Hi All.

I have a question. Within linux, I would like to have a cron job monitor disk usage on a system. If the file system reaches say 85 or 90 percent available capacity, or some number of MB, GB, TB, or whatever watermark I choose, then I would like to automate the adding of new storage. The backend would be a NetApp, with previously created LUNs waiting in the wings. I don't need to grow a file system per se (or I supposed that would be answer, but not necessarily the best). One thing I thought about was to add them as a subdirectory to an existing directory. I realize that LVM could be used, but is there a simpler way? What ways has anybody done? Any help is appreciated. Thanks!

Hi,
u cam definatly create script for this. just make a script which will check your disk usage with a priodic time. take the o/p of script in a file . if it is some % of disk space then u can do atomated another script to resize your volume, like this
df -h this will give amount of space occupy.
use if loop to check your % of usage.
if it crossed the limit make a file or send mail to administrator.
then either u need to run lvm command or u can make another script for the same.

thanks
