Low Disk Space

Peacefrog10 · 07-27-2009, 10:36 AM

Hello,

Newb here, I have Linux Red Hat Enterprise 4.0 running as my mail server and I am getting errors that I am out of disk space. For example if I try and drop a file on the desktop I get an error that there is no enough space available. I recently deleted some old RPM packages from the Update folder and uninstalled openoffice as this server is not used for anything but my mail server, and I still get this error. If I open the file system it says 0 bytes available. I'm not sure how to tell how much space is available on the partition or if its configured somehow as to only allow a certain amount of available space for certain folder. Any help would be greatly appreciated

After doing a # df I can see that Dev00 is completely full.

Hi,

Welcome to LQ!

You could use 'df -h' from the cli which will identify the space on the disks in human readable format. You could then see where space can be recovered by deletion of files that are no longer necessary.

thanks, entering that command from terminal shows me that I have 63 of 65 gigs used, but how can i see what is taking up what as far as space is concerned.

There are several methods you can use to determine what is taking up space.

If you have root access you can run this command:

Quote:

du -m / | sort -n -r | head -n 10

That will sort the directories starting at the / directory and list the top 10. Also the "find" command with various flags and options can be useful.

~#df -h
Filesystem Size Used Avail Use% Mounted on
/dev/root 94G 5.1G 85G 6% /
/dev/sda1 30G 9.4G 20G 33% /mnt/winxp
/dev/sdb1 39G 4.3G 34G 12% /mnt/winxp2
tmpfs 876M 0 876M 0% /dev/shm
/dev/sda6 9.4G 746M 8.2G 9% /mnt/gws
/dev/sdb2 38G 32G 3.7G 90% /mnt/Linux_Archive
/dev/sdg1 3.8G 332M 3.5G 9% /media/STORE N GO

The above output shows that '/' used 5.1GB with avail 85GB. Now if you want to get specific within '/' then you could use 'ncsuapex' method or even 'find'.

But 'YOU' will need to decide what can be safely removed. As a user then '/home/user' would be a good place to start.

Thanks.

This is the drive in question

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00 65G 62G 0 100% /

I'm not sure what I can safely delete.
