How to add space to /dev/mapper/root_vg-rootdir
Hello all. I had one of my programmers ask me to increase the space on the "/" directory. Coming from a windows background I didn't think this would be difficult but I have not had a good time with this. I've been able to increase the size within fdisk to include the space I added via VMware after some time. But now im getting stuck on how to add that space to the filesystem that "/" is listed under, in this case /dev/mapper/root_vg-rootdir.
When running fdisk -l i can see that ive successfully added the new space to /dev/sda5. You can see that here:
[root@slplaygroundt1 ~]# fdisk -l

And then you can see the files system im trying to add it to here:
[root@slplaygroundt1 ~]# df -h

Ive been pouring over documents, red hat related and not but iv gotten sorta stuck. Anyone have a clue or a pointer in the right direction?
