Fields

id: String

Identifier.

name: String

Human friendly name.

disk_type: DiskType

Disk type.

block_size: u64

Block size in bytes.

num_of_blocks: u64

Count of block.

status: u64

Disk status stored in bitmap. Valid status value are:

• Disk::STATUS_UNKNOWN
• Disk::STATUS_OK
• Disk::STATUS_OTHER
• Disk::STATUS_PREDICTIVE_FAILURE
• Disk::STATUS_ERROR

• Disk::STATUS_MAINTENANCE_MODE
• Disk::STATUS_SPARE_DISK
• Disk::STATUS_RECONSTRUCT
• Disk::STATUS_FREE

if (d.status & Disk::STATUS_OK) == 0 {
    println!("Disk {}/{} is not healthy", d.name, d.id);
}

system_id: String

Identifier of owner system.

location: Option<String>

Disk location in storage topology.

rpm: Option<i32>

Disk rotation speed - revolutions per minute(RPM):

• -1 – Unknown RPM speed.

• 0 – Non-rotating medium (e.g., SSD).

• 1 – Rotational disk with unknown speed.

• > 1 – Normal rotational disk (e.g., HDD).

link_type: Option<DiskLinkType>

Disk data link type.

vpd83: Option<String>

SCSI VPD 0x83 NAA type identifier. Udev treat it as ID_WWN_WITH_EXTENSION

Implementations

impl Disk

pub const STATUS_UNKNOWN: u64 = 1u64

Plugin failed to query out the status of disk.

pub const STATUS_OK: u64 = 2u64

Disk is up and healthy.

pub const STATUS_OTHER: u64 = 4u64

Vendor specific status.

pub const STATUS_PREDICTIVE_FAILURE: u64 = 8u64

Disk is still functional but will fail soon.

pub const STATUS_ERROR: u64 = 16u64

Error make disk not functional.

pub const STATUS_REMOVED: u64 = 32u64

Disk was removed by administrator.

pub const STATUS_STARTING: u64 = 64u64

Disk is starting up.

pub const STATUS_STOPPING: u64 = 128u64

Disk is shutting down.

pub const STATUS_STOPPED: u64 = 256u64

Disk is stopped by administrator.

pub const STATUS_INITIALIZING: u64 = 512u64

Disk is not functional yet, internal storage system is initializing this disk, it could be:

• Initialising new disk.

• Zeroing disk.

• Scrubbing disk data.

pub const STATUS_MAINTENANCE_MODE: u64 = 1_024u64

In maintenance for bad sector scan, integrity check and etc It might be combined with Disk::STATUS_OK or Disk::STATUS_STOPPED for online maintenance or offline maintenance.

pub const STATUS_SPARE_DISK: u64 = 2_048u64

Disk is configured as spare disk.

pub const STATUS_RECONSTRUCT: u64 = 4_096u64

Disk is reconstructing its data.

pub const STATUS_FREE: u64 = 8_192u64

Indicate the whole disk is not holding any data or acting as a dedicate spare disk. This disk could be assigned as a dedicated spare disk or used for creating pool. If any spare disk(like those on NetApp ONTAP) does not require any explicit action when assigning to pool, it should be treated as free disk and marked as Disk::STATUS_FREE | Disk::STATUS_SPARE_DISK.

Trait Implementations

impl Clone for Disk

fn clone(&self) -> Disk

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Disk

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl<'de> Deserialize<'de> for Disk

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

impl Serialize for Disk

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
