I have a couple of completed CPDN tasks showing now, so it all looks good. That's that one done. Hooray!

I had to restart my computer after a kernel update earlier today, so I took the opportunity to see if BOINC Manager started from the Ubuntu launcher icon now. It doesn't work - again, like in Message 57094, the BOINC Manager icon flashes 6 times (ie. about 12 seconds), but that's all that happens, so I have to start it from a terminal using 
boincmgr
.

I'm just looking at the problem now.

I've just posted to a CPDN Message Board about it as well.

I just looked at an example of a work unit for which I had had a "Computation error", and it looks like all of its tasks have had errors on a variety of computers with different operating systems. I am computer 1326407 for that work unit.

It would be a shame for me to run out of free memory. I got several times what I (thought that I) needed, but maybe I should have gone straight to 128GB (the vendor's maximum) right from the start. Or maybe even 512GB.

Hopefully these errors are happening because of some quirk with the current batch of CPDN work units.

Update: A couple of tasks have appeared from yesterday (for CPDN errors). Hopefully, they're the same type of error that I used to see before I moved from SSD to HDD for work units.

Yes I just noticed another CPDN task "Computation error". I have had about 4 or 5 instances of "Computation error" with CPDN before. These tasks seem to be a week old, which is when the work units were happening on my SSD.

I noticed the "Computation error" last night mostly for POGS tasks, which is unusual. They have always been OK before.

I haven't installed Cuda so I have never had GUPGRID working 100%. I have only completed GPUGRID tasks that require only CPU.

Gotcha. Thanks.

I don't know what happened, because between Message 57095 (not working) and Message 57096 (seemingly working) I didn't change anything, but BOINC Manager (and BOINC) still appear to be working. Maybe the computer just needed that second restart.

Since Message 57096, it seems like there have been a higher proportion of "Computation error", and some tasks with a Remaining (estimate) of over 7 hours have been "Ready to report" within about 10 seconds or so of starting to run, but I'll leave BOINC Manager running for a couple of days and see what happens on boincstats (for example).

Thanks very much for your help - particularly Message 57075.

Despite those messages, I've added some other projects, tasks have downloaded, and the tasks have now started "Running".

Happily, I have 32 tasks running again, whereas before this move I was down to 23 concurrent tasks.

I still can't be 100% sure that it's working until these work units are completed and uploaded, of course, but it's looking pretty good.

The /mnt/InternalHDD/boinc-client folder has all the correct subfolders etc:

OK I left my computer for an hour or so, and restarted it a little while ago. I wanted to copy and search for the error text when starting boincmgr (I didn't try starting BOINC Manager from the Launcher icon). This time, the application started OK, and I have been able to add a project. I don't know if it's working yet, because of Status "Communication deferred 00:59:59", so I'll add some more projects and see if it tries to start calculating.

I had a quick brainwave, so I started boincmgr from a terminal. It starts, but in the terminal I get the message

"execvp(/home/el_gallo_azul/boinc, --redirectio, --launched_by_manager) failed with error 2!"

Also, the BOINC Manager application shortly (within a minute or less) gives the message

"The BOINC client has exited unexpectedly 3 times within the last 2 minutes. Would you like to restart it again?"

I'm getting closer.

sudo mkdir /mnt/InternalHDD

sudo chmod o+rx /mnt

sudo chmod o+rwx /mnt/InternalHDD/

- In /etc/fstab file, change

"UUID=4f721fc0-8072-453f-b48f-ca686bd89549 /media/el_gallo_azul/Storage ext4 defaults 0 2"

to

"UUID=4f721fc0-8072-453f-b48f-ca686bd89549 /mnt/InternalHDD ext4 defaults 0 2"

-Reboot
- Check that /media/el_gallo_azul/ and /mnt/ look OK

- Uh oh
sudo /etc/init.d/boinc-client stop
gives "* BOINC data directory '/media/el_gallo_azul/Storage/boinc-client' does not exist."

sudo chown -R boinc:boinc /mnt/InternalHDD/boinc-client

sudo chmod u=rwx,g=rwx,o= /mnt/InternalHDD/boinc-client/

sudo rm /var/lib/boinc-client
(to delete previous link from /var/lib/boinc-client to /media/el_gallo_azul/Storage/boinc-client) then

sudo ln -s /mnt/InternalHDD/boinc-client/ /var/lib/
(to create new symbolic link)
- Edit /etc/default/boinc-client file with BOINC_DIR="/mnt/InternalHDD/boinc-client"

- Reboot
- Try to start BOINC Manager. The BOINC Manager icon flashes 6 times (ie. about 12 seconds), but that's all that happens.

