Hi,

 

I've installed Unraid 4.5.6 under VMware esxi 4.1 (now support USB device so... that's cool) and assigned a few raw device disk to it. Everything work just fine except for the temperature which is always showing 0. I was thinking it may be because of the virtualization layer but... smartctl is reporting the temperature correctly so I don't understand why this utilities can get the info but not Unraid. Does somebody have an idea?

 

The other thing that may be related is Unraid doesn't seems to be able to get the disks to spin down. Is there a way to force a spin down with smartctl or another utilities running on Unraid so that I try it outside of the WebGUI and see if I'm getting the same result?

 

Now, my question regarding the full slackware distro is about which version should I use if I want to try this with Unraid 4.5.6? And what about 5.0 beta?

 

If going the full distro road, is there any drawback at running Unraid directly from the full distro at all time instead of using this only as a development environment?

 

 

Thank you

try hdparm -y and the device name as in /dev/sd? or /dev/hd? where ?=letter of drive you are accessing.

 

I have my unRAID setup running under Slackware 13.1 (Current) without issue. If you feel up to it, you can even use the Slackware 13.1 64bit distro : http://lime-technology.com/forum/index.php?topic=5639.0

 

The wiki instructions are for 12.2, but unRAID itself uses some newer subsystems like udev which is closer to the latest Slackware 13.x versions.

Hi,

 

I've tried the hdparm -y and here is what I'm getting:

 

/dev/sdc

issuing standby command

SG_IO: bad/missing ATA_16 sense data:: 70 00 00 00 00 00 00 18 00 00 00 00 00 00 00 00 00 00 09 0c 00 00 00 00 00 00 00 00 00 00 40 50

HDIO_DRIVE_CMD(standby) failed: Input/output error

 

I've done the same on two drives (one Seagate and one WD) and it is the same error. So, my first guess is that the spin down can't work with RDM (Raw Device Mapping) SATA drives. Is it supposed/known to work?

 

Any idea about the temperature?

 

The smartctl is reporting me a lot of stuff with the record "194 Temperature_Celsius" returning a value which is not shown in the gui.

 

Thank you.
