Elastic Stack Elasticsearch

Hello,

Can anyone explain the different between "available_in_bytes" and "free_in_bytes" as used in the Nodes API: https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-stats.html#fs-info

free and available are respectively defined in terms of Java's FileStore#getUnallocatedSpace() and FileStore#getUsableSpace():

fsPath.free = adjustForHugeFilesystems(nodePath.fileStore.getUnallocatedSpace());
fsPath.available = adjustForHugeFilesystems(nodePath.fileStore.getUsableSpace());
