Today I worked on installing the actual cluster nodes, and it worked out as well as I hoped! When they’re installed this way it’s easy to screw them down and they are quite solid, not gonna move.pic.twitter.com/EJjzraOWmt

(You might notice the damned screws are FLATHEAD. These were 1/2” 6-32 screws I already had, but being flathead they’re obviously garbage. The screws I ordered today are 1/2” 6-32 Phillips and as I un/re-mount units for testing, I’ll replace their screws.)
With the 1/2” screws I can easily loosen the cluster nodes without having to completely unscrew them from the back boardpic.twitter.com/w2sYVoB2yn
Also attached the switch and router today, which means...
I’ve attached all the components!! Currently that means only 4 cluster nodes with empty slots for 2 more. This is SO exciting, it looks how I planned it and everything is solid... even with some mistakes, the plan worked!!

What is this going to be? Collect all these threads into a higher order thread?
Yeah, I guess I never actually laid out the end goal here. Gonna be a lizardfs cluster made of odroid HC2 nodes. The idea is that it’ll be easy to add/upgrade storage by just adding/replacing a node.
Right now all my time is going into getting components laid out and connected up, which has involved learning a bunch of new things as I’d never used tools like a dremel before
NAS? Cool! What are you storing if u don't mind me asking? This is pretty cool.
Well, I started this as an experiment, thinking that if it worked super well it might be a good way for people with lots of data storage needs to add semi fast storage to a pool that can grow indefinitely
Is there RAID like fault tolerance of individual components? I really want a high level overview! But don't feel pressured to make one r.n. if it takes you away
Yes! I want it to be as fault tolerant as possible - right now the design is missing fault tolerance only on the network boot system (which could be addressed easily) and the conserver system which lets you connect to each node over serial (maybe not possible to make redundant)
With lizardfs you can do complicated stuff like have different redundancy and parity for files in different directories too.
