queryStatvfs

protected long[] queryStatvfs(String path)

Description copied from class: LinuxFileSystem

Queries filesystem statistics for the given mount path.

Returns an array of [totalInodes, freeInodes, totalSpace, usableSpace, freeSpace], or null on failure (the caller will fall back to File methods for space values).

Specified by:
