How can we see the data store location fully?
I used to just put the name, but there's an error adding that method now. I think they want /mnt
Thank you.
Looks like I figured out the solution. I just needed to add the storage name, but I also had to remove the previous fingerprint.
Thank you.

Hi community,

it seems that as of 18th May my free PBS plan has stopped working. vzdump reports the error "backup failed: could not activate storage 'tuxis': tuxis: Cannot find datastore ...". When logging into PBS, I am unable to find my datastore. Is there any activity ongoing regarding the upgrade to PBS 2.2?

Thanks and kind regards,
Jan

I am seeing slow backup speed towards tuxis currently. Dumping onto a local disk yields a few hundred mb per second but running the proxmox server benchmark against tuxis yields:
Code:

The line speed (which I am able to reach) of my internet connection is 100mbit. No idea why it only manages to utilize half of it. Uploading a backup from Proxmox currently looks like this:

Somewhere on the way to tuxis I seem to be loosing a lot of bandwidth :/

was it better before? because you will lose some of your theoretical bandwidth to overhead, especially on slower and/or higher latency links.. the (TLS part of the) benchmark does basically nothing except upload in-memory chunks to the server where they get thrown away, so if there isn't some hickup going on over at Tuxis that's just the HTTP2 over TLS performance you are able to reach over that link (which will likely be slower than something like iperf)..

Yeah it was better, I was close to 100 MBit:
Screenshot 2022-06-02 at 10-01-05 pbs003 - Proxmox Backup Server.png

granted it somewhat fluctuates, but looking at the yearly maximum transfer rates since we started using tuxis (not that long ago):
Screenshot 2022-06-02 at 10-04-45 pbs003 - Proxmox Backup Server.png
I understand that due to the delta uploads etc there might not even be enough data to saturate the link. But I am currently uploading 300 GB which cannot be deduplicated. So at some point something somewhere got worse. Given that the TLS speeds are "just " 5 MB/s I'll try that from another server in the cloud to rule out other local problems.

Cheers,
Florian

EDIT: Seems to be something between my ISP and Tuxis, gotta double check, but this is what I get from the cloud:

Uploaded 352 chunks in 5 seconds.

Hi apollo13,

please create a ticket on https://support.tuxis.nl and i will look into it. My guess is that you already did, if so you got a reply in your inbox about 5 minutes ago :).

Br,

So, short update after further debugging. After moving the testclient outside the perimeter (or at least one firewall) results didn't get better. What did help though was tunneling the traffic to tuxis through a VPN. Which leaves me with the following possibilities:
* The VPN also changes the traceroute through tuxis, so maybe something on the original route is slow
* The VPN also hides the fact that we are using TLS/HTTP, so maybe a content inspecting firewall tries something stupid here.
* MTU issues which are gone through the VPN?

Any ideas on how to debug this further?

My guess is still at one of these above.
So i took a look at your provider to see if we could establish a direct peering session but that is not the case.
We do not have a IX where we are both present. I did however tickle one of our routers in a way that might impact the path your traffic takes.

Well you tickled it well enough. I am now getting routed via nextlayer in vienna:

Code:
 1  _gateway (10.7.21.1)  0.470 ms  0.428 ms  0.424 ms
 2  *  * * * *
 3  tengig0020-1702.cr1.grazkom.at (85.237.12.1)  4.206 ms  4.476 ms  4.556 ms
 4  xe-0-0-5-r25.inx.vie.nextlayer.net (81.16.152.121)  10.065 ms  10.062 ms  10.085 ms
 5  ae5-0-r03.inx.vie.nextlayer.net (92.60.0.244)  9.506 ms  9.503 ms  9.548 ms
 6  ae1-0-r60.inx.vie.nextlayer.net (92.60.0.233)  3.901 ms  3.579 ms  3.568 ms
 7  ae10-0-r06.nikh.ams.nextlayer.net (92.60.3.31)  21.014 ms  21.207 ms  21.008 ms
 8  amsix.tuxis.net (80.249.209.2)  22.753 ms  22.757 ms  22.766 ms
 9  pbs003.tuxis.net (185.119.31.23)  22.856 ms * *

and speeds are back up to 12 MB/second (an improvement with a factor of 3 more or less). Is that change persistent (or can you keep it persistent) or will the router loose it again once it stops laughing? Is there anything I could do on my end to improve this (talk to my ISP?)

Either way, thank you very much for your help in debugging!

That's what we hoped :).

We are 'relying' on AMS-IX routeservers, as long as Tuxis and NextLayer are connected it works like it is now. But the internet is a wild place, so the route might change at a later moment.
Regarding your 2nd question, there usually isn't much that you can do as a end-customer. It is either your partner (us) or your ISP or a combination of both that needs to do something router based to change the path.

> Either way, thank you very much for your help in debugging!
Happy to help.

@tuxis Is the free 150GB offer still valid? :)

Placed an order yesterday evening but still no confirmation mail or something like that.
