I'm currently not getting any Rosetta work units. I see a message in my logs that states:

Tue 09 Feb 2016 07:49:02 PM CST | rosetta@home | Rosetta Mini needs 233.78MB more disk space.  You currently have 719.89 MB available and it needs 953.67 MB.


And disk available in the /var/lib directory (where AFAIK Rosetta and other BOINC projects store data files)

hbarta@yggdrasil /var/lib/boinc-client $ df -H .
Filesystem                                              Size  Used Avail Use% Mounted on
/dev/disk/by-uuid/6a4d9d0c-ff6f-4cbe-8aa2-e2b126e87b4e   37G   15G   20G  43% /
hbarta@yggdrasil /var/lib/boinc-client $ 


With 20GB available I do not see where BOINC is getting it's disk space indication.

This is on Linux Mint and Boinc identifies itself as
Sun 31 Jan 2016 09:30:42 PM CST |  | Starting BOINC client version 7.2.42 for x86_64-pc-linux-gnu


Is this a Rosetta or a BOINC problem?

Thanks!

BOINC Manager has some settings which allow you to limit the amount of disk it consumes. So your description that space is available, and the error you are seeing makes me tend to believe you will need to change your BOINC settings.

You can set these on your host machine in the preferences. Not certain how it looks in Linux, but on Windows it is the Disk and Memory tab. Looks like if you do not see other methods to set it, you could do so by modifying the global preferences file as described here. See that there are several disk_max and disk_min settings that all must work together.

Hi Mod.Sense,
Thanks for the reply and the pointer to the text config file. Here is the content of /etc/boinc-client/global_prefs_override.xml:

<global_preferences>
   <run_on_batteries>1</run_on_batteries>

   <ram_max_used_idle_pct>100.000000</ram_max_used_idle_pct>
   <max_bytes_sec_up>30003.200000</max_bytes_sec_up>

   <daily_xfer_limit_mb>0.000000</daily_xfer_limit_mb>
   <daily_xfer_period_days>0</daily_xfer_period_days>
</global_preferences>


The text settings match what I see in the GUI in Tools -> Computing preferences... -> disk and memory usage.

Is there something in my settings that causes this problem? I hadn't changed them before I noticed this (and they were probably at default values.) I think I have modified them since to see if that helped with this problem and it did not.

Thanks!

Hi

My guess would be that you have another project taking up some of the 1GB that BOINC is limited to in your settings:

<disk_max_used_gb>1.000000</disk_max_used_gb>

If that's the case, can you increase that to give Rosetta more room?

Yes, I agree. The line dcdc refers to appears to be the problem. I'd suggest 1GB plus 1GB per core. I believe the default here is zero, which means the amount of disk is only limited by the max %, and the min. remaining space settings.

Yes that was it. I increased that parameter to 5.0 and am getting work units again.

Many thanks for your help.
