During the next days, we will run a filesystem integrity check on all machines. This means that all machines will experience a minor downtime (less than 10 minutes for most machines). Technical contacts will be informed about the individual times in advance.
The global filesystem check is a preventive measure to ensure that we will not run into problems during the upcoming OS update.
A few machines in the development network showed incongruent filesystems under certain stress conditions. Although we did not notice any current problems in the production network, we identified some scenarios that could be triggered by the OS update process. The integrity check will effectively remediate any of those potential problems.
We apologize for the inconveniences caused by this safety measure.
