i have a number of identical nodes with the same applications ruuning on them , so therefore, up until recently the files systems were roughly about the same size.
Recently on one node, the / has reached 94% used whilst in other nodes its only about 82%.
I have taken a look at / ( after ignoring other mounted file systems ) and I cant seem to find out what has 'eaten ' up this disk space.
The most common reason for / unexpectedly filling is a mis-typed file name for a backup device. This results in a large text file in /dev. This text file can safely be removed.

Another common one is having files 'under' the mountpoint directory. ie you have a mountpoint /blah and normally mount /dev/vgblah/lvblah to it. If you copy files to /blah before the mount command is run, then they will actually be on the root lvol. Once the proper lvol is mounted the files will disappear - but of course the space has still been used.
Do you have home directories in / filesystem ? You can have core, or log files from users or users applications .. Did you reboot this node ? Sometimes process can have open files on a filesystem, not completly flushed to disks, not seen by du, but taking space in the bdf ..
Hi, as long as /tmp is mounted seperately it will not count towards the / size.
Something else you could try is: find / -size +1000000c -xdev -exec ll {} \; | grep 2006
This will find all entries with more than 1000000 characters (approx 1Mb) on the root partition. The grep at the end does a very crude elimination of old file. You can try to change the 2006 to 2007 for this year.
