Subject: [PATCH] Add SMART self-test results to zpool status -c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Add in SMART self-test results to zpool status|iostat -c. This
works for both SAS and SATA drives.
Also, add plumbing to allow the 'smart' script to take smartctl
output from a directory of output text files instead of running
it against the vdevs.
