Filesystem full error

[bakyaraj]

When i check / fileystem for space using df -h it shows 100% full but it utlilized only 25 % of that filesystem.

/dev/mapper/VolGroup00-LogVol00 113G 108G 0G 100% /

/dev/mapper/VolGroup01-disk 10997G 4061G 6378G 39% /new/disk


And i have verified all the directories inside / partition, it utilized only 26G. And there is no hidden files or directories inside the / partition .
Dont know what is happening.

Kindly help me on this.

Thanks.

As a guess inode list full (df -ih to check)?

/dev/mapper/VolGroup00-LogVol00 30M 175K 29M 1% /

du -x / | sort -rn | more is my favourite command to find the directories consuming the most space.

Perhaps you have some processes which are still using some removed gigantic file. lsof -n | grep -i del may help in that. If, for example, you see that httpd is accessing a deleted error_log file, try restarting the service with service httpd restart.

Thanks avij,

Yes that command shows very big list.And it is a TSM server. It was restarted before.
But it shows again

... and?

If you run that du -x / | sort -rn | more command, what does the top line say? Is it something around 108 gigabytes or 26 gigabytes?

What method are you using to determine that it's only using 25%?

[bakyaraj]

Hi avij,

It shows in the first line.
110497026 /

The result of that command.

Hi TrevorH

I just checkd with du -sh /*

and it lists only two directories are in GB. its nearly 26G

[TrevorH]

Run this as root and post the output

Code: Select all

du --max-depth=1 -x -m /

The directory that is listed there that takes up the most space is where you need to look next. Repeat the command and change / to /whatever the directory is that uses most space. Keep doing that until you reach the bottom of the tree.
