Assigning memory/space to folder(s)

an_sush · 11-17-2008, 05:31 AM

If I run df command to find the memory available and used, i see the following output:
$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda2 77G 51G 23G 70% /
/dev/hda1 99M 23M 71M 25% /boot
none 1010M 0 1010M 0% /dev/shm

Is there a way i can set memory aside for some drive? like if i want my /opt not to exceed say 10GB? Is it possible?

You can use 'quota'. Implementation example here:

If repartioning is not an option, you can create a virtual filesystem of size 10 Gbyte and mount it under /opt. You can find some details in this post. Do a backup of any existing file under the current /opt directory: you will restore the backup once you have mounted the filesystem under /opt.
