Smartmontools Documentation

Manpages

If you are having trouble understanding the output of smartctl or smartd, please first read the manual pages installed on your system:

  man 8 smartctl
  man 8 smartd
  man 5 smartd.conf

Here are on-line versions of the smartmontools man pages:

​man/smartctl.8.html smartctl manual page
​smartd manual page
​smartd.conf manual page

Note that these are the manual pages for the current version of smartmontools in the developers SVN repository; they might not correspond to the (possibly older) version of smartmontools installed on your system. So the manual pages installed on your system should be regarded as definitive for your installation.

SMART Attributes

Different vendors, different interpretation.. The raw SMART attributes (temperature, power-on lifetime, and so on) are stored in vendor-specific structures. Sometime these are strange. Hitachi disks (at least some of them) store power-on lifetime in minutes, rather than hours. IBM disks (at least some of them) have three temperatures stored in the raw structure, not just one. And so on.
If you find strange output, or unknown attributes, please look in the below listed pages with vendor specific info.
When you don't find an answer to your question there, send an email to ​smartmontools-support and we'll help you try and figure it out.
