Drive faulted due to errors, next steps?

[jnyl42]

My (fairly new) 10 disk RaidZ2 just disabled a drive due to persistent errors (6 read errors, 69 write errors according to volume status). This is the first time I've had this issue after putting the system to use. What are my next steps?

- Can I do some diagnoses to make sure it's the disk going bad, and not just a cable or something? It's a relatively new build, ~ 4 months old.

- Should I go ahead and order/buy a replacement disk? Will I have compatibility issues if I change the WD Red with an HGST Deskstar NAS?

Any other considerations?

Thanks for the help. The user manual only says how to replace the disk.

I would first check the sata and power cables. U don't have pending or offline sectors either, so of it was me, i would keep an eye on that disk but wait before replacing.
In any case wait someone else suggestion to decide.

 

[Bidule0hm]

I agree ;)

 

[Ericloewe]

CRC errors are characteristic of cable issues. Make sure all SATA connections are less than 1m in length.

 

[jnyl42]

Damn. I rebooted to put the drive back online, had some checksum errors but seemed to be ok... but it just faulted and degraded the volume again.

CRC errors are characteristic of cable issues. Make sure all SATA connections are less than 1m in length.

It's a 2ft SAS to SATA breakout cable... but it's some no-name brand. I could try replacing it but I have no idea where to find a good one.

Is it possible to switch the drive to a different SATA port?

 

[gpsguy]

Sure. FreeNAS uses gptid's and it doesn't matter which physical port you plug the drive into.

Is it possible to switch the drive to a different SATA port?

 

[jnyl42]

Thanks for all the help. I tried 3 different SATA cables on different ports, but it never made it more than 30 minutes before the disk would go offline again. I went ahead and replaced the disk. WDs have a nice warranty so I'll get it serviced and keep it as a spare.

@jnyl42

Your power cycle count is 203 while your start stop count was 989. So either your disk is having to spin down and up because of errors or you are putting your disk to sleep.

*IF* you are putting your disk to sleep, it is possible that the disk isn't waking up in time before ZFS times out and fails the drive. This is one of many reasons why I don't recommend sleeping disks.

Just something to think about...

 

[jnyl42]

By putting the disk to sleep, you mean the setting "HDD Standby"? In that setting, all my disks are set to "Always On"

Just checked a good disk, and the power cycle and start-stop counts match perfectly, so I don't think they're sleeping

Appreciate your input though as always CJ :)

 

[cyberjock]

That is what I mean. You can also change the APM value as some drives will spin-down based on that number.

Yeah, just replace the disk. It's clearly not doing well.
