## `LOCAL_STORAGE_PERCENTAGE`

Option | `LOCAL_STORAGE_PERCENTAGE`
Description | Sets a limit to the percentage of disk full
Default | `85 %`
Minimum | `0 %`

Used to set the percentage of local disk to be used to store incoming data before it is sent to bucket storage.

ini

    LOCAL_STORAGE_PERCENTAGE=80
    LOCAL_STORAGE_MIN_AGE_DAYS=0

These settings only take effect when bucket storage is enabled. It allows LogScale to delete files from the local storage and load them from bucket storage if the files are required during a query. Fetching the file from bucket is much slower than using local storage. Segment files will be deleted in a least recently used order, in order to hit the configured fill target.

In clusters where `USING_EPHEMERAL_DISKS` is `true`, setting `LOCAL_STORAGE_PERCENTAGE` enables prefetching on node recovery, meaning that when a node with an empty disk boots into the cluster, it will start fetching from bucket storage to fill its disk.

### Note

With larger drive sizes, set `LOCAL_STORAGE_PERCENTAGE` to some number close to but smaller than 100 (e.g. 93) to avoid wasted storage.
