Asahi Installed - Can I now increase allociated GB?

Hi All…

Vary new to Linux, but LOVE this project. Have installed on my MBP M1… now I need to INCREASE my storage as I only gave it 40GB to try it out at installation… Is this possible… if so, how… ?

Thanks healps… really want to move from macOS to Asahi :]


Yes, you can increase the storage capacity by rebalancing the BTRFS filesystem.

First, create a volume with the desired capacity in MacOS.

Next, switch to Asahi and type lsblk to view device information containing the volume.

zram0        252:0    0     8G  0 disk [SWAP]
nvme0n1      259:0    0 931.8G  0 disk
├─nvme0n1p1  259:1    0   500M  0 part
├─nvme0n1p2  259:2    0 301.6G  0 part
├─nvme0n1p3  259:3    0   2.3G  0 part
├─nvme0n1p4  259:4    0   500M  0 part /boot/efi
├─nvme0n1p5  259:5    0  1000M  0 part /boot
├─nvme0n1p7  259:7    0 463.2G  0 part
└─nvme0n1p10 259:8    0     5G  0 part
nvme0n2      259:9    0     3M  0 disk
nvme0n3      259:10   0   128M  0 disk

Assuming the device is /dev/nvme0n1p7, add it to btrfs devices.

sudo btrfs device add /dev/nvme0n1p7 /

Afterwards, you balance the endpoint by:

sudo btrfs filesystem balance /

Finally, your storage increased.

Hi HH… Thanks for the reply.

I have next to no linux experience, so did NOT manage to get the above instructions to work. It wanted me to add a “-f” and other commands, which lead to a fail. So I went the other way, removed all the partitions from macOS side, then did a fresh install.

I have FINALLY left macOS after 25 years, and am now 100% on Linux, and now with 250 GB drive space :] I have just spent two days configing Asahi and am LOVING IT.

Thanks again…
