re-sizing existing partition on RHEL 4
 

Hi,

We are trying to install oracle in /usr partition but we need to re-size it to add more space from log partition.
We need help on how to achieve this task




This is a copy of df –k:


Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
5160576 2202436 2695996 45% /

Thanks For the help

I'm sure you will find a good walkthrough on the net somewhere, but this is basically what you need to to:

1. Unmount /logs
2. Run disk check
3. Reduce file system on /logs (resize2fs)
4. Reduce logical partition (lvreduce)
5. Increase /usr partition size (lvextend)
6. Increase /usr file system size (resize2fs)
7. Mount /logs

Hope this helps. I must warn that I haven't done this myself, but I'm pretty sure this is what needs to be done.
