Linux Storage: Avoid These Common Mistakes When Working on Partitions

[@DV-ml4fm]

I use LVM. You can expand or decrease on the spot. Plus do snapshots of your lvm.

really needed video. when installing arch i forgot to create a swap partition. this video will help a lot!

[@SavvyNik]

Glad it helped remind

Excellent video, straight to the point! I managed to increase my Debian VM partition size successfully! One thing I'll add, though: once increased, I noticed that the VM took way longer to boot than before the increase. I noticed the error "Gave up waiting for suspend/resume device" during boot. Also, the free command said that swap size was 0. So something wasn't right. Turns out that because I removed and replaced the swap partition, its UUID had changed, and the OS was looking for the old UUID. I had to do the following: 1. As root, run blkid to get the new UUID of the swap partition 2. Change the UUID of swap in /etc/fstab 3. Change the UUID in /etc/initramfs-tools/conf.d/resume 4. Run update-initramfs -u 5. Reboot. Hoping it helps someone down the line!

Verry nice. Just to say that gparted allows you to move swap partition once is off. No need to delete it and remake i. Just switch it off and move it at the end of unallocated space

Now, I have a lmde in LVM on half of my disk and want to install ubuntu into the remaining part. Why does that installer warn me it will overwrite LVM and swap, when only the partition for ubuntu is ticked, format set up for exr4 journalling system and root defined by /? Even colours ditinguish the partitione for ubuntu separately from everything else, in the installer as well as in gparted. I cannot get my head around it. I just installed lmde mint cinnamon, resized it, created another partition for ubuntu and ubuntu wants to overwrite other parts too? I don't get it.

Thank you. This helped me avoid some big errors. 😀

I've tried using gparted in Pop!_OS to change a partition that was created on install of Ubuntu 23.04 that it could not write the changes. I had to boot into a live Ubuntu 23.04 to change any partitions on 23.04. I think I remember it saying something about the GPT tables.

[@SavvyNik]

Thanks! Yes, most distros will require you to boot into a live image to make changes to the partitions / storage.

[@unklebonehead]

@@SavvyNik I meant it wouldnt do it from a Pop!_OS live image. I had to go burn a new Ubuntu 23.04. Even an Ubuntu 22.04 wouldnt do it. Something is changed on gparted between 22.04 and 23.04.

[@SavvyNik]

Well I can't say I've ran into that issue before.

How to deal with encrypted partitions since gpartes sees it as occupying the whole partition

[@AgentTex13]

My Boot partition is too full for my Arch Linux system. Thank you for this video I'm going to boot into a GParted iso so I can then give myself more than the standard 20Gb That just doesn't cut it in today's age.

What if my efi is in between system storage, and unallocated space?

[@SheikhAmeen]

Dont mess it up. It's to boot your OS.

[@Ballissle]

I'm having this same issue. But it's on a laptop I'm not too concerned about so will see what happens when the move is completed. Just moving the efi to the left. If it breaks and is not repairable I will just have to completely format the drive and reinstall I guess. I made a backup anyway of files and app manifest.

[@jonathankrimer]

Why and what? Why do we need a partition? Why would we change the size?

Thank you SavvyNik You saved me hours of time waste! Summary This video provides guidance on avoiding common mistakes when working with Linux partitions, particularly for beginners. It emphasizes the use of GParted, handling swap space, and understanding the Linux partitioning scheme. Highlights 💡 Use GParted for efficient partition management. 💡 Be cautious when handling swap space; it may need to be disabled before making changes. 💡 Understand the Linux partitioning scheme and ensure there's no data behind the partition you're extending. 💡 Avoid making changes to EFI partitions or any areas with existing data. 💡 Consider using a live image or disk for partition edits to avoid issues with mounted systems. 💡 Enable swap space after designating it to ensure your system recognizes and uses it. 💡 Linux beginners should follow these guidelines to prevent common pitfalls when working with partitions.

[@SavvyNik]

Glad to hear it. Thanks for the summary!

[@alexstone691]

I appreciate these videos, although they are not for me they will certainly help other people as you explain pretty clearly

[@Evgen13Great]

But you can move swap partition to the end of your disk, can't you?

[@SavvyNik]

Sure but if it used to be at the front you’re going to have incongruent space because there will be a gap between partitions.

[@1q3er5]

@@SavvyNik why do we even need swap partition - why doesn't linux handle it internally

Where is Boot partition?
