SCSI Sense: MEDIUM ERROR asc:11, 0 Error Message

[jay-zzz]

I searched a few posts and googled a few things and found this post which most relates to my issue. However this post doesn’t discuss my current situation - which is I can’t start FreeNAS to perform any tests.

I boot the current version of FreeNAS server and via the IPMI I see the following error:
----------------

At this point the server is stuck and doesn’t boot up. After reading the post listed above, it appears as though three 3TB WD Red drives might have failed? Currently, I can’t log in to GUI or via SSH. FreeNAS won’t load.

If so, what should I do now? Has the 8gb Patriot brand flash drive from Fry’s gone bad?

EQUIPMENT:
Processor - Intel Pentium G3220 3.0 GHz Dual Core Intel HD
Motherboard - Supermicro MBD -X10SLL +F -O UATX
RAM - Crucial 16 GB 240 pin DDR3 SDRAM ECC Unbuffered Server Memory
Storage - WD Red 3 TB drives X 6 = 18 TB total / Used about 2 TB so far.
Software - FreeNAS 9.3

History: Server was installed with 6 WD 3TB Network NAS HDDs using Raid Z2 - so about 12TB are useable, which means I have two drive fail redundancy, right?

I should probably add that the server was working the last time I powered it on 5 days ago. The one thing I did (in hind sight it was a dumb thing to do) was lift the rear end of the server and lean it forward, while it was running, to plug the network cable that got disconnected for some reason. From that point onward, I was unable to access the server via GUI or SSH.

I’m still under the 1 year warranty with the WD drives, however my bigger and more important issue is to somehow ‘fix’ the drives so the boot process can run the FreeNAS software. After I get the server online, I’d like to perform a manual backup of the data onto another machine then send the ‘bad’ drives back to WD for replacement (if that’s what the error messages above translate into). Obviously, I don’t want to lose the data on the drives. I really don’t know what I’m doing when it comes to Raid and restoring bad drives, etc.

Any help and direction would be greatly appreciated. In advance - Thank you for your spending your time and helping me find a solution!!

 

[Ericloewe]

No SAS controllers? If not, it sounds like your boot device needs fixing.

 

[jay-zzz]

Eric,

Thanks for the advice, I bought a new usb flash 16gb drive and installed FreeNAS 9.3 onto it then uploaded my configuration file. Voila! Everything started working again. This ‘shutdown’ has got me thinking...I’d like to check the integrity of my drives. Do you know how to run commands via GUI or via SSH to check the status of my drives to verify if they are failing?

 

[Bidule0hm]

See the Boot tab (in the System tab) in the web GUI ;)

 

[jay-zzz]

@Bidule0hm, I visited the Boot tab within the System tab and it doesn’t show me the integrity of the HD drives. All it says is “healthy”. Which I’m assuming is referring to the NEW 16GB USB Flash Drive I installed an hour ago. (See image) Am I missing something on this page?

I suppose I should be more specific in my question. Is there a way to ‘test’ the existing WD 3TB HDs via the command line? And based on the output of such a test, be able to extract that drive #2 is 80% healthy, while drive #5 is 20% healthy. This way I can start to plan for drive replacements?

 

[Bidule0hm]

Oh, you talk about the data drives, sorry.

Yes, you can see the pool status by using the command zpool status and the drives SMART values with the command smartctl -a /dev/da0 (you need to change the da0 by your drive name of course). But you need to setup SMART tests and scrubs in the web GUI if you want the result of these commands to be useful. Note that if something bad happens the server will send you an email (if it's correctly configured in the web GUI) ;)

@Bidule0hm: Under Storage > Scrubs | I have one set for my ZFS volume to perform a check every 1st and 15th at 3:15am indefinitely. The server also has my email listed correctly to notify me if there are any issues. I did receive an email once indicated the temperature was getting too hot. So I know it works. I did add more fans and solved the over heating issue.

I ran the command smartctl -a /dev/ada0 (my drives are from ada0-ada5) and here’s the output:

QUESTION: Is there anything that stands out to you?? I see a couple of areas that say “Pre-fail”, “Old_age” in the Vendor Specific SMART Attributes with Thresholds section.
.... wait I thought I was describing me for a sec....pre-fail....old age...lol...anyways, should I be worried about these results??

I ran the same code on all the drives and they say pretty much the same thing. I did notice that all the drives also stated:
SMART overall-health self-assessment test result: PASSED

QUESTION: drives ada0 & ada1 both run at 6.0 Gb/s while ada2-ada5 run at 3.0 Gb/s. Is this a problem and what can/should I do to make them all run at 6.0 Gb/s?

 

[Bidule0hm]

I don't see anything to worry about.

You've correctly setup the email, scrubs and SMART tests so everything is ok ;)

If you want to be informed of the SMART and/or zpool status after each test you can add a custom script and a cron task to email you the values, see the Useful Scripts link in my sig ;)

Regarding your 6/3 Gb/s question I would say nothing, the speed is probably limited by the controller or the drives because it's the max speed it can achieve. If you're sure both are 6 Gb/s then it's the cable, try a better cable certified for 6 Gb/s :)

 

[jay-zzz]

Thanks for your help thus far!

I downloaded the SMART script from your ‘useful scripts’ section. I put the files in /root/scripts/smart.report.sh and when I run it I get this error:

Code:

[root@NAS-Server] ~/scripts# ./smart.report.sh

awk: no variable name

Heres how I listed the drives in the script:

drives="ada0 ada1 ada2 ada3 ada4 ada5”

also tried with the path:
drives="/dev/ada0 /dev/ada1 /dev/ada2 /dev/ada3 /dev/ada4 /dev/ada5"

but I get the same error. What am I doing wrong? :(

 

[Bidule0hm]

The first method (without the /dev part) is the right one.

Can you post the output of cat -e smart.report.sh please? I suspect a copy-paste problem, it happens all the time...

 

[jay-zzz]

I got the .sh file working. I used the Raw paste data located at the bottom of your script. Then I clicked ‘clone this paste’. I copied that text directly into the smart.report.sh file on the FreeNAS server, ran the file and all went fine!

Cheers!!! :) :) :)

 

[Bidule0hm]

The $ signs is the -e option on cat, it's very useful to see where there is newlines chars :)

So yeah, copy-paste problem. I've reduced the length of the longest lines in the SMART and ZPool scripts to avoid that, it should be ok if you recopy it from the pastebin now ;)

Edit: you've been faster than me :p So yeah, the CLI built-in to the web GUI is full of bugs, try to learn how to use Putty to SSH to the server, it'll save you some troubleshooting time ;)

 

[jay-zzz]

I should have used the scp command via SSH to transfer the file...don’t know why I didn’t. :|

It’s been several minutes and I have not yet received the email regarding the report. Is there a setting that I need to check / uncheck in GUI?

 

[Bidule0hm]

You've replaced the fake email by your email at the top of the script?

You should receive the email a few seconds (depends on your email box, etc...) after running the script manually. If it works you can add a cron task (don't forget to put the absolute path to the script instead of ./ for the cron) ;)

 

[jay-zzz]

yup

Same email address as the one used in the GUI?

Checked that it's not in the spams?

I did use the same one in the GUI then I tried another email address - same result. Also double checked the spam box.

I figured out what went wrong. You said something about my email address being the same as in the GUI which prompted me to double check what was in the GUI. System > Email and for some reason the ‘Use SMTP Authentication’ was unchecked. I check the box, entered in the info and all is good now. Email is sent instantly once I run the script.

Really weird that this info did not get updated when I imported my configuration file after upgrading the USB flash drive. Nonetheless, another lesson learned!

Thanks for all your help!!! :)
