Disk Space Query

[Gary March]

I have a file system (/w) which indicates over 2GB usage when using bdf.

When I use the command "du -sk /w" it indicates it is only using 500MB.

Checking all directories under /w does not show any large unexpected files.

The file system has been around the 2GB size (via bdf) even after reboots.

Where could the missing 1.5 GB disk usage be...?

Hi Gary,

Do you have any process(es) that uses /w filesystem ? Check this out by # fuser -u

Hi Gary,

Can you paste the output of the follwoing commands,..

bdf -i
bdf -i /w
du -k /w
du -sk /w

A attachment of these outputs would suffice.

Yes, I have several hundred processes using the file system. "fuser -cu /w" shows these processes.

Please note that after a reboot, this count would possibly be zero.

Hello,

Can you kill all the unwanted process and post # bdf -l output.

Hi Gary,


My guess is U would have mounted a file system which contains 1.5 gb worth of data, hence making it disappear for the command du -sk /w to check. To make sure this possibility is ruled out I would like to get us the output of the follwoing commands.

bdf -i
du -k /w

Sorry for ambiguos reply,

I meant, u would have mounted a FS on a directory ..which conatained 1.5 GB of Data earlier to mount..so please give us the outputs..to indeed see if this was true..

Also Gary,

We wanted the output of just "bdf -i" without mentioning any specific FS.

That is we want the whole output.
Just

bdf -i
