I have the latest boinc server software running on Ubuntu 12.04

bin/db_dump -d 2 -dump_spec db_dump_spec.xml gives me

..html/stats and ..html/stats_tmp folder have chmod 02775. Where is the problem?

You are trying to run it in root of the project directory (or whatever it's called) and apparently it's expecting to be run in bin directory.

edit: Of course you can edit the directories in db_dump_spec.xml. edit2: But then again, when run as cron job, it's run in bin so maybe you don't want to edit the directories.

Should be ok with the root dir but perhaps a bug somewhere? With sudo command I got the same error.

Edit:
Got it, I have changed all the files from ../html to html/

Do notice that it very likely will not work as cron job/periodic task anymore. See config.xml how it's started.

Yes, thats correct, only needed for creating stats the first time but the cron job isnt working, tried bin/start --cron.

I have made a deeper look into the cronjob. All my modifications are correct but it still doesnt work.

bin/db_dump -d 2 -dump_spec db_dump_spec.xml -->update my stats

test.cronjob refers to test root

0,5,10,15,20,25,30,35,40,45,50,55 * * * * cd /home/boincadm/projects/test ; /home/boincadm/projects/test/bin/start --cron

db_dump_spec.xml is looking into html folder

<output_dir>html/stats_tmp</output_dir>
<archive_dir>html/stats_archive</archive_dir>
<final_output_dir>html/stats</final_output_dir>

from the config.xml
<task>
<cmd>db_dump -d 2 -dump_spec db_dump_spec.xml</cmd>
<period>5 minutes</period>
<output>db_dump.out</output>
<disabled>0</disabled>
</task>

the <cmd> should be executed from cronjob (starts from project root "test")

bin/status is ok, tells me update every 5min.

5 minutes 2014/02/01 21:44:24 unlocked no
db_dump -d 2 -dump_spec db_dump_spec.xml

But somewhere I have a mistake??? Any help is much appreciated!

The default supplied db_dump_spec.xml should work out of the box and require no changes. The output of the daemon can be found in the log_HOSTNAME/db_dump.out any errors will be there.

When executing db_dump manually you should first cd into the bin directory and then execute the cmd as specified in config.xml

You should check overall permissions and ownership of the directories in question.

Thx, ChristianB, was looking for the logfile but now found it. If I do manually bin/start --cron its working now but automatically every 5min its seems that the cronjob isnt starting or crashing.

With bin/status I can see "NOW" running but never stopped and no new update?!

Edit:
With bin/start --cron every is fine, without it its still stucking in running now mode but seems to be crashed without any log. This I can reproduce.

I would say this is a permission/owner problem. What user are you? Are the directories within /home/boincadm/projects/test owned by boincadm is the cronjob within the boincadm crontab and are you logged in as boincadm? You should answer all of this with yes. See Groups and permissions

Solution:
crontab -e was missing, thx for help ChristianB!
