specify critical temperature alarm SSD!=HDD

[John Doe]

Hi
I would like to set critical alarm temperature for HDD to 40 degree Celsius and for SSD to 55.
Unfortunately I can only find a general setting which is applicable for all drives. Is there a way to adjust this?
with every scrub i get alerts from my SSDs

Unfortunately not. Although that is a reasonable feature request.

Your only option, if you insist on 40C as "critical", is perhaps to disable SMART applying to the SSD's. You can do this in Storage->View Disks.

But, 40 is hardly critical. I wouldn't want to run my drives 24/7 at 40C, of course, but occasionally hitting 40C wouldn't blow them away. You might consider raising the critical number to 45C----assuming that's high enough to avoid the triggering during a scrub.

I do agree with you though that this should be possible to do---there's lots of us now (myself, m0nkey, etc) that have hybrid vdevs, both spinning rust and SSD for pool storage. So this makes sense. Did you want to put a feature request in at bugs.freenas.org?
