Struct DeviceStatsCommand 

pub struct DeviceStatsCommand {
    pub check: bool,
    pub reset: bool,
    pub tabular: bool,
    pub offline: bool,
    pub path: PathBuf,
}

Show device I/O error statistics for all devices of a filesystem

Reads per-device counters for write, read, flush, corruption, and generation errors. The path can be a mount point or a device belonging to the filesystem.

With –offline, reads stats directly from the on-disk device tree without requiring a mounted filesystem.

Fields

check: bool

Return a non-zero exit code if any error counter is greater than zero

reset: bool

Print current values and then atomically reset all counters to zero

tabular: bool

Show stats in a tabular format with columns instead of per-device lines

offline: bool

Read stats from the on-disk device tree (no mount required)

path: PathBuf

Path to a mounted btrfs filesystem or a device/image file
