## 6. Heal operations
|
||||
|
||||
<a name="Heal"></a>
|
||||
### Heal(bucket, prefix string, healOpts HealOpts, clientToken string, forceStart bool, forceStop bool) (start HealStartSuccess, status HealTaskStatus, err error)
|
||||
|
||||
Start a heal sequence that scans data under given (possible empty)
|
||||
`bucket` and `prefix`. The `recursive` bool turns on recursive
|
||||
traversal under the given path. `dryRun` does not mutate on-disk data,
|
||||
but performs data validation.
|
||||
|
||||
Two heal sequences on overlapping paths may not be initiated.
|
||||
|
||||
The progress of a heal should be followed using the same API `Heal`
|
||||
by providing the `clientToken` previously obtained from a `Heal`
|
||||
API. The server accumulates results of the heal traversal and waits
|
||||
for the client to receive and acknowledge them using the status
|
||||
request by providing `clientToken`.
|
||||
|
||||
__Example__
|
||||
|
||||
``` go
|
||||
|
||||
opts := madmin.HealOpts{
|
||||
Recursive: true,
|
||||
DryRun: false,
|
||||
}
|
||||
forceStart := false
|
||||
forceStop := false
|
||||
healPath, err := madmClnt.Heal("", "", opts, "", forceStart, forceStop)
|
||||
if err != nil {
|
||||
log.Fatalln(err)
|
||||
}
|
||||
log.Printf("Heal sequence started at %s", healPath)
|
||||
|
||||
```
|
||||
|
||||

# MinIO Admin Library. [](https://slack.min.io)
|

# Golang Admin Client API Reference [](https://slack.min.io)
|
||||
The MinIO Admin Golang Client SDK provides APIs to manage MinIO services.
|
||||
|
||||
This quickstart guide will show you how to install the MinIO Admin client SDK, connect to MinIO admin service, and provide a walkthrough of a simple file uploader.
|
||||
|
||||
This document assumes that you have a working [Golang setup](https://docs.min.io/docs/how-to-install-golang).
|
||||
|
||||
## Download from GitHub
|
||||
|
||||
```sh
|
||||
|
||||
go get -u github.com/minio/minio/pkg/madmin
|
||||
|
||||
```
|
||||
|
||||
## Initialize MinIO Admin Client

## 6. Heal operations
|
||||
|
||||
<a name="Heal"></a>
|
||||
### Heal(bucket, prefix string, healOpts HealOpts, clientToken string, forceStart bool, forceStop bool) (start HealStartSuccess, status HealTaskStatus, err error)
|
||||
|
||||
Start a heal sequence that scans data under given (possible empty)
|
||||
`bucket` and `prefix`. The `recursive` bool turns on recursive
|
||||
traversal under the given path. `dryRun` does not mutate on-disk data,
|
||||
but performs data validation.
|
||||
|
||||
Two heal sequences on overlapping paths may not be initiated.
|
||||
|
||||
The progress of a heal should be followed using the same API `Heal`
|
||||
by providing the `clientToken` previously obtained from a `Heal`
|
||||
API. The server accumulates results of the heal traversal and waits
|
||||
for the client to receive and acknowledge them using the status
|
||||
request by providing `clientToken`.
|
||||
|
||||
__Example__
|
||||
|
||||
``` go
|
||||
|
||||
opts := madmin.HealOpts{
|
||||
Recursive: true,
|
||||
DryRun: false,
|
||||
}
|
||||
forceStart := false
|
||||
forceStop := false
|
||||
healPath, err := madmClnt.Heal("", "", opts, "", forceStart, forceStop)
|
||||
if err != nil {
|
||||
log.Fatalln(err)
|
||||
}
|
||||
log.Printf("Heal sequence started at %s", healPath)
|
||||
|
||||
```
