SMART daemon crashes when trying to read my SSD

[Thomymaster]

Hi guys

I have my FreeNAS running with 4 HDDs and one SSD as ZIL device. When i try to configure a SMART test and include my SSD (ada0), then the SMART daemon stops working (see screenshot attached), when i remove the SSD it works again. When i manually try "smartctl -a /dev/ada0" i get my SMART data.

What is the problem here?

Cheers

Bet that when you run the test manually you don't have a TEMPERATURE value. this actually might be something worth looking into however I also realize you're new here but you need to provide the required minimum data so we can give you proper advice.

In order for us to help you with your question we will need the following information to the best of your ability. We do not like to make assumptions here as we might give wrong advice and the next thing you know, your data is gone forever. Please follow the forum rules so that we can offer proper assistance. Below is the rule #3. Provide as much information as possible and don't assume we know exactly how your system is configured.

Including the following information in your thread will increase the chance you will get an answer:

1. FreeNAS version and platform (32 or 64 bit).
2. General hardware information (CPU, RAM, Motherboard model, etc.).
3. Specific hardware information (Network card chipset, Raid controller chipset, etc.).
4. DMESG output or copy of specific error message.
5. IFCONFIG output if you are asking about a NIC or networking problem.
6. PCICONF -lv output if you are asking about MotherBoard and / or PCI card problems.
7. Code snippets, logs, config files and quotes should be enclosed in the appropriate bbcode tags.
8. To provide you with accurate answers we need this information and it will also help others to find your posts when they are searching for similar information.

Thanks for the quick response. First I'd tell you to remove the ZIL from your pool and then from your computer case. I have no idea what you are using this system for but your RAM is really too low and you need to bump it up to at least 6GB, but if you want great performance then just up to 16GB RAM as this allows high speed RAM to be the cache (LARC) and a ZIL just isn't really for most applications. This also goes for an L2ARC. I've done some testing and here is the link... http://forums.freenas.org/showthrea...Tek-NIC-Performance-Testing&p=58536#post58536 Don't let the name of the thread fool you, I have specific ZIL and L2ARC testing included.

I'm interested in the fact the SMART tests fail for the SSD. I'm sure FreeNAS has a bug which fails but I'd like to know more about how you are setting up the SMART test to be run for when you get the errors. Please assume I know nothing as it's the best way to give me all the information I might need to look into this.

Could you please post the results of the manual smartctl -a test for the SSD?

Bet that when you run the test manually you don't have a TEMPERATURE value.

If you notice joeschmuck was correct. Not sure how flexible the GUI is with this, but maybe create a seperate test for the SSD without checking for temperature if possible.

Nevermind. Looking closer it's exiting on (no Directive -d removeable). What does your smartd.conf look like:

Code:

cat /usr/local/etc/smartd.conf

 

[joeschmuck]

The FreeNAS system should still let a SMART Test be run so it looks like there is an error there. However again, the ZIL is likely not going to help you at all but if you leave it in, if the ZIL dies you will know it and you will not loose any data if it fails with a ZFS V28 formatted drive pool.

Hi

I now changed the SSD to be the L2ARC instead of ZIL which makes more sence with ISCSI. Here isa my output of smartd.conf:

Code:

/dev/ada4 -n never -W 20,50,60 -m ***@***.de -s S/(01|02|03|04|05|06|07|08|09|10|11|12)/../(3)/(13)
/dev/ada0 -n never -W 20,50,60 -m ***@***.de -s S/(01|02|03|04|05|06|07|08|09|10|11|12)/../(3)/(13)
/dev/ada2 -n never -W 20,50,60 -m ***@***.de -s S/(01|02|03|04|05|06|07|08|09|10|11|12)/../(3)/(13)
/dev/ada1 -n never -W 20,50,60 -m ***@***.de -s S/(01|02|03|04|05|06|07|08|09|10|11|12)/../(3)/(13)
/dev/ada3 -n never -W 20,50,60 -m ***@***.de -s S/(01|02|03|04|05|06|07|08|09|10|11|12)/../(3)/(13)

/dev/ada4 is the SSD

Cheers

Any news on this or is there something i can do?

 

[titan_rw]

If it's saying "unable to register device, no directive -d removable", I think that means it couldn't find the ssd at that time.

I'd be wondering exactly why, but you could try the following in "smart extra options" under "view disks - edit".

Code:

-a -W 0 -d removable

The -W 0 will get rid of the temperature warning. -a tells it to enable all the regular tests. The -d removable tell smart to run even if it can't open that particular device. Again, I'd be wondering why it can't open it at that time.

Also, why bother running self tests on an ssd? Do they actually do any good with flash media? Personally, I would disable them under "system - smart tests".

Hi

I upgraded to 9.2.0 and it seems that the problem has resolved.
