Ok, so the temperature on my Disk 1 is no longer showing up on the web GUI. So before it stopped showing up, I installed unMenu and attempted to create a user share. However, I had not formatted the hard-drive and before I figured this out I restarted the server, without restarting unMenu. I then rebooted again at some point to see if the user share was on the flash drive.  I formatted the HDD and started a pre-clear of my Disk 2. This was at about 11:15 this morning, the HDD temp was showing. I then left and went to the gym, when I came back around 2:00 PM I found just a star for my Disk 1 HDD temp. I tried stopping and starting the array and reopening the web GUI but that didn't work. I did some searching and found to check that SMART is enabled for the drive. So I used a telnet connection  to run the smartctl -a -d ata /dev/sdb command which showed that SMART is indeed enabled. As it had been when I pre-cleared the drive. It also showed the HDD temp to be 28C.

In the "Device Is" category it says: "Not in smartctl database [for details use: -P showall]" I tried to type "-P showall" in the command line, but I got "-P: command not found"

 

I haven't found any posts (or I lack the searching skills) that give any other explanations for why this has happened.

 

Also, a bit off topic but will the fact that I ran a telnet session while a pre-clear was running affect the pre-clear?

 

And I couldn't find more detailed info on the telnet session, so my questions are: Once I'm done running the telnet commands can I just close the window and the pre-clear or whatever else that may be running will just keep on chugging along? How many telnet sessions can I have open at once?

 

Thanks

You would have to have typed:

smartctl -P showall

When the drives go to sleep their temperature is not accessible.  (with a few exceptions but unRAID just displays the temperature as "*" when the drive is sleeping.  Otherwise if it attempted to read the temperature most drives would spin up.)

Also, a bit off topic but will the fact that I ran a telnet session while a pre-clear was running affect the pre-clear?

Nope... it will have no effect.

And I couldn't find more detailed info on the telnet session, so my questions are: Once I'm done running the telnet commands can I just close the window and the pre-clear or whatever else that may be running will just keep on chugging along? How many telnet sessions can I have open at once?

Nope... If you close the window the process will terminate.  You must leave it open for the entire duration.  However you can install "screen" and run your pre-clear sessions under it as described in the preclear thread to be able to run virtual screen sessions and disconnect/reconnect as you described though. 

 

As fat as telnet sessions, I think you'll be limited to 6 telnet sessions but I might be wrong.

Thanks, this was the case. I spun up the drive and the temp was displayed again. Is this in the documentation some place? I've been looking all over.

I started the pre-clear on the server console with a keyboard connected to the computer. I opened the telnet from my laptop (without screen) to look at the disk1 information while the disk2 drive is being prepared. I thought screen was just used for opening multiple command lines on the same computer. Should I have used screen for this second window even though it was opened on a different computer?

 

Since there is nothing running in the telnet window except the root @ Tower# prompt I can close it because it was only used to look at Disk 1 Smart data? Or because a process(preclear NOT started through telnet) is still being run directly on the server the open telnet session can't be closed since it uses the console as well?

 

I'm also having a hard time finding what the correct way is to close a telnet window (have not used it before). Can I just click on the X at the top of the window? I would think this wouldn't close the process started on the UnRaid Server when the window was opened. The info in the wiki on telnet just says where you can download putty and that is can be used to run the console from another computer, unless I'm missing something.

Perhaps you did not look in the wiki in the Official-Manual here:

http://lime-technology.com/wiki/index.php?title=UnRAID_Manual#Temperature

It is described in the section labeled "Disk Status: Temperature"

That is good it can run as long as it needs.

I opened the telnet from my laptop (without screen) to look at the disk1 information while the disk2 drive is being prepared. I thought screen was just used for opening multiple command lines on the same computer. Should I have used screen for this second window even though it was opened on a different computer?[if you did not need to look at the display you are fine but "screen" is perfect to allow you to start a session on the console and later connect to it on the laptop. 

 

Since there is nothing running in the telnet window except the root @ Tower# prompt I can close it because it was only used to look at Disk 1 Smart data?

Yes you can close it.

Or because a process(preclear NOT started through telnet) is still being run directly on the server the open telnet session can't be closed since it uses the console as well?

Closing it only affects processes started on it.

I'm also having a hard time finding what the correct way is to close a telnet window (have not used it before). Can I just click on the X at the top of the window?

Yes you can.  You can also first exit the session by typing:

exit

at the command line.  Another way is to type

CONTROL-D

at the command line (Hold the "control" key down and press the letter "D")

I would think this wouldn't close the process started on the UnRaid Server when the window was opened.

Ending the session regardless of how sends a "hangup" signal to all the processes started from that session.  Unless a program is specifically coded to ignore that signal they terminate themselves.

The info in the wiki on telnet just says where you can download putty and that is can be used to run the console from another computer, unless I'm missing something.

Telnet is on most computers... but it is a very basic program and provides few extra capabilities. (The function keys will not work on programs you invoke in the telnet window)

 

putty is a more full featured telnet client program.  The function keys will work.

Thanks for all the help Joe.

Surprisingly, I did look at that multiple times, but I some how missed it even though that is pretty much the only info there. Guess I'm becoming brain dead
