[Bug 237701] sysutils/smartmontools: Causing controller resets

--- Comment #1 from Dan McGrath <danmcgrath.ca at gmail.com> ---
It seems that the system has been much better since removing the line:
  daily_status_smart_devices="...."

from the /etc/periodic.conf. I suspect that past issues with these systems
(Zabbix alerts during maintenance times) may have actually been coming from IO
stall outs during the periodic runs that were invoking the smart status.

Interestingly enough, running `smartctl -i /dev/da#` alone doesn't cause the
problems, but it was only a recent update to the smartmontools that started to
populate the daily logs, which in turn caused the errors, that started to
reveal a potentially old bug.

For some extra background, these R410's have HW Raid capable HBA cards in them,
but were configured as non raid, which appeared to pass it through fine (at
least enough to give me output in smartctl. 

My guess is smartctl doesn't like something about these particular devices. The
are technically in IR mode, not IT, yet allow SMART to be queried. Maybe there
is some issue with this? I don't know, you guys are the experts, so I can only
give some historical insights and technical info.

Hope it helps!
