Single partition with Btrfs on MBR-Disk?

Hello guys,

After I screwed my notebook a little and can't find through the problematic areas, I decided to reinstall everything...
I thought about switching to Btrfs and wondered:
I will use a filesystem capable of dynamic subvolumes and I am forced to use MBR partition scheme because my notebook is unable to boot from GPT (already tried that)

Besides I know (at least I think I do) it is possible, would it be "good" to only create one real partition on my disk and create the mount structure with btrfs subvolumes?

Thanks in advance for your help and thoughts about this,

Wolle

No, you can use a gpt partition scheme, just research which bootloaders are able to boot from btrfs and gpt, and whether they can boot from a subvolume or not.

Although, if you're only going to have one partition, do the limitations of MBR really matter?

Also, if your bootloader, kernel, and initramfs are on a btrfs partition, make sure you disable compression on them. It can cause problems.

Thats what my question was: Is it possible to stop bothering with both, logical volumes on MBR and trying to get GPT boot to work, (I tried and was near to throw my notebook out the window) by using Btrfs with a single partition and subvolumes?

Tried to split such a long question sentence...

Re: Single partition with Btrfs on MBR-Disk?

Sorry, I completely misread your first post.

Ask yourself: why do you want to have multiple partitions, and/or think that you have to have them?

Some people have different partitions to keep things separate and orderly, subvolumes are perfect for that. Others use separate partitions to limit the amount of space a certain part of the system (e.g. logs/cache) can take up, subvolumes have this ability, but I don't think it's quite stable yet.
