[ILUG] Missing space

[Niall O Broin]

I have two boxes, each running the same disro. and kernel, and about 
the same workload (one is a standby for the other). But yet I have this 
on the active box:

Filesystem    Type   1M-blocks      Used Available Use% Mounted on
/dev/sda5     ext3       17319     15801       638  97% /

and this on the standby:

Filesystem    Type   1M-blocks      Used Available Use% Mounted on
/dev/md0      ext3       17319     16049      1271  93% /


The active box has just been rebooted, so the mystery missing space 
shouldn't be a question of deleted file blocks still in use, or an 
application preallocating loads of space. Anything else I should look 
for?

Note primary box IS scheduled for replacement, but needs to go on for a 
little bit longer, and disk space is becoming an issue.
