- I have a new SSD for my computer, so in this video, I want to move my operating system over to it and make it bootable. This will free up space on my older 1TB hard drive, but also give me more space to have more goodies. I'll have to do things like renew the device's copied UUID as well. I also move over my copy of the Monero blockchain to the new hard drive.

He leaked his partition UUIDs!
Instablaster...
You try to control it. But at the end "the Chad guzzle" slips out lol...4chad moment
A drive dedicated to CONSOOMING? Shame!
It looks like he's actually a big Disney consoomer ! Shame !
You just increased tenfold my disk management skill in Linux, in just few minutes;
After thousands of useless tutorial and scattered information for years... THANK YOU
Absolutely true and still to this day, good content about partitioning and dd in combination with tune2fs is pretty limited or rather non existent.
>not LVM over LUKS
You had one job, Luke.
luke, thanks for sharing your knowledge with us. I have learned a lot here on this side. you encouraged me a lot and provided me with a base to explore new lands.
universally unique identifier. the reason its "universal" is because its just a random number but its such a huge number of bits that the chance of collision is incredibly low and practically 0, even with all the devices on the planet that use it
I remember I had generated 2 same uuids and was freaking out, but turns out my drive was failing :P
ARE YA WINNING, SON?
I prefer labels over UUIDs since they are easier to remember and type in a tty. `mkfs.ext4 -L mylabel ` to add a label during formatting and `e2label mylabel` to non-destructively relabel a partition. Then replace UUID=xxxx with LABEL=mylabel and you're golden.
I'm so glad you pronounce fstab the proper way.
Came faster than notification alert. Lucky. Even though I probably won't understand it.
great video as always! :D
If you only need your locality's offline maps, the size isn't bad at all. I got all of Kentucky on my phone. If I recall, it was like 1.1GB. Cities are usually a couple hundred MB or so.
I coincidentally needed to do exactly this when you posted the video. Thanks!
I think this is your best video.
Luke, we already read the Gentoo handbook
22:45 Better use "which md" instead of "alias md" to display the current alias. Don't want to accidentally overwrite the alias by typing an extra character right before pressing enter...
$ type md
that would change change the alias for that current session, he could just reopen another terminal
This comment section is absolutely incredible
man chadpads are so nice
Thank god i got mine.

Edit.: Luke give us that GNU/Moonshine recipe.
Let's be conservative here
starts typing cp
really makes you think
>> ...hide some more... "sensitive" stuff on there... maybe my old... "emails"
Then pounds back so moonshine from his mason jar
thanks man
"we're always getting closer"
Nice subtle christian message.
Hi Luke, you mention Monero, but im confused the name of the folder is bitmonero (which is last developed in 2018) what actual client are you using?
Why not just change the UUID of /dev/sda1 to random, then you can omit all other config file and grub install stuff... Or am I wrong?
That sounds like a pretty nice shortcut.
You can omit changing fstab
But you have to reinstall grub
9:54 status=progress? Cool! I remember crude one-liners (or more) and using two terminals which looked more wrong the more I tinkered with bash scripting. Thanks. Also there is partclone you might want to check out.
You are not going to use LVM, just plain EXT4? I avoided LVM in the past und hoped that BTRFS, ZFS or some other more easy to use solution would arrive. Ubuntu decided to use ZFS, Fedora will give BTRFS another try, at work our RHEL servers mandate to use XFS (I was the one on the team to care to actually read their documentation), Stratis and VDO look interesting but for the mean time I got comfortable with LVM and it's not so terribly complex as it looks and you gain more flexibility. Running out of space, thinking about migrating to a bigger drive and many of the headaches of the past I could have avoided if I avoided LVM not that vehemently as I did. It seemed like legacy server-cargo-cult to me and you have your point not to make too much partitions which was also mine not too long ago until I ran this "Lynis" tool within the first weeks on my new job. :( Okay with LUKS and LVM caching it is crazy and I may have just gotten used to it.
i found ddrescue more convenient, it shows a nice progress and if you add log file, can continue if interrupted.
(UUID) is stands for "Universally Unique Identifier".
How could you extend your /home into sda1, Is there a simple way of merging both partitions when the data is in the second partition?
Luke pogging @ 4:34
how to delet porn partition from system 32!? y ur pc look like that and the slashes is leaning the wrong way tho!?
Luke, do you also realise how 99% of other Linux/Unix content on TH-cam are people who don't know how to do any of this kind of thing? Does it annoy you?
Can you use this method to copy your entire linux system (including swap partition) to a larger drive or is there a more efficient method for that?
Usr stands for "Universal system resources"
It used to stand for "user" tho. It's where the home directories of all the users were stored in. But they changed the meaning and use of it at some point to what you just said.
hey lukesmith whats your opinion on big chungus
Hi Luke, if you had changed the UUID of sda1 instead of sdc1 in minute 15:22, would it be possible to eliminate the next steps, since the UUID of sdc1 is matched?
That's right. I only did it this way in case there was some error later in installation so it'd be easier to undo it.
Hell directory, interesting

Mmm.. me too
Wow
what is the shortcut key you use to del UUID at 19:16 ?
is it df ???

