Functions ¶

func Init ¶

func Init(t cluster.Target, config *cmn.Config,
	allowSharedDisksAndNoDisks, useLoopbackDevs, ignoreMissingMountpath bool) (created bool)

initializes mountpaths and volume; on SIE (storage integrity error) terminates and exits

func RecoverTID ¶

func RecoverTID(generatedID string, configPaths cos.StrSet) (tid string)

pre-loading to try to recover lost tid

Types ¶

type VMD ¶

type VMD struct {
	Version    uint64                `json:"version,string"` // version inc-s upon mountpath add/remove, etc.
	Mountpaths map[string]*fsMpathMD `json:"mountpaths"`     // mountpath => details
	DaemonID   string                `json:"daemon_id"`      // this target node ID
	// contains filtered or unexported fields
}

VMD is AIS target's volume metadata structure

func LoadVMDTest ¶

func LoadVMDTest() (*VMD, error)

func NewFromMPI ¶

func NewFromMPI(tid string) (vmd *VMD, err error)

MPI => VMD

func (*VMD) JspOpts ¶

func (*VMD) JspOpts() jsp.Options

func (*VMD) String ¶

func (vmd *VMD) String() string
