Incorrectly reported filesystem size

[Steve Boulding]

We have had a few recent instances of filesystem utilisation being mis-reported. For instance a bdf would show a filesystem being at 99% full, even though it was only actually 5% full. All these have been resolved by unmounting the filesystem. Is there a reason behind this and/or a better solution?

Thanks

This sounds like the old issue of a file being removed/unlinked while a process still has it open. Unmounting the files system and remounting fixes this, but a process having a file open will usually stop the umount. More often, th e process terminates, leaves the in-core information there, and then only gets fixed on the umount/mount sequence.
I suspect a bad application or script here.
