Figure software RAID under Ubuntu is good enough (?)

software raid works but it requires some more knowledge and care.

I had troublesome experiences with soft RAID under Linux (it was Suse at the time, not Ubuntu). On the other hand, zfs treated me very well. 3 hardware disk failures got recovered without a single glitch.

Quote
I like the HP ProLiant MicroServers. 4 drives and nice remote management.
I have one of those, too. Definitely like it a lot. Going to get myself another for media files later this year. It keeps a decent temperature even in hot weather, which can't be said of some of my custom rigs. The remote management is quite nice indeed. Only drawback I've found: it's really slow to boot, but if you don't take it down daily you will barely notice. By the way, my unit runs FreeBSD/zfs. With timed snapshots and whatnots, I feel safe.

I can't speak highly enough, or more practically recommend, Synology products, over any alternative, for media/file serving.

Run two of their NAS' in my house and they are fucking bulletproof. Rebuilt/expanded their original volumes a couple times now as my needs grew, with minor issues (worst case was I had to ssh into a box, and manually shutdown services before fscking the main volume, to resolve issues that prevented me from further expanding).

Do you think it can be done? Any caveats, gotchas, likely pitfalls etc?

Along these lines, I'm looking to build myself a "proper" server to run Bitcoind and LND. Ideally RAID 10 for the boot volume, and RAID 10 for the blockchain/LND volume.

Figure software RAID under Ubuntu is good enough (?)
I would suggest a dedicated NAS with zfs (FreeBSD). Mostly like RAID, only better.
A dedicated ethernet cable between server and NAS would provide adequate disk bandwidth. Or, likely, you could actually manage to run bitcoind and lightningd on the NAS itself. As for the form factor, there are dedicated cabinets that accommodate 1-12 disks, with little leftover space except for the motherboard.

Why on earth would he need dedicated NAS for a shitty 150GB blockchain? The whole point against big blocks is not to be forced to run beasts like this to enjoy the full node.

My 0.02$: Bye 4 SSD disks:
- Two 128 GB for the system, in Raid 1 (mirror), Linux software raid is recommended. If you want to go fancy take those M.2 disks, double the speed then regular SSDs, but you don't have to.
- Two 512 GB for the blockchain, also in Linux Raid 1 (mirror). You can go for 1 TB versions if you don't want to change disks next 10 years, but they can go up to $450-$500 each for quality brands. Intel and Samsung are head above the others by reliability.

Any decent modern I7 or Xeon processor will be more then enough. You can go much, much lower, but you don't have to, they are relatively cheap.

Be picky on the power supply, if you want to spend more money on something it should be some server housing with redundant power supply and server motherboard already in it.

I think it’s the requirement for an “always online” connnection. Just easier with cloud. 

Don’t ask me to explain what happens if your node goes offline.  I don’t know.

It enables each of your channel counterparts to broadcast transactions stealing the value you have locked up in that channel, for one. Amongst other ills.

A friend whose opinion I highly value also has lots of praise for Synology. However, when he saw my units he fell in love with the HP and got one little later. I'm sure they make good products, but they have proprietary software, and that's a show stopper for me.

Alright.

Fine.

I'll look into the HP units again.

I'm sure they have a "premade" solution that will be fit for purpose.

Asshole.

It enables each of your channel counterparts to broadcast transactions stealing the value you have locked up in that channel, for one. Amongst other ills.
And gives said counterpart the chance to have their whole assets on that channel forfeited by you if anyone snitches on them within a week. I wouldn't try that.

By the way, the phrase you wrote and I underlined could be read as meaning that there are several counterparts per channel. There are only two actors for each channel: yourself and the other end (counterpart).

Can anyone recommend a decent i7 or Xeon based system, smallest form-factor possible, capable of housing at least 4 x 3.5" drives ?

Amazon and NewEgg are kinda a crapshoot... Maybe I should post this in another thread...

A i3/i5/i7 and a good SSD with a big write durability is fine.

These CPUs have higher clocks than xeon (some tasks in bitcoin perform better with higher clock speeds because they are single-threaded, and you see that during rescanning/reindexing) and they're also cheaper.

I also propose SSD because HDDs* are way too slow for constant accessing throughout a 200gb database. It's not their MB/sec that are lagging, but their access times - which cripples them when doing random reads and random writes to something like 1 mb/sec....

And obviously, since SSDs are 2.5'' or even smaller as M2 extension cards, you can make your form factor even smaller, approaching a very small box, or even a laptop. Some laptops have 2 disks (1 M2 + 1 x 2.5'') and if you have, say, 2x500gb, you should be ok for at least the next 2 years.

I'm also curious where BTC will be at the end of 2018?

As are we all.

Somebody did a monte carlo simulation based upon a random sampling of daily returns. The center of the probability distribution function was $55.5K.

$55,530 center of distribution
Probability of less than $13K - 9.84%
80% confidence interval: $13,200.00-$271,277.00

You can quibble with the validity of past returns used as a basis for future predictions, but its one analysis.

These youtube technical analysts experts are really pissing me off, now everyone knows BTC is going to 8k or even less and everyone will buy back right at the bottom of the dip and nobody will sell at the bottom at 8k or below, yeah right everyone will do well if they listen to those no-lifer high school dropouts that got an opportunity to actually have any audience once in their lifetime, got only one question for them - how long did the last flash crash last (july & september) and how big was the rise that followed after everyone bought theirs coins back?

Segwit, LN, Big Blocks, Satoshi vision, Blockstream, Core, and much more:

https://github.com/bitcoin-dot-org/bitcoin.org/pull/2010

Meanwhile, plenty of exchanges aren't even batching txs, spending blockchain space inefficiently... It's like every withdrawal request is input, the client's output and change back to the exchange for the next withdrawal from that address.

I'll try the homespun solution, install docker and all.

I'd be interested in your Internet bandwidth consumption, should you be wiling to share.

My (perhaps flawed) understanding is that in the current implementation, all nodes broadcast all channel state changes to all other nodes. This is necessary, of course, as nobody yet knows how to do decentralized permissionless anonymous path route discovery.

For those playing along at home, you'll no doubt note that (should my understanding be correct), BW consumption scales at O(n^2).

I'm sure it will improve when the routing invention breakthrough occurs.

On a tangentially-related matter, does anyone know why the forums got rid of the glowing ignore color, based on how many people have a particular user marked for ignore ?
Oooh.  I had never noticed this but would enjoy it.

Disappeared around the end of 2013, IIRC, about the same time avatars were locked (for years).  Avatars became changeable again within a couple years, but the forum just couldn't afford the expense of glowing ignore buttons.  There's the new software to develop, you know!  Can't be robbing from that for trivial things.

Pretty sure Bob was wanting to ignore me for all my various Monero shilling.  Maybe I could just change my avatar to a glowing ignore button?

I think the real news there is that a Norwegian company has 31,000 employees? Who knew.  Tongue

And they are wasting worktime when they daytrade.

Given the translation, I don't understand the scope. Is the company forbidding trading on the company's dime? On the company's time? Or any trading -- even private, off-hours -- on the part of employees?
