关于Load_Cycle_Count

waterloo2005 · 发表于 2010-11-1 01:24:40

while true; do smartctl -a /dev/sda | grep 193; sleep 30; done;
通过这个命令查看发现大概每分钟两次。正常吗？
我启用了laptop-mode . 在laptop mode 设置中设置了：

#
# Power management for HD (hdparm -B values)
#
BATT_HD_POWERMGMT=254
LM_AC_HD_POWERMGMT=254
NOLM_AC_HD_POWERMGMT=254

复制代码

按说设成254硬盘应该不停的.

irc上有人说: spinning up and down is not necessarily related to load cycle count

大家的这个数值是多少?谢谢

254不行，试一下255那是我试的值，我正在把笔记本当家用服务器。
anyway，最好去硬盘厂商那里看一下说明。

以前也关注和折腾这个问题。现在不管了。。。

# cat /etc/conf.d/hdparm

# Note that options such as -y which force *immediate* power saving options
# should generally not be placed here. The hdparm init.d script may run at
# anytime with respect to other init.d scripts that do system wide drive
# scans (like the hald script), so they will merely get spun right back up.
# If you wish to use these options, please use the local.start init.d script
# instead so that you're guaranteed that it will run last.
#
# You can either set hdparm arguments for each drive using hdX_args,
# discX_args, cdromX_args and genericX_args, e.g.
#
# hda_args="-d1 -X66"
# disc1_args="-d1"
# cdrom0_args="-d1"
# or you can set options for all PATA drives
pata_all_args="-d1"
# or you can set options for all SATA drives
sata_all_args=""
# or, you can set hdparm options for all drives
all_args="-B255 -M128"

复制代码

如此設置之後，wd硬盤那個不斷增加的值就很正常了。

那么我需要/etc/init.d/hdparm start 吧？谢谢

答案是。其实不要太不这个值的事情放在心上。

多少年的伪科学了，怎么还有人关注……

难道这个不影响硬盘寿命吗?谢谢
