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 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.
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.
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.
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?
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.
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?
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?
Luke, do you also realise how 99% of other Linux/Unix content on UA-cam are people who don't know how to do any of this kind of thing? Does it annoy you?
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
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.
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?
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.
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...
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.
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.
@@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.
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.

I remember I had generated 2 same uuids and was freaking out, but turns out my drive was failing :P

I'm so glad you pronounce fstab the proper way.

Luke, we already read the Gentoo handbook
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.
man chadpads are so nice
Thank god i got mine.
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

Edit.: Luke give us that GNU/Moonshine recipe.
This comment section is absolutely incredible
(UUID) is stands for "Universally Unique Identifier".

Nice subtle christian message.
I coincidentally needed to do exactly this when you posted the video. Thanks!
great video as always! :D

Dd...the disk destroyer
Destroyed my external hard drive backups countless times because I was too complacent and chose the wrong device drive
i found ddrescue more convenient, it shows a nice progress and if you add log file, can continue if interrupted.

This may be a dumb question, but when would someone want to use LVM over regular partitions?
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?

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.

$ type md
that would change change the alias for that current session, he could just reopen another terminal
What does the information in brackets mean?
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.
What is the purpose of having copies of the blockchains?
what if you wanted to change the letter from sdc to sda? would that be possible now?
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.

pretty sure chroot changes the behavior of grub install.
