No, they are mounted inside of /. mounted and nested are totally different.
I guess i don’t understand.
To be clear, you don’t need to understand any of this to use the tool. It “just works”
The only rule is that you can’t have something permanently mounted at /.snapshots in fstab.
So i just have to remove this line in fstab so it’s not mounted? Other than installing your package what else do i need to do? Enable the btrfs- something.service?
UUID=314dd67c-2060-4f55-8afe-edeacc8d15d6 /.snapshots btrfs subvol=/@snapshots,defaults,noatime,autodefrag,compress=zstd 0 0
Since you have a custom setup, that happens to be customized in the one way the app doesn’t support, you need to undo those customizations.
LIke this:
sudo umount /.snapshots
sudo mkdir /mnt/btrfs
sudo mount UUID=314dd67c-2060-4f55-8afe-edeacc8d15d6 /mnt/btrfs -o subvolid=5
sudo mv /mnt/btrfs/@snapshots /.snapshots
sudo umount /mnt/btrfs
Then remove that line from /etc/fstab

It’s taking a while to move the @snapshots. Also I haven’t installed your package yet. Was i supposed to do that first?
Err…it really shouldn’t be. It should be instant unless it is doing something wrong.
No, it doesn’t matter.
[ricklinux@eos-kde ~]$ sudo umount /.snapshots

[ricklinux@eos-kde ~]$ sudo mount UUID=314dd67c-2060-4f55-8afe-edeacc8d15d6 /mnt/btrfs -o subvolid=5
[ricklinux@eos-kde ~]$ sudo mv /mnt/btrfs/@snapshots /.snapshots
Edit: I don’t know what it’s doing?
Edit2: Probably going to be ruined now.
Something is wrong if it is taking a while. Is your disk getting full? I hope it isn’t copy all the data…
Worst case is you lose the snapshots. It shouldn’t otherwise hurt your install.
So what do i do? ctrl c
I would.
I don’t mind reinstalling and starting from the beginning. My installs are 3-4 minutes. If i reinstalled with Btrfs what do i have to do to set it up compared to what i’m doing here? Or what should i do?
I tried the command again
[ricklinux@eos-kde ~]$ sudo mv /mnt/btrfs/@snapshots /.snapshots
[sudo] password for ricklinux:
mv: inter-device move failed: '/mnt/btrfs/@snapshots' to '/.snapshots/@snapshots'; unable to remove target: Directory not empty
[ricklinux@eos-kde ~]$
Edit: Must have moved something.
I might as well start from something that is correct if I’m going to test it don’t you think?
Okay i reinstalled kde on btrfs.
[ricklinux@eos-kde ~]$ cat /etc/fstab

So what are all the things i have to do.

I ended up reinstalling but i really don’t know how to set this up again to work with this. It’s really discouraging.
Based on the screenshots he provided, I assume you just need to click the buttons to enable the features such as snapper time and snapper cleanup.
I wouldn’t enable the balance feature because, in my opinion, it’s just not necessary for a single ssd drive.
I would tune the cleanup settings accordingly.
I wouldn’t turn on the scrub feature because I would like to know when it’s running to avoid slowdowns or even reboots during the process.
I would turn on fstrim as based on Dalto post above, it doesn’t hurt to have fstrim and discard=async running together…
This is how I would use it… It’s my personal preference, and the nature of a personal preference is that is not perfect for everyone, and also I would change it and tune it accordingly over time…
I reinstalled with kde and btrfs but there is no /.snapshots folder. I’m trying to understand is everything here that that is needed. Do i have to install snapper? I did but I’m not sure if that program already pulls it in. Does it automatically create the configs? I really don’t know what to do.
Let me check, I’ll install it here to find it out.
Maybe it’s a requirement, I remember a pacman -Qs snapper that would show that, not sure if the pacman command is right to check the requirements…
Sorry, I was away for a while.
If you re-installed, all you need to do is install snapper and btrfs-assistant-git
Once you do, if you run btrfs Assistant, you can create the snapper configs you want right in the gui.
