Module libcoreinst::blockdev

Structs

• Disk
• Mount
• PartTableKernel
  Device nodes for partitionable kernel devices, managed by the kernel.
• PartTableKpartx
  Device nodes for non-partitionable kernel devices, managed by running kpartx to parse the partition table and create device-mapper devices for each partition.
• Partition
• SavedPartitions

Traits

• PartTable
  A handle to the set of device nodes for individual partitions of a device. Must be held as long as the device nodes are needed; they might be removed upon drop.

Functions

• detect_formatted_sector_size
  Inspect a buffer from the start of a disk image and return its formatted sector size, if any can be determined.
• find_colocated_esps
  Find ESP partitions which sit at the same hierarchy level as device.
• find_efi_vendor_dir
  This is basically a Rust version of: https://github.com/coreos/coreos-assembler/blob/d3c7ec094a02/src/cmd-buildextend-live#L492-L495
• find_parent_devices
  This is a bit fuzzy, but… this function will return every block device in the parent hierarchy of device capable of containing other partitions. So e.g. parent devices of type “part” doesn’t match, but “disk” and “mpath” does.
• get_blkdev_deps
• get_blkdev_deps_recursing
• get_block_device_size
  Get the size of a block device.
• get_filesystems_with_label
  Returns filesystems with given label. If multiple filesystems with the label have the same UUID, we only return one of them.
• get_gpt_size
  Get the size of the GPT metadata at the start of the disk.
• get_sector_size
  Get the logical sector size of a block device.
• get_sector_size_for_path
  Get the sector size of the block device at a given path.
• is_dasd
  Checks if underlying device is IBM DASD disk
• lsblk
• lsblk_single
• udev_settle
