We had a 32bit Ubuntu server that was getting pegged due to the lack of memory it was able to use when observium was kicking off it’s cron. So I decided to move Observium to a 64bit Ubuntu server.

Unfortunately when trying to run the poller, the following error appeared.

The solution was to go back to the old machine and dump the .rrd files to .xml using the rrdtool dump command. I found the solution on this article.

RRDtool: moving data between 32bit and 64bit architectures

However, since the files were located in folders, the code snippet provided wasn’t going to do much. So I just did it with my good old friend xargs, cause I’m lame like that. So I ran the following on the 32bit Ubuntu server.

Then I used rsync to copy all the data over to the new 64bit Ubuntu server. And then ran the following.

And Observium was back to normal! Yea!
