Hello everyone, I’m installing Fedora. I have 2 disks, one 500 GB and another 1 TB. I’m using the Advanced Custom partitioning option to set up the 500 GB disk with /boot/EFI, swap, and /, and I want the 1 TB disk for /home. However, when I’m creating / and /home, under Device Type, I see three options: Partition, LVM2 Volume group, and Btrfs Volume. I want to use Btrfs for Fedora, so my question is, should I choose Partition under Device Type and select Btrfs for the Filesystem, or should I choose Btrfs Volume group under Device Type? How should I proceed for both / and /home individually when creating them?
If you wish to have both / and /home totally separate you should probably use ext4 for /home so the btrfs volume does not span both drives. If you use one btrfs volume to span both drives then the data will span both drives as well.
I do not know if you can create more than one btrfs volume while doing the installation. I personally choose to never span drives with anything less than raid 5 since raid0 and btrfs volumes that span drives simply add to the potential for failure with additional failure points within a single file system and no redundancy.
Another method may be to install everything on one drive then after the installation completes create a partition on the second drive and mount it as /home to replace the one created by default.
