BTRFS Please help me access my data

Some time ago I installed Garuda cinamon on my desktop. I deliberately kept /home on a seperate partition - something I always do because I like to be able to swap distros or reinstall without affecting my personal data. Been in this habbit since ext2 was the default linux filesystem.

So today I decided I want to switch to Garuda Dr4gonized Gaming edition. So I reinstalled, using the custom partitioning scheme, I selected each partition for the exact same role and mountpoint as before, and took very great care to make sure I did NOT tell it to format /home.

I used the same username as before.

Yet unlike every other distro I have ever installed, since booting into the new installation, none of the data that was in there seem to be present.

Yet I don’t think it’s REALLY gone - because df shows 1.1Tb of used space on /home so I think some btrfs feature is just masking it - and I am pretty sure it can be recovered. But I’m also very much a noob at bttfs and have no idea where to begin to tell it to take that old home directory and make it my CURRENT home directory, or at least make it visible so I can copy the non-config data out to the new user/home and then destroy the rest.

Please help.

Please post your garuda-inxi as requested by the template.

Have you checked the settings of the partition (for example with gparted/partitionmanager)? It is not really clear what kind of file system the partition has, btrfs? Can you mount the partition (for example via console/dolphin)? Can you access the partition from a live environment?

Are we allowed to see the output or is it top secret?

Hi there, welcome to the forum.
For sure your home partition is not lost and you can reach those data.
The fact is that Garuda uses BTRFS subvolumes, and @home is one of them.
I think the topic has been discussed several times in the forum.
In my opinion the best solution is to just symlink your old home into your home subvolume, but there are several options possible, e.g. you could change your home to the old one changing the fstab.
See e.g.

You might have to chown the old home partition.

You would most likely have to chown them as @filo says but you can pick them easy enough here in settings.
