Struct ZfsPool 

pub struct ZfsPool {
    pub name: String,
    pub state: String,
    pub devices: Vec<ZfsDevice>,
    pub scan: Option<String>,
    pub data_errors: Option<u64>,
    pub size_bytes: Option<u64>,
    pub allocated_bytes: Option<u64>,
}

A ZFS pool and its health.

Fields

name: String

Pool name (e.g. "tank").

state: String

Health as zpool status shows it: ONLINE, DEGRADED, FAULTED, OFFLINE, UNAVAIL, REMOVED or SUSPENDED.

devices: Vec<ZfsDevice>

Its vdevs and devices as zpool status lists them, top to bottom (empty where zpool could not be run, and from agents before 0.26).

scan: Option<String>

The last or running scrub or resilver (“scrub repaired 0B in 00:00:01 with 0 errors on …”, “resilver in progress … 42.1% done”), from the scan: line.

data_errors: Option<u64>

Permanent data errors (errors: N data errors); None unknown.

size_bytes: Option<u64>

Size and space in use (zpool list).

allocated_bytes: Option<u64>

Implementations

impl ZfsPool

pub fn layout(&self) -> Option<String>

The layout of its data vdevs: “raidz1”, “mirror”, “2 × mirror”, “stripe” (devices directly under the pool), or None when unknown.

pub fn has_errors(&self) -> bool

Whether zpool status reported data errors or device errors, which a healthy-looking ONLINE state does not show.

pub fn troubled_devices(&self) -> impl Iterator<Item = &ZfsDevice>

Its devices (not vdevs) with errors or in a bad state.

pub fn is_online(&self) -> bool

Whether the pool is healthy.

pub fn is_failing(&self) -> bool

Whether the pool lost redundancy or data is at risk (worse than an administratively offline pool).
