New page

As I work more and more with direct disk access filesystems (ie ZFS) I find a need to keep tabs on my disks. The following was created as a side project to keep an eye on my home server that have hard to reach drives, so knowing when one is about to fail is important.

The first version prints out in the terminal
*The device
*Whether or not it has passed overall SMART health assessments
*and all previous test results.
Frankly this is not very elegant and is not presented in a clean manner but it is a start.
