an issue reading one of the storage locations?

Thanks!

Hey @computerfreek,

thanks for reporting and this looks like a bug and it would be interesting to know, which storage provides those kind of metrics that result in „ZeroDivisionError: division by zero“. I will have a look into this tomorrow.

The storage metrics are obtained in general, but not performed when not enabled.

PS: You should remove the password from the screenshot.

Thanks,

@gyptazy - Thanks for your posts and updates. Sorry for being a pain in the arse!!!

Yea.. I just saw that. Derp! New to using Github ticket/post feature. Couldn't see the screen shot. Hopefully it updated. Good thing its only used here, and it has been changed, lol.

If it helps - this is storage under cluster. Let me know if you need any logs or anything. Or what you need.

[gyptazy]

I have already an assumption there that this is related to the iSCSI. Unfortunately I need to create such a setup tomorrow, but this should also definitely not fail when storage balancing is deactivated.

here it’s 10:30pm now, will have a look tomorrow into that. Sorry for the bad starting experience.

[computerfreek]

Don't say sorry! You have created something that is your baby and someone that has no idea what the hell he is doing... Is attempting to set-it-up. We all have different setups! You can't predict them all. I praise you on your ability to create something like this. I can't do it.

I hear you on the time its 4:30 PM here.

Don't answer this now!
The pve-proxmoxlb-service-ui addon - I have the repo on the hosts. But when I try to apt install pve-proxmoxlb-service-ui - it can't be found. Am I missing something stupid here too?

Thanks again! And feel no need to answer tonight. This is not URGENT!

Found out that you pulled it for now - got it!!!

Good morning @computerfreek,

I just pushed a fix for this (and also avoid obtaining the storage metrics in general even when not needed). This should be fixed with 1.0.4b (d53a6f6). Can you give it a try and let me know if this fixes your issue?

Thanks!

[computerfreek]

Hey Thanks for the reply.

Sorry it took me a while to get back to this. Long story short, family stuff got in the way.

I'm having some issues downloading the new deb file. It appears the links don't work? Am I missing something?
cr.gyptazy.ch/proxlb/proxlb:latest <-- that doesn't go anywhere. When I ping it, I don't even get an ip address.

I also tried to update it via apt update/upgrade. It lists the latest version is 1.0.3.

Hey @computerfreek,

unfortunately, I'm currently rebuilding my whole infrastructure and also moving to a more generic TLD (see also #81). Therefore, not all services are already back - I just rebuilt the 1.0.4 beta and placed it here: https://cdn.gyptazy.com/files/os/debian/proxlb/

Cheers,
gyptazy

Hey! That makes sense! Projects take time! Thank you for your efforts. I will give that a go!

[computerfreek]

Installed the new DEB file over the old one. Restarted the service and it moved vms!!!! Your fix/patch worked!

Hey @computerfreek,

cool, glad to hear and thanks for testing :)

Happy VM moving :)
