Actually after a lot of testing, the issue are actually the controllers LSI 9211-8i that are not working well in my hp system under Ubuntu, in Windows they work, that´s the odd part. I have bought a Dell H200 a couple of days ago and I´m getting exactly the same issue, I really don´t know what controller o buy, I´m throwing a lot of money on useless stuff.
Both HP SAS expanders are working now with my internal P440ar but it is not capable of "daisy connection" between expanders, so I really need to get some other SAS controller working asap.
I belive there has to be some driver problem between LSI 9211-8i and Ubunut, I really don´t know what to think or do.

Hope you can help me, thanks in advance!

Yes, I think the expanders are the one creating my issues because on windows some times it takes long to recognize the disks after restarting.
I've been many days trying to find a firmware update for the expanders and how to upgrade them but no luck, perhaps this would fix my issues.
I'm only connecting these disks this way, I found a better and cleaner solution using 24 bay backplanes from supermicro that should work much better.
Do you know of any link for the firmware and some explain on how to install?
Yes, I´m really sad for not being able to use Ubuntu, I actually blame Windows for my times, not Madmax. Before this I kind of avoided Linux at all cost in my whole life, but with Chia I started to learn, and I even started to like it a lot.

My main fear is that with only 36 disks connected its giving me a lot of issues with the drives, I tried everything, flashed my LSI 9211 - 8i to IT mode with P20 firmware, tried different methods for formatting with Parted, gParted, fdisk, all of that and nothing, I cannot imagine what things will I encounter when I connect all of my 120+ drives, my concern is finding out halfway plotting that there is no way to connect lets say 40 percent of the drives since I want to buy connectivity hardware while I finish plotting the ones connected.

I really appreciate if you can shed some light on my controller issues. For background, I have the controller connected with two HPE - 487738-001 SAS expanders cards. I  actually keep Ubuntu in another SSD to dual boot.

Thank you so much again, If you´d like to connect in a more direct way through Discord or something please just let me know.

Kind regards!
Thanks for replying.

I´ve been testing in Ubuntu and I managed to get 2 plots in 47 minutes dual plotting or one plot in 29 minutes single plotting, but my issue was that I spent almost 10 days trying to fix an issue with my final mechanical SAS disks. Ubuntu for some reason wont accept them, not even let me format them or do anything to it claiming an input and output error.
Because of this I ended up switching to Windows and no loosing any more time. I really would want to get both windows instances times the same, because windows time with one plot is near 50 minutes.

My processor is 2x E5-2650 v3 running in a DL380 G9 server with 256 of RAM. I think MadMax is underperforming a lot for me.

Could you please give me some advice on what could I do to get the same time in both instances?

Hey there,

I´m plotting in a Server with 256GB of ram 2x10c 20t processors, with two ramdisks and two NVMEs. I open two instances of Madmax and assign one processor to each one in the task manager.

The instance with processor 1 does the job in 59 minutes but the processor 0 does it in 69-75 minutes, it is a huge difference considering it is exactly the same hardware for both, even the NVMEs are the same.

I have tested some time in Ubuntu and both instances were done in 47 minutes (no difference) but I had to switch to Windows because I was having final disks incompatibilities issues, so this meanse that in terms of hardware everything should be the same time.

One doubt I have is when creating two ramdisks there is no way to saparate nodes, I mean, one ramdisk created with ram in node0 and the other ramdisk created with ram in node1.

Does anyone have any idea on how to solve my main problem?

Thanks in advance.
