Btrfs install. Need assistance

[vince]

Hello!

I need to install the system on a storage pool consisting of 2 disks with Btrfs. Here’s my plan:

• Create a FAT32 partition

• Combine the remaining space into a Btrfs pool with:

  • Metadata in RAID1

  • Data in SINGLE mode

sudo mkfs.btrfs -m raid1 -d single /dev/disk1 /dev/disk2

Then install in manual partition

How can I ensure:

1. Metadata is read primarily from one disk

2. Data is written strictly to the other disk

I think that would be very hard to do in the installer.

I think it would be a lot easier to install with the installer as normal to one disk. Then add the other disk and move the metadata to it.

That being said, why would you want the metadata on one disk and the data on another? Ideally, you would want two copies of the metadata, one on each disk.
