Hi all,

There is an NFS share on linux box and it is getting filled very fast. It is filling hundreds of GBs everyday. How can i find what is filling up the space ?
thanks in advance!

du -sh /path-to-device/*

Also
lsof |grep path-to-device

I prefer ncdu for such tasks. It should be available for almost any distribution and is quite handy, since its interactivity really can (and does) speed up to find the culprit.

thanks business_kid and TobiSGD,

will "ncdu" work on CentOS5/RHEL5 ? because i can't see it there on the ncdu page link.

There are packages for ncdu: http://pkgs.org/centos-5-rhel-5/atom...86_64.rpm.html

Hi TobiSGD,

sorry my bad, i tried to install 64bit rpm on 32 bit. i installed it now

Code:

# rpm -qa | egrep 'atomic|ncdu'
atomic-release-1.0-14.el5.art
ncdu-1.5-1.el5.art

and now HOW TO USE this tool ?

Just type

Code:

ncdu /path/to/your/share

It will begin to scan the path you have given to it recursively and displays the files/folders sorted by size. Navigate with the cursor keys, delete highlighted files/folders with the d-key, if you want.
For more info type

Code:

man ncdu
