Bdf shows file system full but ll shows no file

[Ericsson GSC]

Hi,
When I am running a bdf on a file system then it shows it to be 100% full but when I try to do a ll on this directory path then i see that there are no files.
What could be the possible reason for it.

[Rick Garland]

A possibly reason could be that an open file was removed (rm) as opposed to cat /dev/null > . This might clear up in time (short time) or you may have to reboot to reclaim.

As a precaution, if you are not sure if the file is open, do the cat /dev/null. If the file is open, you will see data populate the file not long after.

Hi:

One simple possibility is that you are not seeing 'dot' files; do: ls -al

bdf by default reports free space on all volumes. Follow it with a directory or filename and it will report the free space on the volume on which the directory/file exists.

If you're looking for something to tell you what's hogging the space, you need to use du. Check out the man pages on both of these.

[John Palmer]

fuser -c will produce a list of processes which have files open in that filesystem. If you can identify the process that has the removed file open and close/kill it then the free space will be reclaimed.

John

In my opiniion, after removing files by using command 'rm', it takes some time to synchronize the file system information like 'bdf'. But I think it's not critical in system.

Another thing you can try is run the sync command one thing this is used for is to examine a file system , when doing (fsck,df etc..)
For more info do man sync

Hi everyone,
Thanks for your contribution.We found the problem here. The problem was becuase when you are having filesize larger than 2 Gigabytes on HPUX (probably all versions),
then you have to define it in fstab file.
This is what we had not done.

Is it an Oracle datafile ?

If so what happens is that the database still holds that space, I beleive the SMON process is the one that will clean it up eventually (either every 30 minutes or 2 hours). However I have seen it not do this, shutdown / startup of DBMS will cure it.
