Grow VDI Disk (VirtualBox)

Error: Acquire running lock failed: 256

Recently had a OVS root file system fill up due to a run away iSCSI process (and I don’t even use iSCSI…).

This one bit me in the proverbial recently. Was trying to setup phpmyadmin for a client on a different host to the database. This was installing apparently successfully, but failed after that. I hacked the installer code to and finally figured out that it was grant rights to the user@hostname (not user at IP address). So I changed the installer to lookup the IP and insert this. This got everything installed, but I was still have some other weird issues. Read more
