====== parted ====== * [[fdisk]] * [[gdisk]] * [[grub]] * [[grub2]] * [[sfdisk]] Note: from a personal point-of-view, I use ''gdisk'' over ''parted''; ''gdisk'' lets you examine changes more closely, while ''parted'' commands will often not ask for prompts. Syntax: ''parted [options] [device [command [options ...] ...]'' Options: * **-l** - list partition layouts on all block devices * **-a** or **--alignment** - set alignment type for newly created partitions * **none** - use the minimum amount allowed by the disk type * **cylinder** - align partitions to cylinders * **minimal** - use minimum alignment as given by the disk topology information * **optimal** - use optimum alignment as given by the disk topology information Commands: * **[device]** - block device to use; if none given, uses first block device * **[command [options]]** * **print** - display the partition table * **mkpart** part-type [fs-type] start end - create a new partition of type primary, logical, or extended, beginning at ''start'' and ending at ''end''. Default unit is megabytes. * **align-check** type partition - check if partition satisifies the alignment contraint of type * **mklabel** lable-type - create a new disklabel / partition table of label-type. fex: bsd, gpt, msdos * **name** partition name - set the name of partition to name - supported by GPT, but not MBR * **resizepart** start end - set the end position of partition -- this does not modify the filesystem on the partition * **rm** partition - delete the partition * **select** device - choose device as the current one to edit * **set** partition flag state - set the flag on a partition: boot, root, swap, hidden, raid, lvm, legacy_boot, etc. State should be either 'on' or 'off'. * **unit** unit - set unit as the display type; fex: 's' for sectors, 'B' for bytes, 'kB', 'MB', 'GB', 'TB', '%' of device size * **toggle** partition flag - toggle the state of flag on a partition Display the partition table of ''/dev/sdc'': parted /dev/sdc print Create a new, empty partition table on a device with GPT. **Note that this will remove all existing partitions.** parted /dev/sdc mklabel gpt ** Sample walkthrough ** Final format: 1 MB boot partition used by GRUB, a 128 MB partition for the kernel and GRUB2 cnofig, mounted by OS as ''/boot'', a 2 GB swap partition, and the remaining space for the root partition, mounted at ''/''. Wipe the partition table, create a 2MB primary partition used by GRUB2 (not /boot), starting at the 1st MB and ending at the 2nd, name it ''grub'', and set the ''bios_grub'' label on: parted /dev/sdc mklabel gpt parted /dev/sdc mkpart primary 1 3 unit MB name 1 grub set 1 bios_grub on parted /dev/sdc mkpart primary 3 131 name 2 boot parted /dev/sdc mkpart primary 131 2179 name 3 swap
