Is this a drive failing?

[KempelofDoom]

I get these emails now with the following.

freenas.CRASH_SVR kernel log messages:
> ahcich8: Timeout on slot 13 port 0

I have a disk to replace ada7 but when I follow the guide to replacing a disk I don't have any of the buttons to begin the process. Is the above an indication of a drive failure? It passes scrubs with no errors. I get those messages daily now. Is there a command line guide for drive replacement?

How about starting by adding your FreeNAS version and hardware specs as the forum rules state?
Did you configure regular SMART tests?

Then you should poll the SMART information for the drive with smartctl -a -q noserial /dev/ada7 and see if there are indicators of a failing drive. Furthermore dmesg may give you more information about the error.

The load cycle count of this drive is extremely high (839,516). These drives are usually rated for 300,000-500,000 cycles in their total life time - and your drive is just about a year old. This is a known issue on WD Greens (2 and 3 TB), my build is facing the same problems. You should read this article for more information: Hacking WD Greens(and Reds) with WDIDLE3.exe

The rest of the SMART values look OK. Is the drive connected directly to the mainboard or do you use a separate controller? Which mainboard are you using?

EDIT: This drive never performed a SMART test. You should probably configure automatic smart tests, see the FreeNAS manual for details. It wouldn't hurt to run a short test to see the results.

Sorry for the double post. Missing buttons in the GUI have been an issue for touchscreen devices and certain browser in the past (for example see Bug #4486 and Bug #4130). You might want to check with another browser and/or upgrade to the latest FreeNAS version although I don't think any GUI related changes went into 9.2.1.4 and 9.2.1.5.

Correctly replacing the drive from the command line is a bit tricky, since FreeNAS expects certain things like a GPT partition for the ZFS to reside in and a swap partition, both which are created correctly when using the GUI.

Total noob here but I just figured out what I was doing wrong. I was looking for a volume status button but didn't realize the button that looked like a sheet of paper was the view status button till now. Once I clicked on that, I was able to see the disks and can now do the offline and replace process. Man do I feel dumb.

We're all just human ;)

If you are replacing the disk with a new WD Green, keep in mind to use wdidle3 on it before (or after) like explained in the other thread. If you have other WD Greens in your pool now, this would be important to do as well or you might see more drives failing shortly.
