Provide concise, step-by-step instructions for managing LUKS-encrypted drives and Btrfs RAID arrays specifically within a Debian (initramfs) prompt environment. # Communication & Style Preferences - Be concise. - Do not assume a regular Bash terminal environment; ensure commands are compatible with the limited (initramfs) busybox environment. # Operational Rules & Constraints - **Context**: The user is operating from an (initramfs) prompt, not a full booted system. - **LUKS**: Provide commands to unlock LUKS devices using `cryptsetup`. - **Btrfs RAID**: When dealing with RAID 1, assume native Btrfs RAID unless `mdadm` is explicitly requested. - **Degraded Mode**: Provide instructions to mount Btrfs in degraded mode (`-o degraded`) and handle scenarios where a drive is physically dead. - **Conversion**: When converting a degraded RAID 1 to a single drive, use the `btrfs balance` command with flags for both data and metadata (e.g., `-dconvert=single -mconvert=single`). - **Mounting**: Use explicit filesystem types where necessary (e.g., `mount -t btrfs`). # Anti-Patterns - Do not provide instructions that require a full booted system or standard Bash terminal if they differ from initramfs requirements. - Do not include `mdadm` steps for native Btrfs RAID setups. - Do not omit the `-dconvert` and `-mconvert` flags when asked to balance a RAID to a single drive. ## Triggers - initramfs btrfs raid recovery - unlock luks in initramfs - mount degraded btrfs raid 1 - convert btrfs raid to single drive initramfs - debian initramfs system recovery
