Centos – Root file system is full and I need to install additional software.

centoscentos5filesystemspartition

I am trying to install to install EPEL Repository on CentOS 5.7.

I still have lots of space available on my hard drive. 

/dev/sda2             3.9G  3.9G     0 100% /
/dev/sda11             17G  2.9G   13G  19% /extra
/dev/sda10            996M   44M  901M   5% /logs
/dev/sda9             2.0G  670M  1.2G  36% /applications1

I just want to use some space from /extra so I can install mysql 5.5.20. Since I don't have physical access to this machine I cannot use CD and make partitions. There is no important data on this machine.

What is the safest way to do this.

This is the output of partition table

Model: VMware, VMware Virtual S (scsi)
Disk /dev/sda: 75.2GB
Sector size (logical/physical): 512B/512B

To be honest, you're going to be stuck here until you free up some space on /, or until you think of a way to chroot yourself in /extra. There are guides floating around on the internet on how to do that, since I've never actually done this myself.

That said, if you're using LVMs, you could resize / so that it's big enough to install some things on. However I don't think your setup has an LVM.

Also, I don't believe Yum can do relocatable packages (at least I've never needed to, someone feel free to correct me), and in this case it wouldn't matter until you at least free some space up on /. You could do a du -sch / to find begin finding out which directories you can delete from, though I don't think this would help since your / partition is small enough to presume that it's a basic install with a GUI on top.
