Proxmox/OpenVZ Can’t umount (unmount) device or resource busy

21 May , 2013 No Comments Standard Post

Recently when working on an OpenVZ container I was attempting to create a backup. While doing so I kept running into a problem where the server wouldn’t let me unmount the container in order to create the backup. The error you may see in this instance would say “Can’t umount /var/lib/vz/root/OpenVZID device or resource busy”, or “Can’t umount /var/lib/vz/root/100: Device or resource busy TASK ERROR: command ‘vzctl umount 100’ failed: exit code 51″, in this case the container being 100. Here’s how I was able to fix it … (more…)

Do you love being able to search for any song on Grooveshark and play it whenever you want? What about creating a radio station from one of those songs? Google has just released their Google Play Music which will now allow you to stream unlimited songs, skip as many times as you want, and it only costs $7.99 a month. I can’t explain in words how awesome this is, but i’ll try. (more…)

Tutorial How to build the Ultimate Bootable Custom USB Flash Drive with Multiple ISOs for Windows, Linux, Etc, and PortableApps for Windows Desktop.

If you’re like me at all you probably have more flash drives than you want to carry around, especially when they could all probably fit on one. After my old 64GB flash drive took a dump I decided to purchase a new 64GB flash drive with USB 3.0 and compatibility for USB 2.0 and USB 1.1. When I got the new flash drive I was determined to figure out a way to get rid of my bulky CD case and just carry this one drive around with me. That means getting rid of all my Windows 7, Windows XP, Windows 8, Server 2003, Server 2008, Ubuntu 12.04, Linux Mint 13…I think you get the point. The problem is there’s no real easy way to create a flash drive that can store all of these, and boot into any of your choosing, and still be functional under Windows when using it for troubleshooting or repairing workstations…until now.

How to build a reverse “mux” headphone splitter (2 inputs, 1 output)

So i’m sure you’ve seen those Y splitters you can purchase online that are used for instances where maybe you want to have two headphones hooked up to a phone or laptop…but what about when you want to have two outputs going to one input? You could in theory just hook it up in reverse, but then you are risking damaging those devices and i’m sure you don’t want to ruin something worth hundreds or thousands of dollars just to save a couple bucks. Say you want to have your laptop and desktop connected to your speakers…but the speakers only have one input, that’s the idea behind this…you can purchase switches out there that require you to manually change the input, but that wouldn’t work for me. So here’s how I built my own for only a couple bucks… (more…)
