release the space

[hangyu]

I have move some file from a volumn to another volumn , then I check by bdf and found that the space is not release ( that mean the used size is the same ) , except reboot the server , how can I release the size ? thx

The process which has that file open is preventing the space from being released. You can determine that with fuser or lsof.

You can get lsof from the link below, if you do not have it

Shalom,

Even when the file disappears, the space is not returned to the system until all process file handles are closed.

fuser -cu /filesystem

# lists the processes. If you want to kill the proccesses at a k to the options. This can disrupt normal system operations.

Hi:

From your description it sounds like you have a process that has a file open that has been otherwise removed. Until the last process using the file terminates, the space used by the file will not be released.

To identify the process use 'lsof' (available from the Porting Center):

http://hpux.cs.utah.edu/

Do:

# lsof +D /path +L1

Look for a 'NLINK' count of zero (0). This represents an open files that will vanish as soon as the last process it terminates.
