du -sh command hangs


hi,

I am using RHEL 5.7 , problem which i am facing is when i use
du -sh <directory path> command it hangs without showing me the size to that particular directory. Kindly assist me how i diagnose that why its not running and not taking size of this particular directory. Is there any locks on directory which resist me to run this command?

[root@racnode1 grid]# du -sh /u01/app/11.2.0/grid





Thanks

probably you only need to wait a bit longer. Or even longer.

pan64 is correct. The command is likely not hanging; it's busy.

Try running du with and without the "s" argument and compare the times it needs to run.

if you want to be sure execute: strace du -sh path > result_file
and you will see how it works.

command is not working on that particular server.

[root@racnode2 ~]# strace du -sh /u01/app/11.2.0/grid >/tmp/out.log
-bash: strace: command not found

Hi there,

Is this directory and all its subdirectories on local/directly attached storage? If there is a subdirectory mounted via NFS/NAS, that may play a role.

If everything is on the same storage, the most likely reason for the long delay in getting the result for the next directory is a very large number of files in the directory. Do you know whether that might be the case for any of these subdirectories?

I'm inclined to agree with pan64's original recommendation: simply wait even longer ;-)

You can always try and build it from source - https://sourceforge.net/projects/strace/.

hi,

This directory is on local file system under / sub-directories basically contains oracle software installation binaries. Total size is 6.4 GB , Same directory structure install on another machine when i use du -sh command it shows me result with few seconds but on that particular server it hangs seems to me some process stuck which resist this command to execute.
Actually i am trying to execute a nodeadd oracle script which will copy this folder and move to the new server . But that script hangs for several hours when i check du -sh command on that folder it also hangs. so i feel some thing wrong on os side which is not allowing me this operation.

Thanks

strace is a standard package with RHEL5.7. So you either don't have a RH Satellite for package management or you don't have an active subscription too or both. You other option would be to setup a local repo, however you will need the DVD or ISO for that.

Since you state that all files are local, how about giving us a breakdown from /? Why so fixated on using that command, lets try something else?

Code:
# df -haT

Also if you run either top or ps aux, show us the output here and please use the code tags so it is easier to read.

Or if you are stating that this is Oracle, you could use the lsof command and look at standard Oracle ports:

Code:
lsof -i:1521

lsof -i:1158

One other thing that will hang du is a bind mount that creates loops. This could have been done by accident.
