	DataDir         string
	SnapstoreConfig *snapstore.Config
}

type DataDirStatus ¶

type DataDirStatus int

DataDirStatus represents the status of the etcd data directory.

type DataValidator ¶

type DataValidator struct {
	Config *Config
	Logger *logrus.Logger
}

func (*DataValidator) Validate ¶

func (d *DataValidator) Validate(mode Mode, failBelowRevision int64) (DataDirStatus, error)

Validate performs the steps required to validate data for Etcd instance. The steps involved are:

Check if data directory exists.
If data directory exists
Check for data directory structure.
If data directory structure is invalid return DataDirectoryInvStruct status.
Check for data corruption.
return data directory corruption status.

type Mode ¶

type Mode string

Mode is the Validation mode passed on to the DataValidator

const (
	// Full Mode does complete validation including the data directory contents for corruption.
	Full Mode = "full"
	// Sanity Mode validates only the data revision against the revision in the backup store.
	Sanity Mode = "sanity"
)
