When booting your K2000 Series appliance you might see a message like this screenshot on your K2000.
The message /kbox: filesystem full
means that the main drive on your K2000 appliance is full. The error is caused by the database trying to start, but because it cannot it shutsdown with this message and keeps trying over and over again
The cause of the problem is that you like created a bunch of backups or exports through the K2000 appliance (see screenshot) and when it rebooted it did not have enough disk space for the boot process.
You should still be able to browse with Windows Explorer to the \\ikbox\restore
directory and remove and / or delete some of the packages that are there and then reboot.