I watched the video hoping to learn how to use fdisk on a drive with multiple partitions... Instead I was reminded how many extra steps you need to use with Grub and MBR
The partition doesn't think it's only 30.2 GB but reather the ext4 file system.
Dd...the disk destroyer
Destroyed my external hard drive backups countless times because I was too complacent and chose the wrong device drive
Could have needed that on Monday, before I screwed up my partition table and ended up with bad magic numbers
what if you wanted to change the letter from sdc to sda? would that be possible now?
What does the information in brackets mean?
This may be a dumb question, but when would someone want to use LVM over regular partitions?
You can make dd faster by using a buffer, like `dd if=... of=... status=progress bs=8MiB`
>directory named hell
must be where the anime goes
cool and educational, but wouldn't it be more efficient to just replicate /dev/sda on /dev/sdc using dd, fix the size & then just plug out the old drive?
I thought dd wasn’t recommend for solid state drives?
Does anyone know what happened? I just saw a notification for Lukes Channel "Last Livestream for now (rip)". I clicked on it but that livestream was already deleted?
2:48 how you edit/rename massive amount of files' names like that. I frequently ran across such edition and have to manually and one by one edit/rename them. Do you use globbing or sth?
that's just piping output to a pager. If you want to mass-edit filenames in a directory, use vidir.
@@LukeSmithxyz thank you!
I use "nnn" for that. Pressing R takes you to vim where very line I the name of a file in a directory
From there you can use macros in vim/nvim/gvim
@@joselaw6669awesome. thank you.
What is the purpose of having copies of the blockchains?

What is the best way to backup your data in linux to either a new drive, or flash drive, etc? If I tried to boot from this drive, would it boot?
Never mind, I watched on and saw how you boot from this new partition.
24:30 now drink from that pickle jar
When I tried this on my system everything copied over just fine and I was able to reinstall grub and generate grub.cfg. But for whatever reason grub would not recognize my linux install on boot and just kicked me into BIOS. Not sure why. I was able to fix it by reinstalling linux via Artix wiki on top of my existing install and then generating a new grub.cfg. Glad I didn't have to reinstall from scratch. Now I've got 2TB of storage on this bad boy.
Drinking some liquid from a jar was the most boomer thing I've seen in a while 😅
So we're just ignoring the BLACKBOARD behind him?

@Its GNU /Freedom GNU/Thanks for correcting me 😎
Hunter Bidens laptop uses LVM partitions
Good one
Lukes btrfs please.
Btrfs master race!
Thanks, I hate Tux with Pepe the frog's head.
Luke, why don't you use LVM instead of regular partitions?

Wouldn't dd run faster if you specified a bigger block size? Last time I used it the default was pretty small. In fact you can see from the number of records copied that each one is 512 bytes. This link
stackoverflow.com/questions/6161823/dd-how-to-calculate-optimal-blocksize
Suggests bs=8388608 (some versions of dd allow 8m or 8M as a shortcut) is a good starting point. The idea being that you spend a bit of time setting up a transfer and by making the transfers bigger you amortize that.
Look up history etc is actually ECteta that is why so many things go there and yes usr is user linux was created kiss
If we have a boot partition on our system will we need to make two partitions on the new hard drive for the root and boot?
Nvm I put my big boy pants on and figured it out
@@thatdude8020 tell me how daddy
Post garden folder
Dont need to partition the drive if you don't put OS, just "mkfs.ext4 /dev/sdX" the whole drive.
nice! thanks for the tip.
So, why does one need to use chroot when they could instead just do:
nvim /mnt/etc/fstab
pretty sure chroot changes the behavior of grub install.
usr = unix system resources, but everyone including Brian Kernighan calls it "user".

Should I just change the old partition uuid and have everything set up?
- No, I'd rather change the new partition's uuid and change all the settings.
65MBps is 520Mbps. Definitely nowhere near the cap of 3Gbps which is about 375 MBps on SATA II.

But not everyone uses grub, some people just like simplicity. They use systemd.
And some people like even more simplicity. They use Windows 10.
@@BurgerKingHarkinian you're hurt because systemd boot is less lines than grub.
@@Aemilindore Ah yes, I'm in indescribable pain rn because of that.
Also let's just forget about the monolithic, Unix philosophy violating nature of systemd. Systemd is a flawless "init system" without any flaws.
Those who dare criticizing it are just butt-hurt. lol
@@BurgerKingHarkinian sure, if you don't use systemd in your os instead of unit, it makes sense to use init. But if you use systemd, then systems boot it is.
@@Aemilindore Idk, never really given much thought to systemd's boot manager. But yeah, if you're already using systemd, I can see that you may just want to use that thing as well. Never really compared it to grub or anything.
It's just funny to me to use the words "simplicity" and "systemd" in the same sentence.
3 hard drives is bloat, i use a single usb stick
/usr = unix system resources
PayPal announced they will begin to deal with Bitcoin.
Finally, some good fucking Linux
Clean your keyboard bucko!
i would avoid pronouncing /usr/ as "user" because it is NOT supposed to be related to "users". it's meant to stand for "universal system resources" so i say "U-S-R"
That's actually a backronym. /usr/ was originally meant for user home directories and has always been pronounced "user". /etc/ was also originally pronounced etcetera, despite similar backronyms being created for it. Brian Kernigan (who helped develop UNIX along with Dennis Ritche and Ken Thompson), directly refers to /etc/ as "et cetera" and /usr as the "user file system" in his book The UNIX Programming Environment. Speed when speaking ("go to et see resolve dot conf" vs "go to et cetera resolve dot conf") is the only reason to not say et cetera when referring to the folder, as it is technically more correct to do so.

Hey Lukesmith what’s your opinion on Big Chungus
slow down
More on crypto - blockchain pls
uh, again this useless linux stuff
you gotta stop with your poly-amorous hard-drive degeneracy. 1 hard-drive is optimal, more than that and they start getting envious of each other. they forget how to read and write, and then they just refuse to work. always leads to disaster.
Meh, I am not entertained!
fs-tab? Nah. It’ll always be f-stab to me.
