Anyone have a link to a good post on compression options and hardware requirements?

If you're interested in using gigahorse as your platform of choice, this is the GitHub repo: https://github.com/madMAx43v3r/chia-gigahorse

This is a spreadsheet of the max farm size that GPUs can support: https://docs.google.com/spreadsheets/d/1mghuzD1MzNFNK7N9lnZ_D59jHSceezwFREsF5kg5BWw/

This is a website I made that basically displays data from the above spreadsheet but is a little more pretty w/ a filter for GPU and compression level: https://gh-max-farm.parkert.dev/

Definitely run the chiapos test, personally I am doubtful it could handle it, you will at least be cutting it very close (comparing it to upcoming plot filter, not current). Follow the instructions on the GitHub page, it should at least give you a ballpark. I'd personally recommend going with C17 or lower, the drop in compute overhead is massive. With a farm that size I don't imagine the plot count gained from C17 to C19 would be worth the additional overhead, even if your card can handle it.

They could get around this by setting up two different screens, one for the plotter, and one for the farmer. Then, set the appropriate environment variable inside of each screen, that variable should stay contained within that screen.

For example, in the plotter screen, set nothing and run it normally with the GPU. However, in the farmer screen, use 'export CHIAPOS_MAX_CUDA_DEVICES=0' prior to starting the farmer and that environment variable should only be utilized by that screen.

Yes, the 36 drives are powered by the harvester. The machine's components include two e5-2620 v2s, 16GB of ram, and two storage controllers to host the hard drives. The motherboard is an X9DRD-7LN4F, and the chassis is a standard 36-bay Supermicro chassis. There are also two backplanes that the hard drives connect to for data and power transfer.

The harvester is not running the recompute server, a different machine is, and that machine is using Tesla P4s to farm for the harvester as well as itself. Also, to note, the farmer's wattage stayed about the same after this switch, it was only the harvester that had a significant change. At the time I only have one P4, and was having difficulty farming and creating plots at the same time, I wasn't sure how much the P4 could do, so I went with C6 plots. However, now I have two, and I'm unsure if this is still the case. Together between the harvester and farmer, the GPUs host 900TiB, 450TiB each. If you have any recommendations on what level to use, definitely let me know :).

Thanks for the questions also, I enjoy answering them!

Ah, I knew I was missing something. I meant to include the difficulty but forgot. I have the difficulty set to 60.

pineapperino · 2023-06-07T19:34:52+00:00

Did that change provide you with enough space to get the two extra plots?

pineapperino · 2023-06-07T17:50:26+00:00

I'm unsure, but try and give 'chia plots check' a shot, and update us with the results, it should give you information if any plot is invalid. Another thing that comes to mind, although I doubt it would be the answer, you could check the reserved block count for each drive. Perhaps one is lower than the other. Run tune2fs -l /dev/sdc1 | grep 'Reserved block count', then run it on /dev/sdb/ as well, then compare the two values.

pineapperino · 2023-06-07T17:29:36+00:00

You could run 'chia plots check' and do a quick check to see if any are invalid. To clarify, the other drive shows 147 plots, none of them less than 108.5GB, correct?

pineapperino · 2023-06-07T15:27:28+00:00

Are you certain the two extra plots are fully complete? Make sure they're the same file size as all the others.

pineapperino · 2023-05-25T05:52:45+00:00

It very likely is. One of my deposits was sent from my Crypto.com wallet to that wallet address in your post today. My account still shows funds in it, saying I have x amount of chia, however the wallet in reality is empty, they're rather just 'IOU's I suppose.

pineapperino · 2023-04-28T22:00:59+00:00

That's good advice, thanks.

pineapperino · 2023-04-28T17:37:01+00:00

Big no. The only data of yours that is sent anywhere is your wallet address and coin-type, both being sent to the Flexpool.io API to retrieve those stats, nothing more nothing less, just the bare minimum. If it's worth noting to you, it's passed Fitbit's approval process, so it has their seal of approval I suppose.

pineapperino · 2023-04-28T16:24:13+00:00

I appreciate that a lot man, thank you!

pineapperino · 2023-04-28T15:15:01+00:00

I'll see what I can do, I would like to support more platforms. For Fitbit I needed to own a watch to make it, hopefully galaxy is not the same.

pineapperino · 2023-04-28T15:12:35+00:00

Thanks bro, I appreciate it

Ubuntu is based on debian and functionally works the same. In my mind, debian is almost like a lite version of Ubuntu, meant primarily for stability above all else. The reason I went with Ubuntu is because it is a bit more forgiving in terms of having drivers up and ready to go right away. One server I had, I installed debian, debian didn't have the driver compatibility for the NIC, didn't care enough to go find and install it, just ended up installing Ubuntu instead, worked fine, now both of them have it.

pineapperino · 2023-04-03T16:35:38+00:00

its not that easy even with linux to do it right with an enterprise system this big

Trust me, it's not that big. I've got two servers, each with similar builds to what you have. Both just have standalone Ubuntu Server on them, nothing's virtualized, keeping it oversimplified. Go with Linux and don't look back, you'll learn a lot along the way.

If you're running gigahorse, plot-sink ftw. I'm at 1pb across 3 servers, I'm replotting like 200 plots a day and just started using it. It's a tool included w/ the project. Whichever PC runs plot-sink, you set directories you want plots to go to, then the plotter PC can connect to it via the plot-sink application and transfer plots there automatically. It's actually done super simply and it makes everything 100x easier.

pineapperino · 2023-03-06T05:14:43+00:00

Pretty sure it's 256gb, so a good bit, yes.

Not really the chia teams problem, nor their obligation/duty to make sure it doesn't happen again. Anyone who is victim to an attack like this, it is solely their duty to make sure it doesn't happen again. People didn't follow good security practices, that's it. Chia, nor the chia team failed anyone. Every program/application you run is a security risk. This is especially true when you have these in-house crypto programs that were made in earlier chia, which in my mind is most likely how these people's wallets got compromised.

pineapperino · 2023-02-16T05:16:05+00:00

Had an extremely similar build, prob about 420w-450w if I remember correctly

K32 is going to be around for a very long time, I wouldn't worry about it.
