Functions ¶
func DirSizeOnDisk ¶
DirSizeOnDisk calculates the total size of a directory on disk, including its subdirectories. TODO: We should also calculate and include `xattr` size.
func GetFSUsedPercentage ¶
func New ¶
func New(num int) (IOS, BlockDevices)
Types ¶
type AllDiskStats ¶
type BlockDevices ¶ added in v1.3.24
type BlockDevices []*blockDev
type IOS ¶ added in v1.3.16
type IOS interface {
GetAllMpathUtils() *MpathUtil
GetMpathUtil(mpath string) int64
AddMpath(mpath, fs string, label Label, config *cmn.Config, blockDevs BlockDevices) (FsDisks, error)

DiskStats(m AllDiskStats)
}

type Label ¶ added in v1.3.23
type Label string
Introduced in v3.23, mountpath labels are used to deliver extended (mountpath usage related) functionality that includes:
- mapping of the mountpath to its underlying disk(s), if any (potentially useful in highly virtualized/containerized environments);
- disk sharing between multiple mountpaths;
- storage classes (as in: "different storages - for different buckets");
- user-defined grouping of the mountpaths (e.g., to reflect different non-overlapping storage capacities and/or storage classes)
In v3.23, user-assigned `ios.Label` simply implies that user takes a full responsibility for filesystem sharing (or not sharing) across mountpaths
