Cannot write to tmp directory file corruption even if there is space available? Follow step by step to solve such issues.

Sometimes particularly if the /tmp directory gets full on your server, the underlying tmpDSK file can get corrupted. If this occurs you will not be able to write to the /tmp directory even if there is space available.

To fix this do the following:

Login to your server via SSH then type the following commands:

lsof /tmp   

umount -l /tmp 

umount -l /var/tmp   

# This command removes the corrupt partition file 

rm -fv /usr/tmpDSK   

# Create a nice new one 

/scripts/securetmp

If you wish to increase your tmp directory size, you can change the value inside the /scripts/securetmp file before running it - search for $tmpdsksize
