I am suddenly experiencing a no disk space problem with BOINC on Ubuntu 16.04. I'm not too well acquainted with Linux yet so I'm having trouble figuring out why.

In BOINC preferences I am allowing 100 GB disk space usage and only 9 GB is being used according to the /var/lib/boinc-client folder properties.

Here are some outputs:

  • How are we supposed to read this? Please edit or repost. Cheers, Al – heynnema Aug 30 '16 at 20:14
  • Sorry about that, Al. I wasn't paying attention. It formated itself okay on the GPUGrid boards but I didn't get a reply yet. – SolarSurfer Aug 30 '16 at 21:28
  • You're welcome, @SolarSurfer! :-) Anyway, it seems that @edwinksl is a much better editor than me. :-) I should learn! – Cristiana Nicolae Aug 31 '16 at 6:20

Okay, I found out how to fix the problem, though I don't know if I fully understand why it occurred, or rather why I was unable to get accurate information to diagnose it.

It turned out that the climateprediction.net folder in my BOINC folder was full of 100 + GB of old and crashed work units. That was preventing downloads of any other project's tasks too. I didn't relish the prospect of hunting down the active work units in that bunch and saving them, so I just reset the project and now everything is working again.

I had originally opened Nautilus from Cairo-Dock, right-clicked on the BOINC folder and chosen properties. That informed me that there was 9 GB used and 100 + GB free space. However, when I thought to open Nautilus using 'gksudo nautilus' in a terminal I got different results and was able to pinpoint the problem. I don't understand why it should make any difference but it seemed that it did.

I should add, in my own defense, that I spent Sunday night in the ER of a local hospital and had only got one or two hours sleep - and I still haven't caught up yet.

Cheers!

  • Well, even if you don't have an explication yet, the important fact is that you have solved your problem. In this case then, I think that you should mark your own answer as the solution, so that your question could be classified as being solved. Thus, other people who encounter the same problem as yours will be able to find the answer more rapidly and easier. If I am correct, in order to do that, you'll have to wait for a day or two. (Meanwhile, other answers are supposed to come.) So, do come back! Regards! – Cristiana Nicolae Aug 31 '16 at 6:28
  • Will mark it after 18 hrs have elapsed @Cristiana, since apparently them's the rules :-) – SolarSurfer Sep 1 '16 at 1:14
  • Also, thank you @edwinksl, for the nice edit. I tried to thank you yesterday but the 'add comment' button wouldn't cooperate. – SolarSurfer Sep 1 '16 at 1:19
