Can't free disk space
I am running Redhat 9 and had just finished running up2date. I had not updated for a couple months so there were quite a few updates. After the process finished it was successful and I decided to reboot. When the machine came back up X didn't want to start correctly so I deleted the XF86Configure file and created a new one and that solved that problem, not sure if that is related. Now, for the real problem. I noticed through my samba share and later through Kdiskfree and df that my / partition is at 100% use. I was on my windows box, so through the samba share I deleted several large files in my home folder and potentially freed up .5 Gb. The problem is that no free space has been reallocated. df still shows 100% used. I started the system in single user mode and unmounted the drives, then ran a fsck. This found no errors. I also looked in lost+found just in case something had appeared in there. I have deleted files from the linux box and with df it seems the used space decreases but the available never changes from 0.
How can I fix this.
