3. Start Minio server [This is a test purpose setup, not recomemnded for anything else.]

minio server ~/data1 ~/data2 ~/data3 ~/data4
Initializing data volume.

4. Setup Minio Client configuration.

4.1 Add host alias [This might be different in your setup]

mc config host add myminio http://127.0.0.1:9000 PDRME539X2A6SR1MKTL6 cQlPVKB9BxQMmLpN3ya8SsBmOkhfTAxd0DXDacwz

4.2 Add a bucket

mc mb myminio/bucket1

4.3 Add object to bucket

mc cp linux-amd64.tar.gz myminio/bucket1

4.4 Minio Heal Command

Note: In our example

::Disc/Data Directories are::

/home/ubuntu/data1
/home/ubuntu/data2
/home/ubuntu/data3
/home/ubuntu/data4

::Bucket is::

bucket1

::Object inside bucket 1 is::

linux-amd64.tar.gz

Scenario 1: Heal an object.

mc ls myminio/bucket1
[2017-03-24 13:24:25 IST]  80MiB linux-amd64.tar.gz

Now let us remove object "linux-amd64.tar.gz" from "/home/ubuntu/data1".

$ ls data1/bucket1/
linux-amd64.tar.gz
$ rm -r data4/bucket1/linux-amd64.tar.gz
$ ls data1/bucket1/ [Because object is deleted]

$ mc admin heal myminio/bucket1
Object bucket1/linux-amd64.tar.gz is healed.
$ ls data1/bucket1/
linux-amd64.tar.gz

Scenario 2:Heal a bucket.

 mc ls myminio/bucket1
[2017-03-24 13:24:25 IST]  80MiB linux-amd64.tar.gz

Remove the bucket name "bucket1" forcefully from ''data1`` disc.

$ ls data1/bucket1/
linux-amd64.tar.gz
$ rm -r data1/bucket1/
$ ls data1/
$ mc admin heal myminio/bucket1
Object bucket1/linux-amd64.tar.gz is healed.
$ mc ls myminio
[2017-03-24 18:54:25 IST]     0B bucket1/

Heal the disk

$ rm -r data1/
$ mc admin heal myminio  [This will bring back data1 disc]

heal bucket and objects on data1 disk.

$ mc admin heal  -r myminio/
Object: bucket1/linux-amd64.tar.gz, can be healed.

For more usage information run command below to your terminal :

$ mc admin heal
