Disks and subvolume

Hi all, my laptom has two dds:

on first one I've created /boot/efi + root
on second hard disk I've created /home

file system btrf

It's normal that in btrfs-assistant I don't see subvolume home?

this is just for know if all is ok

Rgs.

Rob.

Missing garuda-inxi :slight_smile:

Do you use Garuda Linux?

Why you post a picture?

sudo btrfs subvolume list /
lsblk

If you change the defaults, you should know why @home doesn't appear, right?

Sincerly I didn’t know, I’m new to Garuda, is this necessary or is ok?
Eventually is this a problem and how I can fix it?

Must I create also a config for home with:
snapper -c home create-config /home
?

Creating subvolumes on specific directories is made in order to prevent them from being snapshotted. If /home is on a seperate partition, it will not be a part of the OS partition so creating a /home subvolume will be unnecessary.

snapper -c home create-config /home

Usually this is not necessary.

So what do you suggest?
Could you tell me step by step what I must do?

With /home on a separate disk, I believe this is correct and I think you will have to create a subvolume for it first as well since it is a different partition.

The step-by-step guide is here: Snapper - ArchWiki

I'm not able to create subvolume on hdb, there's an already partition and I think that I've made a big trouble, I don't know what I've made but hdb has been fused with hda... ish..
force to use gparder from live distro for create again the two disks..

I don't know how to do, if somebody may explaine me and follow me step by step this should be great.. otherwise never mind

if easy also starting from a new installation

Is it very neccessary for you to have your /home on the bigger ssd?

Otherwise you could just reinstall including /home in your sda and the “problem” is gone.

Then again: Why is it a problem in general? Is it very neccessary for you to be able to use snapper on your /home partition? Because usually it’s used to set the system back after fucking up and /home usually does not get fucked up… ever.

Where exactly do you think you have made an error?

If this is still a question for you I’d answer it - again, as others already did - with no, and suggest moving on.

If you’re unwilling to move on from it, use the link @BluishHumility gave and put in the work. :wink:

Whatever you are attempting to communicate here is unclear. If your disk layout has changed, explain what happened and show:

lsblk -f

and

sudo parted -l
