We need a Level1Rants channel so Wendell can finally get it all out.

"The reason Apple's a 3 trillion-dollar company is not because their hardware is amazing. It's because their software is cohesive" Totally agree. I wish more FOSS developers would focus on usability over adding new features. I don't mind running home assistant (and occasionally tearing my hair out) for _my_ smart home but I would absolutely choose something like HomeKit for my parents home since it's so much easier to configure.

Wow, this had a real pre-Tek Syndicate blowup feel. Well, except we see Wendell's face. Thanks Wendell. Good times... again.

This is really incredible! I've always had the same hatred towards managing a lot of SD cards scattered around the house but I lacked the knowledge about netboot and was kind of overwhelmed by all the information online when I first tried it. Thank you for these lovely rants!

the Mountain Dew can and unenthusiastic facial expressions make me feel at home. Thank you for everything you've taught me over the years Wendel.

I got a large amount of old rPis recently and this is exactly what I needed. Thanks for the video!

This is why teaching STEM is so important ESPECIALLY the open source side. Open source depends on community and the more young people we educate in this field, the better off humanity will be.

Whenever I start a new project, I just need to wait about a week and Wendell will show me everything I'm doing wrong lol PS, still waiting on that Openshift walkthrough

Dude !!!!!!!!!!!!!!!!! I just found this channel looking for 100G network cards. Saw a bunch of really simplified and accessible concept explained in that video and clicked on this one. That's it I am subscribing. I've spent too much time around large scaled data centers that I no longer know how to even make up cheap and easy solutions. Now that I bought a house and get the grind to bring a bunch of home automation, I am finding out how insanely expensive it is to have automated HVAC or humidity tuned.

Amazing! Have been looking for the info for some time.

When I see a video with Wendell. "My body is ready"

I have that same O11 case. I really love it.

Amazing!!! In this internet world thar 90% of tutorials and ideas is a just copy and paste from other guy, i found your new, fresh and cool content! thanks for sharing

I'd love to see a video going over the setup of a server for this, and other computers.

This is great! (restarting for better comprehension)

I was worried you were about to say Apple's software was amazing. 'Uhhh, very cohesive' is a perfect description.

Thanks!

I'd buy a recipe themed book with Wendell and Jeff Geelings face on it. Kinda like the CCNA command booklet.

great video... looking forward to some ansible examples

Great tutorial sir

You have no idea how timely this was. My main rig has a weird hardware error (windows works unless I run Prime95, linux throws hardware-error/kernel-panic at boot) so I was looking towards setting up a RPi4 on remote boot off my TrueNAS to carry me over while the machine is in repair. Most internet guides are crap, not telling you why you do what you do. Thanks!

In a Palpatine voice when talking to pfSense: “Initiate option 66”!

Lol, just came from the main channel. We need an "I'm feeling lucky!" button right that takes us straight to this video from the main channel video intro

Danke!

Exactly the thing that i am currently working on. But instead of copying all of the root fs for each rpi my plan is to have a single read only one and on top of that mount a rw overlay fs for each rpi. That way i dont have to do updates to base system of each rpi and it becomes even more easier to manage.

This is nice. I gonna trying with my openmediavault setup. 🤔👍

They say that when an idea needs to exist many people are thinking about it. I’m working on netbooting my pis that are part of a Kubernetes cluster as well. I found someone selling a tutorial (that’s new) and many fragmented tutorials to get it working. Was going to write up my own and here we are. Might still do mine. The world can always use more info.

my man, great video. Have you thought about collabing that ansible video with jeff geerling? Guy loves his pies and wrote a hell of a good book on ansible

Cool idea that many have already done. However for people who are familiar with the components and not this exact scenario. The "Write Up" lacks many details which is required for this to work. Expect to spend more time watching other videos piecing together the missing bits.

very nice!

Raspberry Pi OS 64-bit is official! Awesome, now we can make even overpowered setups

this is super cool

Great one! But honestly I'd go for iscsi boot if possible, it's just faster and more reliable. And yes if you have the rootfs on a CoW filesystem like btrfs, zfs and even xfs, you can just copy the folder with cp --reflink=always and benefit from "deduplication". Reflinks are the new hardlinks that point to the same data on disk, but with the twist that the files can be modified individually.

