I'm really having a hard time to process these results on my Ubuntu server. I have a major problem with my JBoss server where I get FileNotFoundExceptions along with "No space left on device" errors. And I thought "maybe I'm out of disk space", and used df command to figure out how much I have left:
root@ubuntu1:/# df -h
Filsystem Storlek Anvnt Tillg Anv% Monterat på
/dev/mapper/ubuntu1-root
36G 13G 21G 38% /
none 2,0G 192K 2,0G 1% /dev
none 2,0G 0 2,0G 0% /dev/shm
none 2,0G 64K 2,0G 1% /var/run
none 2,0G 0 2,0G 0% /var/lock
/dev/sda1 228M 23M 193M 11% /boot
/dev/mapper/vgdata-lvdata
79G 9,2G 66G 13% /data
And as you can see, I have plenty of space left. And I also checked if I'm out of i-nodes:
root@ubuntu1:/# df -i
Filsystem Inoder IAnv IFria IAnv% Monterat på
/dev/mapper/ubuntu1-root

10486784 233945 10252839 3% /data
But then i used du:
root@ubuntu1:/# du -s -h /*

Notice that /data and /eniro are 30G combined! How is it possible? Do I have a memory leak somewhere? Or is it something else?
----- EDIT 1 -----
Ok, I figured out that /data has its own mount so it's not possible to combine /data and /eniro because they aren't on the same mount. But how come it says 9,2G on the first command when it says 19G on the third on directory /data?
