Unable to find the used space from / partition

[#1]

Hello Experts,

I have a problem with the root file system usage. Its 100% utilized and overall if i am calculating the used space with du -sk, then i am only able to get 140 MB (/ is 240MB) out of total allocated space.

How can i figure out the remaining used space is where utilized and remove the data, if not required.

Please suggesst.

Thanks & Regards,

Maybe you deleted a file that was still opened?

[#3]

How to figure out that and release the occupied space which may hold by those deleted files?

[#4]

Check with fuser -cu  and confirm any specific process access /,then kill those process.

Also go to directory by dirctory confirm any file exist.

You may have to install lsof to find the process and kill it.

fuser -cu shows many process but output is not accurate and related only to root user. killing those process may turn in to bad decission. Checking on lsof suggession.

Thanks for your reply.

lsof didnt work here correctly, however i got the solution to extend the root filesystem without downtime. Its an online method to extend the root file system which is possible if your all LVOL's of VG00 are mirroroed in two seperate disks.

thanks guru's.
