partition extending?

[vinmansbrew]

I have a server that seems set up odd. It was done by a previous admin, with no notes left. It is on vmware and has 4 drives. Why 4, I am not sure, as I said, no notes.
Anyways, I have part of it that needs to be enlarged. It is called /u02, it does not contain any var/tmp/root directories, so I think it is just a formatted partition for storage. Now, I "think" it is on device /dev/sdc1, and the partition is /dev/sdc1? I am pretty sure /u02 is not spread out across multiple disks. Now, vmware shows the disk size to be 310G, but fdisk shows it to be 279.2G.

So, my assumption is that I have about 30G just sitting there unused, would that be fairly accurate? Also, if so, I need to add about 70G more to this drive. I can easily shut it down for maintenance and enlarge the disk in vmware. How do I enlarge the partition itself? Provided my assumptions are correct? I don't think it is part of any lv or vg since extending with either lvextend of vgextend did not work. But then I may have typed thing incorrectly.

Maybe I just need a shove in the general direction.

Thanks

What's the output of fdisk -l and df?
What's the content of /etc/fstab?

1. Back up /U02
2. Back up /U02
3. Unmount /U02
4. in fdisk, note the exact start of /dev/sdc1. You should use expert mode and then print the partition layout.
5. Delete /dev/sdc1
6. Re-create /dev/sdc1 with the exact same start point, but using all the space available.
7. run

Code: Select all

resize2fs /dev/sdc1

8. Re-mount /U02
9. If any problems, restore the data from your backup.
