Question: How to merge 2 btrfs partions using subvolumes? in c/[email protected]
[–] [email protected] 1 points 3 weeks ago

What I ended up doing:

  • Moving the root partition from one partition to the other, using btrfs send | btrfs receive
  • Updated fstab to use the correct partitions
  • The computer kept using the old root partition then booting, I had to use ubuntu's boot repair (https://help.ubuntu.com/community/Boot-Repair) to fix that
  • I probably should have moved the home partition instead of the root one. I would have avoided much trouble.

My understanding is that trams are much more cost effective long-term than buses, because the rails last much much longer than asphalt or even concrete.

They also have other benefits:

  • Smoother, less bumpy ride
  • Bigger capacity than buses, with the possibility to add up to 5 cars
  • Don't have to wait at traffic lights (We can install sensors to detect a tram is coming and switch the light so that it can go ahead without waiting. That's technically doable for an BRT/SRB, but it's more complex and as you can see, they didn't do it for SRB Pie-IX...🙁)
  • Less noisy
  • Easier to electrify
  • Easier to automate (make them self-driving)
  • No tires means less pollution
  • Grass can be added between the 2 rails, making it more pleasant looking, absorbing heat and noise
  • Level boarding make them more accessible
  • and more

Can I do this while the system is running? I guess it would be safer to boot to a liveUSB before attempting this?

Also, what do you mean by "After a rebuild of the initrd" ? That's something I have to do after editing fstab? How do I do that?

Question: How to merge 2 btrfs partions using subvolumes? (lemmy.ca)
 

Hi! I'm learning how to use btrfs and I need some advice.

One one of my desktop, I made the mistake of creating 2 partitions, one for /(root) and one for home. Both are btrfs. I didn't know that I could use subvolumes so that they could share the same physical space.

My question: How can I merge the root and home btrfs partitions into only 1 partition that would use btrfs subvolumes?

I'm looking for something like that:

  • Partition1 (btrfs)
    • subvolume 1: @root (mounted to /)
    • subvolume 2: @home (mounted to /home)
  • Partition 2, 3, 4...

My current setup:

  • 1 physical hard drive (1 TB), shown as sda below
  • The partitions I want to merge are sda7 and sda8
  • That computer is an iMac also running MacOS so it has a few other partitions that I should not touch
$ lsblk

Ça serait vraiment bien. Les tramways ont beaucoup d'avantages par rapport aux autobus.

The reason places are too sparse is because cars. They take too much space.

I remember reading that city taxes should change from being based on the value of the building to only be based on the value of the land. This way it discourages only single-family homes.

Shouldn't we be switching buses with light railway? in c/[email protected]
[–] [email protected] 8 points 1 year ago (1 children)

Tramways and Light Rails are much more silent and comfortable. Rails are smooth, no pothole etc. They are also much much more durable than asphalt.

Rails take less space and can be covered with grass/greeneries. Looks prettier and absorb heat.

Plugin or app to transcribe hand written text (lemmy.ca)

I'm wondering if there is a way in Joplin (or with another app?) to transcribe hand written text Into plain text.

Basically, I'd like to have an archive copy of my personal journal in Joplin.

I would greatly prefer something open source that runs locally. Ideally free or cheap.
