To expand on this some if you're more of a visual person:

If you open the keyboard application, (just called "keyboard" when you do a search in your applications.) the second tab is "Shortcuts". From there you can see an interface that shows and helps you change all the shortcuts on the system.

You can use the search feature to narrow things down quickly. The multiple "screenshot" shortcuts were nice to find for some common use cases I do.

That's what I was wondering as well?

If so, what's the "correct" location to store stuff like documents, downloads, configurations, etc.?

FYI, if you go to "Account Settings" and uncheck "Show Read Posts", this should automatically hide all posts that you open, up vote, or down vote.

I understand and agree though that having the ability to split that into separate options would be nice. But this might help you until they possibly add that option later. This is also tied to your account and not just the app, which is nice if you use Lemmy from multiple devices.

Currently though, I and several others are having issues where the last update appears to have broken that feature. I'm not sure if the issue is instance specific, (lemm.ee) or more broad.

I'm having this issue as well. Let me know if you find a solution.

Anyone know what pest may have done this to my retaining wall? in c/asklemmy@lemmy.ml

This is exactly what it looks like.

I had this exact situation happen to the fascia boards on my previous house. Carpenter bees bored into the wood and were living in it. Then a woodpecker came along and got them.

The damage in your picture looks exactly how my fascia boards looked after the woodpecker got his meal. You can also see the tunnels that go into the wood. I never even knew the bees were in the fascia, but somehow the woodpecker did...

Help Request - Proxmox Partitions/Boot - CloverBootLoader (lemm.ee)
 

Sorry for the wall of text... This ended up a lot longer than I thought it would...

TL:DR - Looking for guide to partitioning/booting and/or help with Clover config.

Background

I recently purchased a used Dell PowerEdge R730xd to use as a home lab/self-hosting project. The intention being I would install Proxmox and play around with it and see what I wanted to add in to it later. As the server did not include any drives, I figured I would purchase a PCIe to NVMe adapter to work as the "boot" drives for the system and then fill up the 24 drive bays over time if I decided I wanted to continue with the setup.

I purchased one of the Asus Hyper M.2 x16 PCIe NVMe cards that supports up to 4 drives. To go along with it, I purchased 2x 1TB Samsung 980 Pros. I had done some research ahead of time knowing this might cause some issues, but it appeared that they could be worked through.

Installation

I installed the drives and card and turned on PCIe bifurcation for the slot. The server/iDRAC didn't see the devices, but this was expected based on prior research.

Using Dell's iDRAC, I was able to virtually attach the Proxmox .iso and boot into the installer just fine. For my Proxmox install, I chose to use "zfs (RAID1)" with both 980's as the drives. Installation appeared to go through without a problem and I rebooted to finalize the install.

At this point, the server does not recognize a boot option and hangs in the POST menu asking what to do.

Problem and Possible Solution

I was aware this might be an issue. From what I've gathered, the server won't boot because of them being NVMe in the PCIe slots. Plus the fact that they don't even appear in iDRAC or BIOs confirms this.

I had discovered this is a common issue and that people suggest using Clover as a way to "jump start" the boot process.

I found this guide where someone appears to have gone through a very similar process (although for VMware ESXi) that seemed to have enough clues to what I'd need to do.

I installed Clover to a flash drive and did the steps to move in the nvme drivers, booted into Clover, and created the "preboot.log" file. I then started to edit/create the config.plist file as they described in the guide. This is the stage where I ran into problems...

Troubleshooting and Where I Need Help

When I opened the preboot.log file and did the search for "nvme", I found multiple listings. (Copy of the preboot section below for reference.) This is where my understanding of things starts to run out and I need help.

There are 8x volumes with NVMe being referenced. (The USB listings I assume are from the Clover boot media.) Just looking at the numbers, I think this means there are 4 partitions per physical drive? I assume that the RAID1 install means things are duplicated between the 2 drives.

I did some more research and found this guide on the Proxmox forums. They mention starting into the Proxmox installer and doing a debug install to run fdisk and blkid to get the PARTUUID. The second post mentions a situation that sounded exactly like mine and provided a config file with some additional options.

I got into the debug menu and ran fdisk and blkid (results copied below). This again is where I struggle to understand what I am seeing because of my lack of understanding of file-structures/partitioning/boot records.

The Request(s)

What I was hoping to find out from this post was a few things.

  1. Can someone explain the different pieces of information from the fdisk and blkid commands and preboot.log? I've done some work with fixing my other Linux server in the past and remember seeing some of this, but I never fully "learned" what I was seeing. If someone has a link that explains the columns, labels, under-lying concepts, etc, that'd be great! I wasn't able to find one and I think it's because I don't know enough to even form a good query...
  2. Hopefully someone out there has experienced this problem and can look at what I've got and tell me what I've done wrong. I feel like I am close, but just missing/not understanding something. I fully assume I've either used the incorrect volume keys for my config, or something else in the config file. I'm leaning on the former, hence point 1.
  3. If anyone has a "better" way to get Proxmox to boot with my current hardware, I'd like to hear it. My plan was to get Clover working and install that on the vFlash card in the server and just have that jump start the boot on a reboot.
  4. Hopefully this can serve as a guide/help someone else out there.

Let me know if you need more information. I am posting this kind of late so I might not get back to your question(s) until tomorrow.

Thank you for posting this with the explanations and great visuals! I am wanting to upgrade to a setup almost identical to this and you've basically given me the bill of materials and task list.

Anything you wish you had done differently or suggest changing/upgrading before I think about putting something similar together?

Any way you could update/create your own drawing with what you mean? (Bad paint drawings are acceptable!)

I ask because I am curious if I am subject to the same problem. I'm not the most networking savvy so I need the extra help/explanation and maybe the drawing will help others.

I'll throw my code into the ring as well. I posted it over in the Python community and have been using it myself.

It's not the most user friendly yet though. Still working on improving it as I get time though and open to suggestions/requests.

Sorry for the delay in getting back.

Currently it will not work with 2FA enabled. However, looking at the login post requirements I just need to add that as an option to put in the config.

I'll reply to this comment again when I get something put together. I'll add it to the GitHub issues list for tracking as well.

However, could you recommend an instance that uses 2FA for login so I can make an account to test it? I see the field in my current instances but would like something fresh to try it on.

Someone already posted the wescode migrate, but here's my Python code that does a bit more. It's not the most user friendly yet, but I'm working on it.

Correct. lemmy.world was my original account. But with the server strain going on, I've hopped over to lemm.ee and also have a couple other accounts. Just run this script every so often and all your accounts will more or less feel like the same account.

[–] Ac5000@lemm.ee 1 points 1 year ago* (last edited 1 year ago)

Yeah, for anyone that gets the 502 gateway error. That means the instance was down when it tried to login/didn't respond. I'm going to revisit this part of the code later and see if I can fix/handle that happening so it at least goes through with the rest of the accounts. If it happens to you, just run it again and hopefully you'll get through at least once.

Subsequent runs actually hit the servers with less requests since you can pull most of the info you need with the initial site response and I check that before making any needed requests.

Also, someone else mentioned they had a problem with the none type thing. I'm using Python 3.11 and forgot to specify that. I'll add it to the readme when I get a chance.
