2014-08-18 Thread Mark Walkom 
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.

 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,

Re: How to safely migrate from one mount to another mount in Elasticsearch to store the data

2014-08-18 Thread Mark Walkom 
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.

Re: How to safely migrate from one mount to another mount in Elasticsearch to store the data

2014-08-18 Thread Mark Walkom 
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?

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


Thank you,

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

How to safely migrate from one mount to another mount in Elasticsearch to store the data

2014-08-18 Thread shriyansh jain 
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
