Message 67335 - Posted: 4 Jan 2023, 20:33:41 UTC - in response to Message 67332.  

In readiness for that technical meeting, it might be worth having a peek at https://github.com/BOINC/boinc/issues/139. That's a conversation initiated by CPDN volunteers some 16 years ago, as the original source https://boinc.berkeley.edu/trac/ticket/139 makes clear.

I doubt this would help honestly. Given there are only a thousand or so hosts with recent credit, and each has two upload slots by default, I can hardly imaging a few thousand or even tens of thousand partially uploaded trickle files will cause such a big trouble. That's negligible compared to total data the CPDN upload servers need to handle anyway. The recovery story has to be on the server side. I doubt most volunteers ever look at the forum, let alone ready to tweak local configs all the time even if the knobs are added.

I am more curious about what actually went wrong. Other than the mention of failure on storage array, it's unclear to me if the upload server run out of other resources and why so many hosts (mine included) still couldn't connect after VM migration.

The VM was moved before Christmas onto a block device of 2x12Tb. It either couldn't handle the transaction rate from the CPDN VMs or there is an issue with the underlying hardware - they are not sure which yet. So at some point in the near future they will probably transition to 4x6Tb but JASMIN are still investigating exactly what the issue(s) were. OS wise the ssh & httpd ports went down and no-one could log in (because there's no console access on this unmanaged cloud). That's all I understand at present.

Richard - I'll have a read. I may not get time to bring up all the points I'd like at the next meeting. It's only an hour usually and I think there will be lots to discuss about the JASMIN setup.

The upload server appears to be down again. I have informed CPDN.

Still going here. Took 5.5 hrs to upload all the zips for the first w/u. Could finish the lot by sometime tomorrow evening(late) if all keeps going.

Ok, I am getting the odd one or two through but most are failing with http transient errors. It did this before it finally died yesterday. Let's see what happens...
Edit: CPDN can still log into the machine so it appears to be up ok.

It seems OK here. I have uploaded all those 'trickle(.zip)" files, so my Boinc Client has downloaded a bunch of new tasks, and five of them are running as I type this.

(log times UTC)

Edit - that upload (and three others across two machines) is showing as having reached 100% before pausing. In my experience, that can mean that an onward transfer to backing storage has failed, rather than the upload server itself. But I didn't have enough logging active to confirm that.

Yesterday I uploaded all the zips, downloaded new WUs, uploads are stuck again and one of the finished WUs got a computation error due to missing upload. I'm not sure whether zips were lost due to the failure of my own machine a week ago or some upload problems.

Well I managed to get 2 w/u worth of zip files uploaded but it seems to have gone "pop" again. Nothing uploading. Good job those zip files are not 100+meg in size or we might never catch up.

Me too.
And they do not seem to be transient.

This is the first one in my Event Log, but it may have started a little earlier.

Just out of a meeting with CPDN. They understand what the problem is. The upload server will be restarted but with reduced max http connections to keep it stable as best as possible. At some point very soon (today/tomorrow) they will move the upload server to a new RAID disk array (which is what's causing the problem). They may decide to do the move before restarting depending on how quickly the JASMIN cloud provider can give them the temporary space they need to move the files whilst setting up the new server.

Well, I got a good load shifted yesterday. Provided they can get it started once more before the weekend - either tonight or reasonably early tomorrow - I should be able to survive.

One thing I've noticed - sometimes when the upload hiccups on an individual file, BOINC comes back and tries it another time. And sometimes it doesn't. So I've got about 20 tasks which I could report if I could just get those loose files tidied up. I'll see what I can do when the next window opens up.

Exactly why I would like user control of the order files are uploaded in.

When I was watching it upload my stuff yesterday, during the extended period of up-time, I noticed it picked tasks .zip files seemingly at random, but once it had picked one, it then picked others from the same task-id. E.g., oifs_43r3_ps0123. It usually picked all of them eventually. If it choked on one, it just went on to the next. Near the very end, it slowly picked up all the rest. I do not think it lost any. But this is my impression, not exhaustively writing down everything as it happened.

And some messages from BOINC:
I would recommend that you set http_debug, rather than http_xfer_debug. The output gives more detail about the reasons for errors.

And some messages from BOINC:
I would recommend that you set http_debug, rather than http_xfer_debug. The output gives more detail about the reasons for errors.

Well, it gives us those three useful lines. They tell you what you're trying to do, and why it failed. And it's fairly obvious that there's nothing we, as end users, can do about it: the project has to sort that out.

The guff about contacting the 'reference site' (google.com) might have been useful in the early days of BOINC, but I think we all have better and quicker ways of knowing if our internet connection is working these days. You can turn that off in configuration.

Latest update from CPDN as of 6/Jan 10am:
Upload server remains inaccessible to CPDN staff. The JASMIN cloud provider are creating a larger block store in order to deal with the Tb volumes to recover the data before recreating the upload server. Unfortunately, this will take some time. My personal guess is the server will not be back today.

Well, my new 2 TB SSD arrived by post this morning - that's probably a faster data transmission rate than the internet, just at the moment.

The question is - dare I attempt to install and mount it as BOINC's data drive, while I'm still hosting around 90 results waiting to upload and report? On balance, I think probably not.
