problem about root file system full

[lin.chen]

Hi all,
I got a problem about "root file system full"
bdf and df -k show that / is 99%

I have use following command to check,
find / -xdev -type f -exec ll {} \; >/tmp/rootfile
all the file caculate totally is 113M (60%)

du -sk *|sort -n
did not show there is some big file.
totally is 113M

I suspect the unlinked file issue,
crashinfo -unlinked <<<
I also suspect there are some files has been save in some mount point wrongly.
ncheck -F vxfs /dev/vg00/lvol3 |grep /home
did not show such files.

How can I do?I really use 60% of the root.
where is the free space?
Thanks a lot,Louis

Check for files (type f) in /dev. What typically happens is that someone mistypes a tape device name and creates a large text file in /dev.

Check for core files.

Check for directories that should be in a separate dedicated filesystem.

Hi

Can you umount /er

Check /.secure/...

if you have auditing started.

Stop it, edit /etc/rc.config.d/auditing to change the location of the files and after that start it again.

I intially use find and only progress though the root filesystem ( i.e. do not cross mount points ).

For starters: find all "file" types and look through list for core, or items in /dev/

find / -xdev -type f

Next look for files over 10MB, there should only be on or two.

find / -xdev -type f -size +10000000c
