UNIX for Advanced & Expert Users

Hi All,

Can anybody tell what is the reason
when I type df . the result shows as below
Filesystem 1024-blocks Used Available Capacity Mounted on
data3_domain#data3 35556784 31222753 3809472 90% /data3

so, in /data3 still 10% available to used, when I create a file with single line its giving the message "No space left on device"
unable to create a file.

Thanks
Krishna

Hi

If U use vi editor to create a file , it uses temporary files to process your activities. Default path for these temp files is either "/opt/tmp" or some some "tmp" .

Eventhough you are working in /data3 , you need to check the "df" for the above mentioned directory or change the default temporay file path to "/data3 " area in ".exhrc" file

Bye

df -k (gives you them all at once in a 'nice' format).

If you want to see if you can create a file on /data3, just use echo.

echo This is a test file for data3 > file.out

This will read from stdout to the file named...

Or you can use touch to just create a 0 byte file in the directory.

touch file.out

Also, check your /tmp and /var/tmp for available space as well.

I do beleive only root can write to a filesystem over 90% full.

As a user account you will be unable to create a file.

Are you creating the file as root?

halfling,

That is very interesting. I have never heard of that. Can you tell me where you heard that from and what OS it was referring to?

It is hard for me to believe that is the case now. If a user has permission to write to a filesystem, why should they be restricted at 90%?

This could have been setup with Quotas. Can you provide more information on this?

Thanks!

That is way unix has worked for quite a long time. Do a "man tunefs" and look at the minfree parameter.

But df takes this into account. A ordinary user can use 100% of the disk as reported by df. root can run a disk up to 111%. I've seen that many times.

My guess is that the OP is out of inodes. No inodes, no new files.
