Restoring an index in an Ubuntu VirtualBox (stuck _restore)

Elastic Stack Elasticsearch
1

Hi everyone,

I have created a snapshot from my index (26Gb) in a MAC OSX. I have an Ubuntu virtual machine running on a external HD with 300Gb.

I have shared the MAC's backup folder with the Ubuntu VM gave the VM user all the rights to access it in /media/sf_shared_backup.

Then, I created a backup in my VM elasticsearch as follows:

PUT 192.168.56.101:9200/_snapshot/my_backup

{
	"type": "fs",
    "settings": {
        "location": "/media/sf_shared_backup",
        "compress": true
    }
}

The shared folder in Ubuntu contains all the index data (26Gb). But when I execute

POST http://192.168.56.101:9200/_snapshot/my_backup/2017-02-24/_restore

Just the index mapping is created!

GET http://192.168.56.101:9200/_snapshot/my_backup/2017-02-24/_status

returns DONE to all shards, but

http://192.168.56.101:9200/delfos_index_homologacao/_stats

returns total = 0 documents created.

Besides that, the elasticsearch in the VM machine doesn't show any error message!

Is there anything I am missing in this process?

Thanks

Instead of sharing the backup folder, I've made a scp and copy all the snapshot to Ubuntu VM.

And unfortunately, anything changed.

Trying to clear a little....

As you can see, it seems the _restore process has already finished, but

GET http://192.168.56.101:9200/delfos_index_homologacao/_stats

returns

{
    "_shards": {
    "total": 10,
    "successful": 0,
    "failed": 0
    },
    "_all": {
    "primaries": {},
    "total": {}
    },
    "indices": {}
    }

And when I try to delete the snapshot, I've just got the following exception:

DELETE http://192.168.56.101:9200/_snapshot/my_backup/2017-02-24/

{
  "error": {
    "root_cause": [
      {
        "type": "concurrent_snapshot_execution_exception",
        "reason": "[my_backup:2017-02-24/gl7LdKEaTRGYiTBqdGOC1w] cannot delete snapshot during a restore"
      }
    ],
    "type": "concurrent_snapshot_execution_exception",
    "reason": "[my_backup:2017-02-24/gl7LdKEaTRGYiTBqdGOC1w] cannot delete snapshot during a restore"
  },
  "status": 503
}

Is it still running or not? Is it stuck? But why did I get a SUCESS on _snapshot _status method??

I didn't restore it using wait_for_completion....

So, it's being very hard to figure out what is going on here.

Does anybody can give a hint?

Thanks a lot,

Guilherme

Thank you guys, but everything is ok now!

I don't know why the _status method returned SUCCESS before the shards have all documents allocated.

But anyway, it's working as expected!

Thank you!
