== Directory Layout
|
|
|
|
The directory layout of an installation is as follows:
|
|
|
|
[cols="<h,<,<m,<m",options="header",]
|
|
|=======================================================================
|
|
| Type | Description | Default Location | Setting
|
|
| home | Home of elasticsearch installation. | | path.home
|
|
|
|
| bin | Binary scripts including `elasticsearch` to start a node. | {path.home}/bin | | conf | Configuration files including `elasticsearch.yml` | {path.home}/config | path.conf
|
|
|
|
| data | The location of the data files of each index / shard allocated
|
|
on the node. Can hold multiple locations. | {path.home}/data| path.data
|
|
|
|
| logs | Log files location. | {path.home}/logs | path.logs
|
|
|
|
| plugins | Plugin files location. Each plugin will be contained in a subdirectory. | {path.home}/plugins | path.plugins
|
|
|=======================================================================
|
|
|
|
The multiple data locations allows to stripe it. The striping is simple,
|
|
placing whole files in one of the locations, and deciding where to place
|
|
the file based on the value of the `index.store.distributor` setting:
|
|
|
|
* `least_used` (default) always selects the directory with the most
|
|
available space +
|
|
* `random` selects directories at random. The probability of selecting
|
|
a particular directory is proportional to amount of available space in
|
|
this directory.
|
|
|
|
Note, there are no multiple copies of the same data, in that, its
|
|
similar to RAID 0. Though simple, it should provide a good solution for
|
|
people that don't want to mess with RAID. Here is how it is configured:
|
|
|
|
---------------------------------
|
|
path.data: /mnt/first,/mnt/second
|
|
---------------------------------
|
|
|
|
Or the in an array format:
|
|
|
|
----------------------------------------
|
|
path.data: ["/mnt/first", "/mnt/second"]
|
|
----------------------------------------
