Topology modes
- single: One eligible disk. Create BIOS boot (if enabled), ESP 512 MiB, remainder as data. Make a btrfs filesystem labeled ZOSDATA on the data partition.
- dual_independent: Two eligible disks. On each disk, create BIOS boot (if enabled) + ESP + data. Create a separate btrfs filesystem labeled ZOSDATA on each data partition. No RAID by default.
- ssd_hdd_bcachefs: One SSD/NVMe and one HDD. Create BIOS boot (if enabled) + ESP on both as required. Create cache (on SSD) and data/backing (on HDD) partitions named zoscache and zosdata respectively. Make a bcachefs filesystem across both with label ZOSDATA, using SSD as cache/promote and HDD as backing.
- btrfs_single: One eligible disk. Create BIOS boot (if enabled), ESP 512 MiB, remainder as data. Create a btrfs filesystem labeled ZOSDATA on the data partition.
- bcachefs_single: One eligible disk. Create BIOS boot (if enabled), ESP 512 MiB, remainder as data. Create a bcachefs filesystem labeled ZOSDATA on the data partition.
- dual_independent: Two eligible disks. On each disk, create BIOS boot (if enabled) + ESP + data. Create an independent btrfs filesystem labeled ZOSDATA on each data partition. No RAID by default.
- bcachefs_2copy: Two eligible disks. Create data partitions on both, then create a single multi-device bcachefs labeled ZOSDATA spanning the data partitions (two-copies semantics to be tuned via mkfs options in a follow-up).
- ssd_hdd_bcachefs: One SSD/NVMe and one HDD. Create BIOS boot (if enabled) + ESP on both as required. Create cache (on SSD) and data/backing (on HDD) partitions named zoscache and zosdata respectively. Create a bcachefs labeled ZOSDATA across SSD(HDD) per policy (SSD cache/promote; HDD backing).
- btrfs_raid1: Optional mode if explicitly requested. Create mirrored btrfs across two disks for the data role with raid1 profile. Not enabled by default.
