Subject Re: Running Multiple Solr Instances

Hey Ganesh,

This was not for clustering.I do not think you would need clustering with
solr cloud.With solr cloud when  you create a collection from  scratch  it
creates the data directories under solr home.Now if your drives are mounted
as (/d/1,/d/2  etc) you would want to use all the storage available for
indexes apart from any system resources.So we just created  the collection
and then shut down solr and used symlinks to point to all the mounts.

Thanks,
Nishanth
