I use Redhat 4 system , in my server , I have run some process , gzip file , remove files and run some routine tasks .

It is strange that I use the command "du" to check the system available size , it seems there is space is "disappear" - the total system server size is 1T , the available size is 300G , but the used size is just 500G , that means 200G is disappear , the error happens when I gzip the files , but I use lsof , fuser can not find related process , I use ps -ef still can't find any related process , except reboot , how the space can be released ?

Thanks.

try fuser -m to find out the process id, and you will be able to kill it. Try also identify that process by ppid

I believe gzip uses some temp space whilst its doing its job, but it should clean up after itself.
If it had an issue, it may not have cleaned up properly.

( FYI, RHEL4 is no longer supported by RH, unless you pay extra for Extended Update support: http://www.redhat.com/security/updates/errata/)

tried to use fuser -m , the below is the output , can advise how to know what is such process ? how to kill it ? thx

You may find 'fuser -v' more useful http://linux.die.net/man/1/fuser
