BlockUtilsError

DeviceState

DeviceType

What type of device has been detected.

Filesystem

This allows you to tweak some settings when you’re formatting the filesystem

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
