Hi guys,

What could be the problem when an application reports Linux error 28  (No space left on device) yet when we do a df there are tonnes of free space? 

The application throwing the error requires around 500GB and the NetApp mount has 4TB so clearly space isnt the problem.

df -h:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sde1              20G  1.1G   18G   6% /
tmpfs                  63G  224K   63G   1% /dev/shm
/dev/sde3              20G  172M   19G   1% /opt
/dev/sde5              20G  173M   19G   1% /tmp
/dev/sde6              20G  8.7G   11G  47% /usr
/dev/mapper/lv1     3.9T  676G  3.0T  19% /u1
