Struct MdArray 

pub struct MdArray {
    pub name: String,
    pub active: bool,
    pub read_only: bool,
    pub level: String,
    pub members: Vec<MdMember>,
    pub expected_devices: Option<u32>,
    pub working_devices: Option<u32>,
    pub sync: Option<MdSync>,
}

One Linux md array parsed from /proc/mdstat.

Fields

name: String

Array name (e.g. "md0").

active: bool

Whether the array is active.

read_only: bool

Whether the array is read-only (active (read-only) / (auto-read-only)).

level: String

RAID level (e.g. "raid1"); empty for inactive arrays.

members: Vec<MdMember>

Member devices.

expected_devices: Option<u32>

Number of devices the array should have ([n/m] -> n).

working_devices: Option<u32>

Number of devices currently in sync ([n/m] -> m).

sync: Option<MdSync>

Ongoing resync/recovery/reshape/check, if any.
