Restore data on disk

Hi guys,

I am new to elastic search. I found that some indexes from the logstash
were missing this morning. So I looked at the
'$ES_Home/data/elasticsearch/nodes/0/indices/' directory:

https://lh3.googleusercontent.com/-2B9ZkpRhj0Y/U-4tZ2MRLUI/AAAAAAAAANQ/2I3oBgTlh8E/s1600/56.jpg

And I looked at node 1's data directory at
'$ES_Home/data/elasticsearch/nodes/0/indices/' and it shows:

https://lh4.googleusercontent.com/-We9Llyrym3A/U-4uF-XGGSI/AAAAAAAAANY/hrbKaVvmZDs/s1600/78.jpg
Yet in Kibana and kopf, I can only see all the indexes coming from node 1.
I don't know why node 1 is missing all the logstash indexes from 2014.07.01
to 2014.08.12.

How can I retrieve those indexes in node 0?

All I can remember is on Aug.13th. When I came, the logstash data from
2014.07.01 to 2014.08.12 are not shown in my Kibana interface anymore. I
thought it was deleted but later I found the data was actually in node 0.
Can anybody tells me why this is happenening?

Thanks!

Yuheng

Hi Chenlin,

Thank you! I did not find any interested message in the elasticsearch.log.
It is just filled with warning messages.

I would like to join the QQ group, but I submitted join request to the QQ
group and have not been approved.

best,

Yuheng
