MX, btrfs, and subvolumes

[karens_haircut]

I'm doing a fresh install of MX. I thought I would take a look at btrfs since it seems like there are benefits as far as backups are concerned, but I'm honestly pretty confused.

In the install process for MX, there's an option for btrfs but not for subvolumes. I want / and /home to be separate, but being that MX doesn't offer subvolumes, it seems to me that I should be installing / and /home into separate partitions. But I thought part of the point of subvumes was that I could have one large partition, create two subvolumes within it, and not have to decide on sizes for the volumes.

I've scoped out this guide https://forum.mxlinux.org/viewtopic.php ... fs#p674536 but I'm not trying to encrypt and this guide makes it seem as though it's easy to create subvolumes in MX, just NOT if you're also trying to encrypt. But I don't see the option for creating subvolumes anywhere in the installer. At the bottom of this guide, a dev also posted and said that whatever bug the guide addresses has been fixed. Again, I still see no option for subvolumes.

In this guide, this person creates boot and home partitions and then hacks it together once everything is booted up.. I'm just honestly massively lost here.

All I want, is to create a fresh MX install with two subvumes, and I want to be able to create snapshots once I'm up and running, to back up my data.

You create btrfs-partition by selecting Format and next step right click on the line and create subvolum for '@' root and @home. Do keep label for root-subvol as "@" , which is an requirement for timeshift to work with btrfs, in case you want to use timeshift for fast btrfs backups.

Ok, thanks!

Quick question- I've got btrfs configured. Snapshots with Timeshift are not instantaneous, though - it takes something like one minute to complete a snapshot.

I've posted on reddit about this but didn't get much help. Someone asked me if my distro (MX) uses quotas, in btrfs, by default.

Any idea why snapshots might be taking so long?

Ok, thanks!

Good, so now you have subvolumes created using MX Installer.

Seems something else. Also it is advisable to open a specific thread with describing subject title - reflecting the issue -
and detailed information: like QSI, what timeshift version is in use, etc.
At least it may increase the chance someone with a similar issue would read this new thread and may spot the reason.
Thanks
