Say you are in a work, lab or other environment where you are not alone on the physical network and there could be overlap of IPs, but you need all of your VMs to be contactable from your host, VMs need to communicate with each other, and VMs need internet.

This created problems trying to unmount it or even to stop this array with mdadm freezing. As for how to fix it I can only think of making sure you are not in a mounted path of........

My Samsung drive failed on me, at first I thought it was the enclosure but a direct SATA connection causes the same problems for discs that are inserted. It will work fine for a few minutes but then starts spewing the errors below. I've never been a fan of Korean made optical drives and have always had trouble with them. The problem is that I don't believe NEC and Lite-ON make drives anymore, and I considered them the leaders. Apr 7 11:58:48 bo........
