Root Disk Increase!!!

[ponnpr7]

Hi,

Could give me some direction how to go about root partition increase and still growing I'm taking a step ahead to extend the root filesystem.

Please advice.

I have this root filesystem getting full, do I need to do any kind of permission change to the file system once I do the disk resize

[root@nagiosxi ~]# pvresize /dev/sda5
Failed to find physical volume "/dev/sda5".
0 physical volume(s) resized / 0 physical volume(s) not resized

Based on the info above, why are you doing something to /dev/sda5 ?

Did you try the "Automated With Script" method from the document above?
