I’ve had the same thing happen before.

Sounds like a nice setup

Simon,

I am not sure how that managed to sneek into my copy paste but it’s not in the file, I found a workaround and have just manually polled each drive.

Being none critical I just wanted to see what the drives were running at since i built the new box, 20x hotswap rackmount case, drives are averaging 32*C…. not bad at all

Hi bigt, it looks like the ^M (control M) characters need to be removed from the file.

Cheers,
Simon

Simon,

Great set of guides thusfar, though I am having a few issues with your script, and have grown bored of googleing.

I have copy pasted your script into a file, edited in my drive ID’s and chmodded the file to make it executable. Though upon execution i receive the following error “xxx@xnet:/tank1/dump/temp# ./test.sh
bash: ./test.sh: /usr/bin/bash^M: bad interpreter: No such file or directory”

I have confirmed that my default shell is Bash, as well as tryed changing to the sh shell and it gives the same error.

Removing that line from the script also nets me the following error;
“./test1.sh
: command not found
: command not found
‘/test1.sh: line 5: syntax error near unexpected token `{
‘/test1.sh: line 5: `drivetemp () {
”

Hope that you can point me in the right direction as I am kind of at a loss here

Hey meow, did you enable AHCI in the BIOS? Try typing ‘format’ and then CTRL-C out of it, and look at the drive listing to see if it is showing your drives as legacy IDE devices — i.e. not running in proper PCI mode. Did that change anything?

Cheers,
Simon

I had the same problem as “Mark on July 8th, 2009 at 19:56″. So then I did this command, and got this output:

Glad it worked ono, I must fix that script as it is presented here — I think the quotes got translated when displayed on this page…

And thanks Gustavo for the fix !

Thanks, and good luck with completing the build of your ZFS NAS.

Mark, what type of sata controller are you using? I seem to remember reading that SMART isn’t supported with Intels ICHx controllers. Perhaps this has changed, but something to look into.

Excellent work on the articles Simon. I purchased a 1tb WD green drive and an integrated Jetway board a little over a year ago with the intent to eventually do raid 5 under Ubuntu. Soon after I learned about ZFS and shot that plan to heck.
Unfortunately, with my college student budget I haven’t been able to purchase a new chip or the rest of the drives yet, but when the day comes I’m sure I will be referring to your site quite often.

Thank you Gustavo! i replace the slanted quotes with regular and:

~# ./temps.sh
Drive c0t0d0 temp is 29C

weee!

Simon, thank you very much for the script!

Hello,

I am also new to *nix world (OpenSolaris 2009.06). I have installed smartmontools and created/copied your script, but i only get following output (no temperatures are listed):

Kren@model:~/Scripts# ./Temp.sh
Drive c7d0 temp is
Drive c7d1 temp is
Drive c8d0 temp is
Drive c8d1 temp is

Thank you and kind regards,
Mark

Yes, you need to edit the code in a text editor. The last printf and let lines have slanted double-quotes, instead of regular double-quotes, thus the operand error.

By: Simon

Simon — Mon, 06 Jul 2009 14:36:22 +0000

Don’t know why that didn’t work for you — perhaps a typo? You could maybe try copying and pasting the whole text into a file and re-running it.

Hi!
im a super newbie at this, and i have troubles running the script.
it says:
“Drive./temps.sh: line 23: let: “index: syntax error: operand expected (error token is ““index”)
in a neverending loop until i hit ctrl+c

have tried with just one drive in the drives=() array

Thanks Simon for the write up. I found it very useful, having just built a 4 disk zfs pool, in a case which doesn’t have the best airflow…the temps ended up being lower than I expected (approx 30 degrees) ) I did have some initial problems compiling, but I was originally compiling with suncc. I installed gcc and no problems with the compile.

Regards
Tim

Thanks, and glad you found the info useful. I spent a lot of time finding all this stuff out, so I’m happy for others to benefit from it. I found a lot of info on other bloggers’ sites to help me too.

And thanks again for the SunRay info — sounds good, and if I’m ‘allowed’ to obtain any more hardware, like a SunRay, I’ll be sure to write something about it. Cheers! I’ll take a peek on ebay now or craigslist

And thanx a lot for your blogg! Tons and tons of useful information. Godsend. I had problems setting up CIFS, but now I will try again with that. We all help each other. You give us tips. And we give tips back. Together we all prosper. This is the open community. The more we give, the more we get back. Easy.

