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 uname -a: Linux server.name 2.6.32-431.1.2.el6.x86_64 #1 SMP Sun Nov 24 09:37:37 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
