[SOLVED]Cache Drive temp 0C??

[Capt.Insano]

I picked up a pre-owned PCI-E SATA card for cheap as a quick solution to adding more drives to my  "Intel Corporation - S5500WBV" motherboard.

 

The card is a "Startech 2 Port eSATA + 4 Port SATA II PCI Express x4 SATA Controller Adapter Card" Model #PEXSATA24E

 

Currently I only have 1 drive connected to this card, an SSD that I had to create a cache pool, but the unRAID (6.1.9) WebUI does not report certain info about the drive for example the Temp is reported as 0 degrees C (see below).

 

Is there any solution to this as I had intended on adding more drives to this card?!

 

See details below, if any more details required to debug, please let me know and I will provide.

Any ideas welcome!

 

Thanks a million

That looks like an SSD issue, not all SSDs report temp.

[Capt.Insano]

Ahh!!

 

That is a relief if true because I was going to buy and attach another WD Red 3tb drive for Dual Parity prior to updating to 6.2.

 

Is there any commands I can run to see if this drive offers temp readings?

 

FYI: This is the drive:

It's the SSD, I've used the micron c400, that's the oem version of those and it was the same.

[Capt.Insano]

Perfect,

 

Thanks you for your help!!

Have a look at the SSD's SMART data by clicking on the word "Cache 2" in your screenshot. Scroll down to Attributes and look for item number 194 "Temperature Celsius".

 

[Capt.Insano]

Not there!

 

See attached:

 

Looked at wrong thing, see below

But my other cache drive has the identical listing under "SMART attribute notifications:" and it does report temps??

Click on attributes (or scroll down to it)

[Capt.Insano]

Shite, sorry I was looking in the wrong place.

 

Attached is the atributes of the cache drive NOT reporting temp:

 

194 Temperature celsius is listed

[John_M]

It's listed but it has the value 0. Compare with another device.

[Capt.Insano]

So this 0 value is indicitive of the drive not reporting the temp rather than the PCI-E SATA Card failing to passthrough/report value, yeah?

[JorgeB]

Like I said those SSDs don't report temp, it's not the controller.

[John_M]

If you really want to convince yourself swap it with one of your hard disks.

[Squid]

SMART comes directly from the drive, so if any attribute is reported properly, then the controller is passing through the SMART request.

 

Either that or you live in the arctic.

Thanks a million lads!

 

Always appreciate the support on these boards!