Would be cool if you tried SunRays and blogged about them too. )

Well, they really do sound like cool devices. I had heard the name SunRay but so far I’ve never seen one. I’m off to Google to take a look. Four watts power consumption is incredibly low power, and for what most people use a computer for, it sounds quite sufficient, assuming you have a server to connect it to.

Thanks a lot for the tips!

But if SRSS is fixed so it can show video full screen, then I shall get a OH projector connected to SunRay so I can watch movies on the entire wall. A quad core with 8GB RAM should suffice for my entire household, and several discs in ZFS raid. And the movies on it, plus the MP3 collection. Sweeeeeet!

SunRay 2FS has dual Screen dvi, each 1920 x 1200.

(No I dont work at SUN, I am just a SUN fanboy, i like the best technology. Right now, it is SUN having the best technology).

Maybe you can lower the resolution on one SunRay down to 640×480 and then you have full video? Lower the bit plan from 24 bit to 12 bit?

The SunRay 2 is 0.380 kg, and the size of a video VHS cassette. You can have dozens of them in a drawer, if the need should arise, for dozens of new workstations to work on.

There are problems with watching video on them. The bandwidth is the problem. The SunRay 2 has a 100mbit NIC built in. If you watch video, 1024 x 768 at 24bits, then it is like 100MB/sec? That is too much, because the server sends bitmaps to the SunRay. But if you have a small windows, you can see flawless video. The greater you make the window, it will start to lag. I think ~640×480 video window is flawless.

However, SUN is modifying the server SunRay SRSS software so it can show video fullscreen. I dont know when it is scheduled to be released. filibeto.org has a mailing list for SunRay.

You just install SRSS software on the server, and answer like 4 questions, and you are done. Then you insert the SunRay into the hub and thats it. Dead simple. The SRSS software is free to download from sun.com.

Ive heard of a bank that swithed to SunRays, and they saved 94% of their energy bill.

One quad with some GB, and you can serve several SunRays doing heavy duty work. One machine with two quad cores and 16 GB RAM in the basement, and you can serve your whole neighbourhood. They can toss out all their computers, and have a SunRay from you. And several large discs with ZFS at your house, with quotas, and they can listen to music, see video (on small windows), surf, etc. 4 Watt each SunRay. You can not upgrade the SunRay, you upgrade the server instead, and all SunRays will be upgraded. To serve many SunRays, ive heard RAM is the most important. Maybe 300 MB RAM for each user, or so is sufficient. Each SunRay uses like 320kbit/sec bandwidth for normal use, which is less than Citrix. There is a blogg on Citrix vs Sunray bandwidth flash video, and SunRay wins. Citrix is unusable at 20kbit/sec – contrary to what citrix claims. See the blogg where they try first with 20kbit/sec on citrix.

There are lots of user storys on blogs on SunRay. I love them. No one can mess the server up anymore. It is Solaris. And ZFS gives them a quota. Totally safe and top notch security. SunRay can also use cards (like Visa card) and support hot desking. Pull it out, and into another SunRay and continue where you left off. SUN has like 19.000 SunRay deployed worldwide, and have 38 administrators for them in total. Where small work.

Sounds very interesting — I will check them out. Thanks for the tip! I suppose you can’t watch video on them, can you?

Have you considered using thin client SunRays connected to your server? They dont have any CPU nor RAM (that runs software). You can not upgrade them, impossible. They only transmit the mouse and keyboard data into the server, and the server sends back bitmaps to the SunRay. Totally secure.

You plug in a SunRay into the hub and 10 secs later you get a login screen. Thats it. Looks exactly like you are sitting in front of the server. Each SunRay 2, uses 4 Watt. No fans. One server in the basement + 4 SunRay + ZFS = veeeery nice. With Virtualbox on the server you can run WinXP too. An refurbished SunRay can be found on Ebay for 40 USD. I use SunRays at home, and it is soooo sweet. You can listen to your MP3 collection on your ZFS pool from each room.

There are lots of interesting blogs on SunRay from home users.
