Crate block_utils

Modules

• nvme

Structs

• AsyncInit
• Device
  Device information that is gathered with udev
• Enclosure
  A raid array enclosure
• ScsiInfo

Enums

• BlockUtilsError
• DeviceState
• DeviceType
  What type of device has been detected.
• Filesystem
  This allows you to tweak some settings when you’re formatting the filesystem
• FilesystemType
  What type of filesystem
• MediaType
  What type of media has been detected.
• MetadataProfile
  This is used for formatting btrfs filesystems and setting the metadata profile
• Scheduler
• ScsiDeviceType
• Vendor
  What raid card if any the system is using to serve disks

Functions

• async_format_block_device
• erase_block_device
• format_block_device
  Synchronous utility to format a block device with a given filesystem. Note: ZFS creation can be slow because there’s potentially several commands that need to be run. async_format_block_device will be faster if you have many block devices to format
• get_all_device_info
  Returns device info on every device it can find in the devices slice The device info may not be in the same order as the slice so be aware. This function is more efficient because it only call udev list once
• get_all_device_info_iter
  Returns iterator over device info on every device it can find in the devices slice The device info may not be in the same order as the slice so be aware. This function is more efficient because it only call udev list once
• get_block_dev_properties
  Get properties for device with devpath device_path (like “/dev/sda”) if present
• get_block_dev_property
  Get property value by key tag for device with devpath device_path (like “/dev/sda”) if present
• get_block_devices
  Scan a system and return all block devices that udev knows about This function will skip udev devices identified as partition. If it can’t discover this it will error on the side of caution and return the device
• get_block_devices_iter
  Scan a system and return iterator over all block devices that udev knows about This function will skip udev devices identified as partition. If it can’t discover this it will error on the side of caution and return the device
• get_block_partitions
  Scan a system and return all block devices that udev knows about This function will only retun the udev devices identified as partition. If it can’t discover this it will error on the side of caution and return the device
• get_block_partitions_iter
  Scan a system and return iterator over all block devices that udev knows about This function will only retun the udev devices identified as partition. If it can’t discover this it will error on the side of caution and return the device
• get_children_devpaths_from_path
  Get the children devices paths from a device path
• get_children_devpaths_from_path_iter
  Get the children devices paths from a device path Note: It has square algorithmic complexity
• get_device_from_path
  returns the device info and possibly partition entry for the device with the path or symlink given
• get_device_info
  Returns device information that is gathered with udev.
• get_mount_device
  Parse mtab and return the device which is mounted at a given directory
• get_mounted_devices
  Parse mtab and return all mounted block devices not including LVM
• get_mounted_devices_iter
  Parse mtab and return iterator over all mounted block devices not including LVM
• get_mountpoint
  Parse mtab and return the mountpoint the device is mounted at. This is the opposite of get_mount_device
• get_parent_devpath_from_path
  get the parent device path from a device path (If not a partition or disk, return None)
• get_scsi_info
  Gathers all available scsi information
• is_block_device
  Checks to see if the subsystem this device is using is block
• is_disk
  check if the path is a disk device path
• is_mounted
  Checks and returns if a particular directory is a mountpoint
• mount_device
  Utility function to mount a device at a mount point NOTE: This assumes the device is formatted at this point. The mount will fail if the device isn’t formatted.
• set_elevator
• sort_scsi_info
  Examine the ScsiInfo devices and associate a host ScsiInfo device if it exists
• sort_scsi_info_iter
  Examine the ScsiInfo devices and associate a host ScsiInfo device if it exists
• unmount_device
• weekly_defrag
