The Nutanix install has been moving along. I would not say it’s ready for more than lab use, but it’s getting there. I’m setting up a 3 node cluster, and one of the nodes, which has an Intel motherboard, kept throwing a generic error about not being able to find the sysinfo. Thanks to the help from the forum, I was able to hard code a product name in order to get past the install. I don’t think it will have an impact on operation, only install, but it’s one of those little things that crops up with new software.

About 2 months ago Nutanix.com released a free software only version of their magic, called Community Edition. I got on the list for this as quickly as I could, but I haven’t been able to install it until now. See, I wanted to have an actually cluster, what the call RF2 (Redundancy Factor), which would require me to blow away my existing XenServer install to get to enough compatible hardware. I also needed to purchase SSD’s for each of the nodes in the cluster.
Well, I’ve done that now. At the moment, I’m exporting my VM’s out of XenServer to OVA’s, in the hope I can restore them from that. If I can’t, well….I’m not sure then. I may just rebuild everything from scratch. I’d really like to figure out how to import them, though.
What I’ll have when I’m done is a 3 node RF2 cluster, with the minimum a 240GB SSD, and at least a 500GB HDD in each node. All 3 nodes are i5’s, of different vintages. Not a lot of space, once you run the Nutanix overhead, but it’ll be enough for my needs. I’ll post some screenshots and pics once I’m up and running.
In the interest of completeness I’m posting my pictures here to show what the inside of the GXV3610 looks like. I couldn’t find this anywhere else, so here it is:
My goal was to remove the cable from the backside of the ball and run it through the small hole I had already drilled through the exterior wall for a Cat5 cable. The two sides of the ball unscrew easily enough, but you can see from the pictures that getting the cable out would have been a challenge. The wires coming out of the jacketed cable go to three different plugs. I could have made that work, although the weatherproof grommet at the back would have been a problem. The bigger issue is what the red arrow is pointing at in the second pic. That’s the mic at the front bottom of the camera. Or rather, that pair of wires goes to the back side of the mic, which is thoroughly coated with a white paste of some sort, no doubt for weather proofing. My only real option would have been to snip those wires and resolder them. Nah, that’s ok.
Instead, I went to Home Depot with the mounting ring in hand and found something like this:
The ring does not line up with standard 4″ round electric boxes. However, it’s a perfect match with this junction box. I had to add some caulk and foam backing material to seal the gap, but it’s closed tight now. I’ll snap a picture of the mounted box and post it.
The camera is working great. Good FOV and sharp picture. I have the 720p model, not the full HD.
My 700e security camera failed after a couple years of use. I got a Grandstream replacement, which I’ll also post about, so I figured it would be good to take the 700e apart and see if I could figure out what went wrong. Figure it out I did. And since there’s a lack of documentation and photos for taking the thing apart I thought I’d put it up here:
First, pop the top silver cover off by slotting a screw driver down the side to pop out the tabs:
Once the silver cover is off you need to remove the 6 screws across the top and gently insert a small flat head screwdriver here:
All you’re trying to do with that one is break the seal. After the seal is broken the darker color cover comes right off and you have this:
Bonus points if you can guess what my problem was:
Remove the screw from the metal plate at the ethernet jack end. Carefully pry up the circuit board from that end. There’s also a slot on the plastic end plate that you can use to help it up. Once it’s out you can carefully raise the board up on the angle, although the cables going to the camera board are still attached. Here’s what I found under there:
Yep, that’s white corrosion all of the top of the Ethernet jack, the lower right corner of the board, and all around the edge. Just below the (I think) transformer on the right there’s a bright white spot. That’s actually a pile of corrosion on top of several resistors.
So, there you have it. A disassembled Logitech 700e security camera. I’m going to try an eraser on the corroded bits and see if it wants to come back to life. I’m not optimistic, but I’ll post back if it works.
No matter what I did I could not get a stable NFS connection to Unraid. The stale file handles problem was a continuing source of issues with Plex running on Ubuntu. I just switched to SMB and it seems to be working ok. I’m having some pausing on high bandwidth content, but that might be the wireless network. I’m not sure yet. Regardless, here’s my fstab now:

And yet some things stay the same. I’m returning to IT consulting next week and I’m very excited to be doing this! I gave the corporate job 3.5 years and while I thought it was good for getting that type of experience, it never really fit well for me. I can’t wait to get going!
As of August 11th, 2014, I am a college graduate. 24 year senior, or something like that. Anyway, I’m happy to be done with it, but I can’t say that it feels like much of anything. Just need to keep moving on.
I just finished another semester of school. I came very close to saying I aced it, but unfortunately I was one grade away from that. That’s ok. I’m in an in between week now. On Monday my second to last class starts. It’s a writing class, which if you can tell from looking at this blog, I don’t do a lot of. It should be interesting, nonetheless. In about a month I start my last class. That one is the capstone. The IT class that’s supposed to wrap it all up and put a bow on it. Provided I keep the pace, I’ll “graduate” on August 10th. UMUC doesn’t do the walk until May. Not very likely I’ll be interested in doing that, but who knows.
More than anything I’ll be glad to have it done. I’ve spent a lot of time in my life getting certifications. Nothing like this though.
Just watched Person of Interest. Most of the time it’s easy watching, but this episode was powerful. We’ll done. Depressing. I’ve been watching the West Wing again and find it very inspiring, even if I disagree with many of the ideas. This PoI episode though, powerful in a bad way. Makes me fearful of government, where WW inspires me. It’s interesting to see the two sides of the same coin.
A couple of episodes ago on the Walking Dead there was a song that caught my ear. I looked it up and it was Blackbird Song by Lee Dewyze. Could be straight out of Firefly, for all you Verse lovers. Definitely worth the download.
