I have a SCSI disk in a server (hardware Raid 1), 32G, ext3 filesytem.
df tells me that the disk is 100% full. If I delete 1G this is correctly shown.
However, if I run a
du -h -x / then
du tells me that only 12G are used (I use
-x because of some Samba mounts).
So my question is not about subtle differences between the du and df commands but about how I can find out what causes this huge difference?
I rebooted the machine for a fsck that went w/out errors. Should I run
lsof shows me no open deleted files,
lost+found is empty and there is no obvious warn/err/fail statement in the messages file.
Feel free to ask for further details of the setup.
