parkverbot是一个守护进程,以防止在旋转介质的硬盘磁头停泊。现代旋转硬盘有一个不好的特性,涉及定时自动卸载磁头,由SMART属性“Load_Cycle_Count”衡量。这会导致其他问题(也不能总是被关闭)间的延迟唤醒。将定期发出parkverbot守护小的读取请求,以防止将其头部卸载闲置状态的硬件。
parkverbot is a daemon that prevents hard disk head parking in rotational media. Modern rotational hard disks have a misfeature involving the regular automatic unloading of the heads, measurable by the SMART attribute "Load_Cycle_Count". This causes latency on wake-up amongst other issues (and it cannot always be turned off). The parkverbot daemon will periodically issue small read requests in order to keep the hardware from going to its head-unloaded idle state.
