How to check how much disk space left?

thomas2004ch · 09-09-2009, 07:17 AM

I have a iPlanet Web-Server installed on RH-Linux. Sometimes (not always) as I send WS-request to the application server via this Web-Server I got error message as follow:

Code:

...
Tue Sep  8 11:32:42 2009 Temp Post File name = [/tmp/_wl_proxy/_post__28832_77]
Tue Sep  8 11:32:42 2009 Could not open temp post file '/tmp/_wl_proxy/_post__28832_77' for POST of size 2306
Tue Sep  8 11:32:42 2009 *******Exception type [WRITE_ERROR_TO_FILE] (Cannot open TEMP file '/tmp/_wl_proxy/_post__28832_77' for POST of 2306 bytes
...

I guess maybe the maschine/server has little disk left. So I want to check it.

The "df" command will tell you.

I guess du and df commands might work for you.

du - estimate file space usage
it usually tells you how big is a file, you can use it like du [file / folder]

df - report file system disk space usage
it tells you the usage and free space on a disk or file system.

Both are better with the -h option which makes it easier to read (MB instead of bytes for example).

Read the man pages for more info.

Apparently your '/tmp' needs to be flushed. You need to find out what is eating your file space on '/tmp' when you attempt the request(s). Look at your logs.

If you are the admin for this system then the '/tmp' space allocation and reclamation is not setup properly.

Hi Onebuck,

In case if you just want to check the file size, then :
du -sh
will help you. It will show you the size of the directory/folder/drive.

But, if you want to check the memoru usage over the partitions, then :
df -h
will help you.

And in case, if you just wanna see the detailed memory figures, then :
free -mo
will help you.

Cheers,
Kapil

Thanks! I'm aware of the commands you posted. The OP is the one with the '/tmp' space problem.
Apparently there are stale files filling the space.

I saw no reason to post commands that others had already posted.
