Home disk quotas

In the near future, quotas will be enabled on the LEPP Unix home disks (/home/username). Up until January of this year, /home disks have had a quota of 512MB. After a system failure and an emergency move to a temporary backup server, quotas were disabled. When we move our /home disks to their final location in the next few months, a quota of 1GB will be implemented.

Because home disks are widely used by everyone (login scripts, desktop profiles (gnome, kde, etc.), firefox profiles), it is important that we minimize their usage. An outage or saturation of the home disk has wide implications and adversely effects all Unix users. In general, any personal, group, or project data should be stored in user, project, or group file systems instead of the home filesystem. Please see DataStewardship (https://wiki.lepp.cornell.edu/lepp/bin/view/Computing/DataStewardship) for more information.

Before quotas are implemented, we will be contacting users with over 1GB in their home disks and assisting in moving their files to an appropriate location.

General network and server maintenance will occur every Tuesday from 12:00 noon to 2:00 PM. The CLASSE-IT group will always announce any expected disruptions in our NewsLetter and via CLASSE-IT-NEWS-L, but with the size and complexity of our network there is always the potential for something to go wrong. We will do our best to contain all network maintenance and planned outages to Tuesdays from 12:00 noon to 2:00 PM.

Unless other arrangements have been made, CLASSE-managed Windows systems may be updated and rebooted on Tuesday morning at 2:00 AM, so please avoid critical or lengthy operations at that time. For more details, please see SystemExpectations.
