extending file system
 

Hello:
We have Linux 2.6.18-194.el5 #1 SMP Mon Mar 29 22:10:29 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux system. We are using NetApp for storage. We wanted to extend a file system from 200G to 300G. We extended the volume and the LUN but the file system is still not showing the new size when I do df -k. What are we missing? Thanks for your help.

You need to increase the size of the partition as well. Depending on the distribution the default tools to do this via a gui will be different. Command line I'm not as good with as I should be so try looking up the man pages of mkfs.

Thanks. I will give it a try.

What did you use originally to format that volume?

Show the output of the following commands...

Unassigned is just "tag" name, but that does't mean that is the free
space.
You just run mount command and compare with your slices displayed below.
Is all slices displayed below are mounted or not, if not mount and use.

Doesn't look like /dev/sdf was formated using LVM right?

Here is a good 9-page document on LVM that includes enlarging and shrinking volumes:
