Keepstore can store data in local and network-attached POSIX filesystems.
Volumes are configured in the
Volumes section of the configuration file. You may provide multiple volumes for a single keepstore process to manage multiple disks. Keepstore distributes blocks among volumes in round-robin fashion.
Volumes: - # The volume type, indicates this is a filesystem directory. Type: Directory # The directory that will be used as the backing store. Root: /mnt/local-disk # How much replication is performed by the underlying filesystem. # (for example, a network filesystem may provide its own replication). # This is used to inform replication decisions at the Keep layer. DirectoryReplication: 1 # If true, do not accept write or trash operations, only reads. ReadOnly: false # When true, read and write operations (for whole 64MiB blocks) on # an individual volume will queued and issued serially. When # false, read and write operations will be issued concurrently. # # May improve throughput if you experience contention when there are # multiple requests to the same volume. # # When using SSDs, RAID, or a parallel network filesystem, you probably # don't want this. Serialize: false # Storage classes to associate with this volume. See "Storage # classes" in the "Admin" section of doc.arvados.org. StorageClasses: null # Example of a second volume section - DirectoryReplication: 2 ReadOnly: false Root: /mnt/network-disk Serialize: false StorageClasses: null Type: Directory
