== Directory Layout
|
|
|
|
The directory layout of an installation is as follows:
|
|
|
|
[cols="<,<,<,<",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`
|
|
|
|
|*work* |Temporal files that are used by different nodes. |`{path.home}/work` |`path.work`
|
|
|
|
|*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"]
|
|
----------------------------------------
