Hi All,
We are running a Linux machine :
Linux testmachine 2.6.18-274.el5 #1 SMP Fri Jul 8 17:36:59 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux
We are looking for some space to put some big files. I then issue a df -h command and I have this result :
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_system-lv_root
16G 3.0G 12G 20% /

/dev/mapper/vg_system-lv_oemcc

So to me, I have 18Gb free on /opt.
But when I issue the disk usage command on /opt a : du -h /opt, it says that my directory opt is using 24 Gb of space !
928K ./emulex/rhel5/x86_64/lib64
936K ./emulex/rhel5/x86_64
784K ./emulex/rhel5/i386/lib
792K ./emulex/rhel5/i386
1.7M ./emulex/rhel5
1.8M ./emulex
du: cannot read directory `./bb': Permission denied
24G .
So I am a bit lost... Please help :-)
Many thanks.
