[pve-devel] [PATCH installer 1/2] raid setup: btrfs: do not allow legacy BIOS boot on 4Kn disks

[Christoph Heiss]

This is already checked for LVM and ZFS setups, but not for Btrfs. Add
it there too, as it doesn't work anyway.

Tested by creating a block device with 4K sectorsize using
the following QEMU args:
  -device virtio-blk,drive=testdrive4k,logical_block_size=4096,physical_block_size=4096
  -drive file=/path/to/4k-testdisk.img,if=none,id=testdrive4k

The 4k-testdisk.img was created with:
  qemu-img create -f qcow2 /path/to/4k-testdisk.img 16G