17:29 For me the deal breaker was when he said NFS is slower than booting from the SD card. I mean, it is great for centralized management but penalizing speed on a device that small is a no go. Also having a NFS folder there accessible for hackers to audit is a consideration if you were planning on deploying a ton of Pi to strangers.

Nice video. I am moving from a power hungry server to raspberry pi to save costs. So, the x86 server is put to sleep during night. Thus i dont have any NFS server running. My solution was to use a usb ssd with the pi with ZFS. I am able to snapshot the dataset and send to the server. So, the server always has a good copy.

ostree looks like it would work really well with this

this is why i patreon

Can’t wait to go home and try to figure this out. Only down side is my nas is on the same box as my main pi hole and my ras pi is backup dns, so if one box goes down it takes out my other. I just need more hardware!

At 11:00 I think there was a misspeak. The tftpboot folder contains the serial number. The pxe folder should be the config where you can name the file whatever. I believe, anyway. The tftpboot folder was mentioned twice for the two different types of files.

woohoo! Level1linux videos!

Love to see a video of you doing something with something like pixiecore or maas.

Now you only need to get the NFS file secured. And you also might want to use something like ubuntu server, because Raspbian has a lot of weird quirks, like not having a separate repo for security updates, that burn you if you want to do a proper setup.

They now have a supported / released 64 bit img file from raspberry pi. This could be nice for more IoT device processing

Thank you for the article. On a side note, you sound like neil degrasse tyson.

sonos is simply superior. moodeos + decent pi dac + low noise power supply + bookshelf speakers can get better audio but sonos has room correction + better streaming and can also do stereo all while looking clean and elegant. Besides pi's have always had a supply chain problem akin to GPU's so my 3B+ is sitting at the office with usb dac + power amplifier + two speakers until i decide there is a worthy portable usecase.

Would love to tinker with this stuff, too bad you can't buy a raspberry pi at the moment :(

Raspberry Pi 4's are capable of booting via HTTP. It uses this to boot the Pi Imager (set BOOT_ORDER to 0xf71). What would be nice is to HTTP boot a mini boot image that then would mount your nfs mountpoint. This would avoid any dhcp/tftp mucking about. I just can't figure out how to create that initial kernel image. Hmph. Stil WIP.

how do you feel about that CO2 logger? Was looking to buy one

Looking forward to working on this project. Today I run 5 pi4s with Ubuntu 20.0lts running a service on each pi, services include asterisk, 2xpiholes, homebridge and home assistant. I run a number of vlans and dhcp is handled by my draytek device. I already advertise option 66 for booting my Cisco 7962 phones. At the moment all the pis backup via nfs to a Synology nas. Network booting sounds like the ideal, centralise the file systems and push out the processing. I am wondering if I have my warm standby pis if I could dhcp assign each pi to a pool of addresses that can access the nfs area, then boot using a configured static IP address set in the root for each system, that way if I pi failed I would only need to rename the boot folder to the serial # of the replacement pi. And not have to mess about changing the dhcp config so the new pis MAC address linked to the old pis IP address. I will have to see if the boot progresses will stand having his IP address change mid PXE boot.

The question I would have is can you get a tos link or hdmi for higher sound quality output

An SD card is faster than NFS? When did that happen?

Wendell is my Spirit Animal.

I wonder... if we had many Pi and most of them were running the same OS, I wonder if it would be worth setting up dedup as many pis could take up a lot of space. also oddity my network boot screen (without SD card) looks like the raspi imager ... says its trying to boot from the network. .... and, we have lift off (forgot to start the TFTP service in truenas scale)

Absolutely based on Copyleft too 😍

Could you guys potentially create a walk through using unraid? I'm having some issues trying to get it to work. I'm using a CIFS share because I had issues with NFS from unraid, but I think I will try again with nfs

i really got to try something like this but I'm just tired from work

Any advice for an off-grid, off-network standalone system? Star-link is still a ways away for my rural area...

Wendell... in your forum post, you skipped over the step on how to enable tftp server on truenas.... unless that's automatic? Is there any configuration necessary? Thanks fort this.. very cool stuff

Noiiiiice

hi you can also find the Pi serial number with cat /proc/cpuinfo | grep Serial | sed 's/.*: //' but it's padded with zeros to a length of 16.

