Hardware failure - need help

[cpotter638]

Built a FreeNAS box 4 years ago for our home. Has been running trouble free, that is until now.

I had essentially no trouble building the system, but have never had to troubleshoot.

Yesterday, received the following error:


Checking status of zfs pools:
pool: Volume1
state: ONLINE
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.

I logged onto FreeNAS GUI, and when viewing my 6 disc, the 6th disk had a blank name and an unknown serial number.

Just in case, I backed up the config file. Out of curiosity, I rebooted the system. System boot hung and box itself started beeping. I did a cold reboot and got box to boot. I then received a critical alert stating that my volume is DEGRADED.

I again went to GUI and when looking at zpool status, 5 disks are online. The other is unavailable.

Build details:
Build:

• OS: Thought I was using FreeNAS 8.0.2. But GUI says FreeNAS-8.0.4-RELEASE-x64 (10351)
• Case: Norco RPC-4220
• PSU: Seasonic M12II
• MOBO: Supermicro X9SCM-F with IPMI
• CPU: Intel Xeon E3-1220
• RAM: Crucial 8Gb ECC DDR3
• USB: Patriot Xporter 4Gb
• HD: 6x Seagate 2.0Tb Barracuda Green

Questions:
Anything else I need to do to diagnose? I assume I have a disk failure? If so, how do I determine which of the 6 drives has failed?

Thanks in advance for the help.

Pretty much what happened to me a few weeks ago. You can consider this drive dead.

You can use glabel status and smartctl -i or one of my script to identify the drive (look at the link "Useful Scripts" in my signature) ;)

NB: if the drive is as bad as I think it is then you'll not be able to identify the drive so you'll need to identify all the other drives and unplug the one you can't identify.

I found the bad drive. Questions:

All I need to do is remove bad drive and install new drive? Zpool will be automatically rebuilt with new drive?

When purchasing new drive, I assume I need to match the size of all other drives (2 TB)?

Thanks again.

The manual has click by click instructions for replacing a failed disk. Follow them. DO NOT under any circumstances use the Volume Manager. You'll need a disk at least as large as the smallest disk in your vdev, but it can be larger.

Surprised no one gave him a hassle for being so many years behind in his FreeNAS version?

It's not some weird software issue, so no reason to urgently mess with it, IMHO.

These things should be behind firewalls anyway, so security isn't critical.