Happily, 
sudo /etc/init.d/boinc-client start
(or stop) or 
sudo service boinc-client start
(or stop) work OK (although I won't be able to add any projects until the Manager is running).

Dropbox was easy to fix, but VirtualBox will be a bit of fun.

Thanks Juha.

I was going to make a post to the thread yesterday (that I had moved /var/lib/boinc-client to the HDD, created the symbolic link, checked that permissions had been kept for the boinc-client directory, and updated /etc/default/boinc-client, but that BOINC still didn't work) but boinc.berkeley.edu seemed to be down most of the day.

I suspected that the next thing to tackle would be the permissions, and then luckily I saw your post before I changed anything. What you say about /media/el_gallo_azul/ makes sense.

I'll remount the HDD to /mnt/ (etc) later today. It looks quite promising.

Post:
This is the total disk space used by everything that's on that drive, including the operating system and it is the number that BOINC then follows for the "Use at most N% of total disk space."

Right yes that makes sense. I misunderstood when I originally read your message to mean that BOINC had used 63.7GB, when in fact you meant that is the total I have used for everything.

I have flagged this questionable behaviour with the developers. We're having a discussion about it on the BOINC Alpha email list. So perhaps that your problems, at least with the "0 means no restriction" gets a little change here in the future. We'll see.

I am back in the process of getting BOINC to use my HDD instead of my SSD for work units. So far, I've managed to get the HDD to mount at startup, which is a big step forward.

The next trick will be getting the permissions etc correct when I try it again.

Here is the final post of thread 8857. Unfortunately (but understandably) I am not able to respond directly to it.

I'm back on the case. My SSD had a sudden failure. I've replaced it, and then a couple of weeks later the number of concurrent tasks started to drop, so that means that I should just give BOINC loads of space on the HDD.

I've managed to get the HDD to mount at startup, which was preventing the move previously.

Now to get the BOINC data folder and its permissions, and those other configuration items, sorted out. Not today though.

OK thanks. What I meant by 'default' was that I have never changed the settings. I installed the application and some projects, and have never changed anything other than that which is why I wanted to find out why the number of concurrently-running tasks has been decreasing recently.

BOINC states you've used 63.7GB

That's mighty interesting. Where did you get that number from?

Yes I will indeed do that, but all this has prompted me yet again to get BOINC work units happening on my internal HDD instead of my SSD, which I strongly suspect (ie. I'm 95% sure) has not been possible because I have never been able to get the HDD to mount at startup.

In the meantime, I am receiving more of those messages (for more projects), but luckily I still have some tasks running, even though there are only 23 running instead of 32.

What do your Boinc Computing preferences say for Disk and memory usage?


Here's how I have my Computing preferences... > disk and memory usage set.

All of my settings are the default settings, and my understanding is that "Disk usage" > "Use at most" of 0.00 means whatever the application thinks is best. It has been 0.00 since a year ago, and I have done many tasks since then.

If that setting actually means "Use at most 0.00 Gigabytes disk space", then it is not consistent with the message "You have 24.70MB available...".

As an aside, in the long run I want to find a way to mount the internal HDD at startup, to reduce the number of write cycles to the SSD.

This quirky issue has happened before.

I am receiving notices on the BOINC Manager "Notices" tab for more than one project that
(Project name) needs YYY more disk space.You currently have (small number) available and it needs YYY.


I actually have much more available space on that disk.

Where is BOINC Manager getting these numbers from?

How can I stop this from happening?

It wouldn't matter except that I think it prevents some tasks from being downloaded and carried out.

I attach:

1. A screenshot of the "Disks" utility (gnome-disk-utility) showing that the disk has 154GB free;

2. A screenshot of the Nautilus "Properties" window showing that the disk has 143.3GB free;

3. A screenshot of the BOINC Manager "Notices" tab showing the mysterious notices stating that I have 0.00MB and 24.70MB available for two different projects, which isn't true.

I took all of these screenshots within a few minutes of each other.
