System Administration

How to set up, use and maintain disk quotas for your Linux system.
How Users Can Check Their Quotas

Every user or group can check their disk quota with the command quota. This command produces a report that contains information for all file systems listed in the /etc/fstab. Give the command quota -u (for user quota) or quota -g (for group quota) or a combination to obtain this information. If no quotas are set, the command quota -u results in the following output:

Disk quotas for dsnjaro (uid 503):none

If quotas have been set, the output looks like:

Disk quotas for user dsnjaro (uid 503):
File system blocks  quota  limit  grace  files  quota  limit grace
/dev/hda3   49   100   110       30    0    0
Only the system administrator can use either of the commands:
quota -u <
quota <-g <group-id>
Quota is working very well for me in my work, where there are approximately 300 users on our system.

Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
