ExportDirectory recursively writes its contents into a tar Writer.

ExportFile writes a file into a tar Writer.

FindMount mounts a path based on the relative location of the nearest driver.

GetDriver returns the driver from path <root>.

GetLastIOStat returns the iostat device utilization reports.

GetStatus retrieves the status for the volumeNames passed in.

ImportArchive reads from a tar Reader and writes the contents into a path preserving file permissions and ownership.

ImportArchiveHeader imports a tarfile header to a particular path.

InitDriver sets up a driver <name> and initializes it to <root>.

InitIOStat starts the iostat call and passes the close signal when sent.

IsBtrfsFilesystem determines whether the path is a btrfs filesystem.

IsDir() checks if the given dir is a directory.

Mount loads, mounting if necessary, a volume under a path using a specific driver path at <root>.

Register registers a driver initializer under <name> so it can be looked up.

Registered returns a boolean indicating whether driver <name> has been registered.

RunBtrFSCmd runs a btrfs command, optionally using sudo.

ShutdownAll shuts down all drivers that have been initialized.

ShutdownDriver shuts down an existing driver and removes it from our internal map.

SplitPath splits a path by its driver and respective volume.

Unregister the driver init func <name>.

This struct is stupid, for the sake of using interfaces AND RPC ser/deser.

TenantStorageStats represents tenant-specific storage usage details.

Driver is the basic interface to the filesystem.

Volume maps, in the end, to a directory on the filesystem available to the application.

DriverInit represents a function that can initialize a driver.

DriverType represents a driver type.

FileInfoSlice is a os.FileInfo array sortable by modification time.

UsageData implements Unmarshaler allowing us to unmarshal a []Usage indirectly.
