Dir LayoutΒΆ
The directory layout of an installation is as follows:
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 |
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 location with greatest free space. Note, there is 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 raids and the like. Here is how it is configured:
path.data: /mnt/first,/mnt/second
Or the in an array format:
path.data: [“/mnt/first”, “/mnt/second”]
