| node_xfs_extent_allocation_extents_allocated_total | 为文件系统分配的extent数 在电脑文件系统中，一个 Extent (在中国大陆某些文献中翻译为“区块”[1])，是指一段连续的存储空间。一般来说，一个文件的物理大小一定是一个 extent 容量的整数倍。当一个进程创建一个文件的时候，文件系统管理程序会将整个 extent 分配给这个文件。当再次向该文件写入数据时 (有可能是在其他写入操作之后)，数据会从上次写入的数据末尾处追加数据。这样可以减少甚至消除文件碎片。 参考：http://www.wikiwand.com/zh-sg/Extent_(%E6%AA%94%E6%A1%88%E7%B3%BB%E7%B5%B1) | # HELP node_xfs_extent_allocation_extents_allocated_total Number of extents allocated for a filesystem. |
