我试图用MUNIN的SMART Tools插件监视我的两个SAS驱动器。 在SATA驱动器上没有问题,所有SMART值都显示出来。 看来,smartctl不会为SAS驱动器输出有价值的SMART值:
在Debian上挤压两个SAS驱动器“smartctl -A / dev / sda”输出:
smartctl 5.40 2010-07-12 r3124 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Current Drive Temperature: 43 C Drive Trip Temperature: 85 C Manufactured in week 10 of year 2012 Specified cycle count over device lifetime: 50000 Accumulated start-stop cycles: 6 Elements in grown defect list: 0 Vendor (Seagate) cache information Blocks sent to initiator = 765815905320960
在SATA驱动器上没有信息:

SMART在SCSI(SAS)和ATA(SATA)驱动器中以不同的方式实现 – 特别是SCSI驱动器中没有属性的概念。
