HI Rick, Thanks for your time but I am already aware of what you have stated, I am more ,about my other queries, i.e --Remove/reload/wipe process who's ps output comes with D+ stat
You really can't. A process in a D state is in an I/O wait state. Until that I/O is satisfied (disk, network, keyboard, whatever), the process will remain. The only way out is to either give it the I/O it wants or reboot. Sorry.
--How to trace running script/process , were it is blocked/hold (basically exact line of script), (any combination of linux command)
You can use the "-p <pid>" option of strace to attach to and trace a running process.
--process/users details of using resource ( disk partition, memory, files, etc) .(other than fuser)?.
Have you looked at ac/accton/last/sa and their kin? Brief HOWTO: http://tldp.org/HOWTO/Process-Accounting/index.html Also have a look at sar and it's bits and pieces. Note that bottom posting is preferred on this and most of the other Red Hat/Fedora mailing lists.
It will be a great help to me if you (or any one) can provide me a pointer regarding the same. Btw, Thanks again for your support. --Alok On 4/10/09, Rick Stevens <ricks@xxxxxxxx> wrote:alok pandey wrote:Hi Recently I experienced a problem on one of user-desktop machine (centos5.2), when a user(with all access) deleted the file /var/log/messages to free some space (as df -h was showing /var 100% full), but still df -h shows 100% full. It takes around 10 min to figure out the problem. To resolve it, I just reloaded the syslog service. ( I was luck that user told me what he did before, otherwise I am sure it will take min of 1 to 2 hour ) I want to know that is there any way to get perfect details of such misguiding output. (one i know is fuser, but i didn't find it's helpful). To be more specific about problem I want to know ,Is there any way in Linux(centos) to do the following :- --Remove/reload/wipe process who's ps output comes with D+ stat --How to trace running script/process , were it is blocked/hold (basically exact line of script) --process/users details of using resource ( disk partition, memory, files, etc) .When you free up space in a directory, all of the files in that directory must be closed before the free space will appear. As long as a program holds an open file there, the free space won't appear. In your case, syslog was holding /var/log/messages open so the free space was hidden. When you restarted syslog, it closed /var/log/messages allowing the true state of things to appear. It then reopened the file and life continues.
