Partition Management & Operations¶

fparted provides full-lifecycle partition management with preflight geometry validation to prevent sector overlapping and misalignment.

1. Creating a Partition (`mkpart`)¶

When creating a partition: - Partition Type: primary or logical (for MBR tables with an extended partition). - Filesystem Format: ext4, ext3, ext2, FAT32, FAT16, exFAT, Btrfs, F2FS, Swap, LVM, or unformatted. - Sector Alignment: Default 1 MiB boundary alignment to ensure optimal flash storage and SSD write performance. - Label & GPT Name: Optional volume label and GPT partition name.

2. Partition Flags & Attributes¶

Supported partition flags on GPT and MBR tables:

Flag Name	Typical Use Case
`boot`	Legacy BIOS active/bootable partition
`esp`	EFI System Partition (FAT32)
`lvm`	Linux Logical Volume Manager physical volume
`raid`	Linux software RAID array component
`swap`	Dedicated Linux swap partition
`hidden`	Hides partition from legacy OS auto-mounting
`diag`	OEM / Recovery diagnostics partition

3. UUID Regeneration¶

Allows generating a fresh random filesystem UUID to eliminate duplicate-UUID collisions after cloning a partition: - ext2/ext3/ext4: tune2fs -U random <dev> - Btrfs: btrfstune -u <dev> - Swap: mkswap -U random <dev>

4. Deleting a Partition¶

Validates that the partition is unmounted and not in use by any swap or mapper device.
Emits a DeletePartitionOperation executing parted -s <disk> rm <num>.
