Hi,
I have a Elasticsearch Cluster of 2 nodes. I have configured them to store
data at the location which is /auto/share. I want to point one of the two
nodes in the cluster to some other location to store the data say /auto/foo.
What would be the best way of achieving the above task without loosing any
data.? And is it possible to do that without loosing any data.?
Thank you,
Shriyansh

Do you want to copy the existing data in /auto/share to /auto/foo, or start
with no data?

I would prefer with no data in /auto/foo.? But would like to go with way,
which is efficient and more reliable.

If you want no data in /auto/foo then just create the directory, give it
the right permissions and then update the config to point to it.
It's the same process you did for /auto/share.
Do you have replicas set on your indexes?

Yes, I have set _index.number\_of\_replicas: 1_. If I just point one of the 2
nodes to some other location, wont it loose the data stored by that node.?

If you point the instance to a new data location then yes, it will startup
with no data, but it won't lose the data completely as it will still be
located in your original /auto/share directory.
However given you have replicas set what will happen is when the node
starts up pointing to the new location it will simply start to copy the
data from the other node so that you fulfil your replica requirements.

As you mentioned the node will not lose the data completely, is there any
possibility that it will lose some data.?
Thank you,

To make sure if /auto/share goes down, I have data in /auto/foo. And I am

This is why you have replicas, they give you redundancy at a higher level
that the filesystem,
If you are still concerned then you should add another node and increase
your replicas.
Playing around on the FS to create replicas is only extra management
overhead and likely to end up causing more problems than it's worth.

#### Post date: [August 19, 2014, 2:12am UTC](https://discuss.elastic.co/t/how-to-safely-migrate-from-one-mount-to-another-mount-in-elasticsearch-to-store-the-data/19335/13 "2014-08-19T02:12:20Z")
I got your point sir, but if my entire /auto/share goes down. Then I wont
have any chance to recover the data in /auto/share.
Is there any other way to recover the data.?
Thanks,
Shriyansh
