further nebka questions
by Christian Zimmermann 01 Feb '08

01 Feb '08

in the root crontab, about the follozing entries (currently commented out by me): #CZ30 0 * * * /root/check.tables #CZ22 23 * * * du -cs /* > du_slash_`date -I` #CZ23 22 * * * du -cs /home/aras/backup/* > du_home_aras_backup_`date -I` #CZ27 22 * * * du -cs /home/aras/acis/* > du_home_aras_acis_`date -I` #CZ33 22 * * * du -cs /home/* > du_slash_home_`date -I` #CZ36 01 * * * du -cs /var/lib/mysql/* > du_var_lib_mysql_`date -I` #CZ39 01 * * * du -cs /var/* > du_slash_var_`date -I` Are they any good? The machine crashed twice after du -cs /* > du_slash_`date -I`, as far I can see, and I just tried du -cs /home/* > du_slash_home_`date -I` which took several minutes with full load, and the machine was not responsive for a while after that. This worries me. Christian Zimmermann FIGUGEGL!

nebka update
by Christian Zimmermann 30 Jan '08

30 Jan '08

Still up, and I manually test each of the crontab entries before uncommenting them. Soon, I'll have everything working, except anything related to CitEc. disk use went overnight from 84% to 76%. I have not seen it so low for a long, long time. Is it because there have been essentially no logs for ten days? I noticed that /home/aras/acis/bin/updareq RePEc / takes a very long time (CPU and wall time), and it is performed daily. Wouldn't it make more sense to be more selective, i.e. only on material that changed? I am running /home/aras/acis/bin/updareq ACIS / now. What is that good for? Christian Zimmermann FIGUGEGL!

I just got three authors signing up? How is that possible? authors.repec.org is still pointing to repec.econ.uconn.edu, right? Well at least nebka seems to be working under live conditions...

nebka up
by Christian Zimmermann 29 Jan '08

29 Jan '08

Tim seems to have put nebka back online, and it seems to be spewing out emails. I will comment everything in crontab and kill whatever is running to let us investigate the problems.

nebka, further proceedings
by Christian Zimmermann 27 Jan '08

27 Jan '08

Here is what I suggest once the backup is done: Tim, give ssh access back, so that we can check what happened. Ivan and/or Thomas, have a look at logs Thomas, slice up any rsync so that it does not synchronize large file structures. I strongly suspect that was the problem. Saturday, I will be on my way back to the US. I should be able to get back online at 8:00pm EST. I will be back on campus Monday, and can go in the machine room if necessary and thus relieve Tim from this. Christian Zimmermann FIGUGEGL!

Any news on the nebka front. I just gave a talk at the OECD, and people there knew the machine was down and enquired about the situation... Christian Zimmermann FIGUGEGL!