How do you protect the filesystem from something else on your network sniffing out these images?

thx for this wendell you a wizard , how fast is the IO overhead or network overhead on nfs compared to samsung 3.0 ssd usb stick with the usb bootloader hack

"I assume if you're doing this with raw linux, you know what you're doing" Well, I actually came here to learn more about it; and through trial and error, figure out what crosses over. Anything I lookup just yields results for PXE installation of linux, but not how to have a remote boot image that loads into, say, a ram-disk. I'm not a linux noob, but more familiar with windows on the IT side. Any suggestions?

Would love to see this tutorial with iscsi instead of nfs

Note that if you want to run Kubernetes on your raspberry pi's you have to configure iSCSI instead of NFS for the mount Kubernetes works in, and it needs to be mounted before docker service is started. Kubernetes gets butthurt if its work mount isn't a block device.

So there's an initial boot image loaded that requires router configuration? Can the SD card be used for that part? Or a USB stick on a PC. Probably a good bit of figuring out to get that setup, but... If my server can boot from a UEFI imagine on a USB stick, I imagine it could have a script on it too. Likely the same for any device that has USB flash back/BIOS recovery mode. Probably device specific to the put of being outside a one-size-fits-all tutorial though.

Ok, ok. I love the idea of network boting the rPi. Pi's often are thrown in a dark corner, without much oversight. This makes the entire setup super flexible, as you can easily create backups, try every Linux distro under the sun, and you also get "some" security benefits. But keep in mind, you can probably flash the u-boot bootloader of the rPi from a sophisticated enough attack.

@10:50 I call my pool Dozer just to be different....

Holy hell, it's so nice to be a nerd. _engagement_

Pixie Boot and Citrix provisioning services does this.

>The reason Apple's a 3 trillion-dollar company is not because their hardware is amazing. It's because their software is... uh... Good god that made my day. 😭 Thanks Wendell

I had better luck with iScsi root on my nas. With symbology nfs the system will boot but complain some file permission is not correct and cannot reboot.

Just when 64bit goes live. How'd he know!

I miss teksyndicate so much with all 4 of you guys. You Pistol Logan and Quan. It's never been the same. Both channels aren't half as good as the original.

I'm interested in what the CO2 level monitor is. Anyone has any idea?

Nice! More Linux please.

Something I've been wondering for a while is if there's some sort of happy medium between the image being completely on the SD card and netbooting. I'd love to remotely manage and deploy images onto a RPi (or other SBC), but not have the device go down if the router happens to go down. Though, I guess since the example used PoE, it's kinda moot, but I digress. Wireless image updates for SBCs. Saves network bandwidth, uses local compute where possible, and remotely/centrally managable/deployable. Kinda like firmware updates within the LAN, but for Linux devices.

One question: will the Raspberry Pi stop working if the boot server restarts?

My mind has been blown: I always said f-stab, never even considered FS Tab.

Does Netboot require ethernet, or Wi-Fi can do it too?

The audio jack on the raspberry pi is unusable, it has horrible current noise, it’s very audible, I’ve tried that eventually I connected JBL Pebbles because it come with USB DAC.

This is very useful information, but I'm a bit concerned about the EEPROM if one is to be truly worried about persistently compromised hardware. Is setting eeprom_write_protect enough?

Is this similar to Serverless architecture?

This is the final boss of Linux.

you should put your autopilot into hooman mode :)

You can not get to further a due if you like. 😊

Too bad it’s not possible to have an encrypted / secure connection.. afaik it’s just straight up dump UDP with our ssl/tls

Repeal the DMCA!!!!

6:05 (30% of the way into this video, quote: "first step is...." Sheesh, i understand the need for income, but that's a lot of overhead!

Great! I’m super excited to try this! Oh wait. All my pi’s are connected over wifi.

Execute option 66

It is to tiny to watch,zoom on interface

The only sad thing about this tut is that you can’t get a rpi4

Too bad raspberry pi 3b+ is like 125 dollars rn

I can write bash scripts!

You should do a colab with Jeff Geerling for the Ansible video :-)

The first six minutes of this video can be skipped.

Jesus.... Almost 9 minutes had passed when he almost started to do it. 😂 Even he says: "But this is not the purpose of this video" like 3 times. Focus dude. FFS.

Too much steps... It is easier to get sd-card, insert it into sd-card reader and clone prepared partition into it, then plug it back and turn it ON. That's it...
