Absolutely true and still to this day, good content about partitioning and dd in combination with tune2fs is pretty limited or rather non existent.

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

You try to control it. But at the end "the Chad guzzle" slips out lol...4chad moment

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.

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?

i found ddrescue more convenient, it shows a nice progress and if you add log file, can continue if interrupted.

You can make dd faster by using a buffer, like `dd if=... of=... status=progress bs=8MiB`

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?

Luke, do you also realise how 99% of other Linux/Unix content on KZread 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?

hey lukesmith whats your opinion on big chungus

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.

Wow

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

Could have needed that on Monday, before I screwed up my partition table and ended up with bad magic numbers

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?

What does the information in brackets mean?

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.

I thought dd wasn’t recommend for solid state drives?

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.

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.

@bullfrog9296

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.
