Disk 5 continuous issues UnRAID 6.11.0

[muntedewok]

Hi guys,

 

Have an issue with Disk5 on this array. It'd been working flawlessly for years, replacing a drive every once in a while. Recently Disk5 has been dropping and I've been replacing it with known good drives. Some will rebuild OK and others won't, it'll start then fail for no reason however the SMART data appears fine. I thought this might be a cabling issue so I've used many different data and power cables for the drive(s) being used for that slot, to no avail. Today I decided stuff it and went and bought 2x 3TB WD drives (1 as a spare) however now I'm having EXACTLY THE SAME issue with these drives and it's doing my head in.

 

Not sure what's happening, next I might need to start considering the SATA RAID controller is on the fritz?

 

Diagnostic logs attached.

 

I suspect there MAY be an issue with Disk4 which is causing issues with the rebuild as well though haven't been able to confirm. I'm not particularly worried if I drop Disk4 but it's read/writable so I can move the data off this drive onto another for the time being......

 

Any help or insights greatly appreciated.

It's logged as a disk problem, connect that disk to the onboard SATA using different cables and try again.

Hi JorgeB, which disk is logged as the problem? Disk4 or Disk5?

 

I might add I previously had various drives in the position of "Disk5" connected to either motherboard or SATA RAID controller on various SATA breakout leads.

 

Cheers,

Unfortunately same issue with new SATA cable plugged directly into motherboard / different SATA power cable as well

Disk dropped offline again, did you also use a different power cable?

Then it suggests a bad disk.

[muntedewok]

Same outcome for at least 5 drives now? Drives are all passing SMART tests, no disk errors. Drives never stops spinning, you just watch the transfer rate creep down for no reason then suddenly there's errors and the drive drops out of the configuration.

If new cables and different controller don't help there are not many other options, I assume it's not using a slot in a backplane? PSU is a possibility, but it doesn't make much sense that it's always the same disk failing.

Don't believe it's the miniSAS RAID card fault as the issue still happens even with drive connected directly to motherboard. Going to have to start considering either motherboard or PSU issues overall and swap them out. Hell, I've even switched SATA cables from working drives to the replacement drive slot with same issue.

 

Before I begin tearing it down though looking for issues, do you think it'd be worthwhile creating a new configuration first and importing all the drives back in?

[JorgeB]

You can try but unlikely to help, and if it does it will probably be a coincidence.

Decided stuff it. Pulled the drives and SATA RAID card out of the existing platform and stuffed it into a spare ML110 G8 I had sitting around collecting dust, tested USB key first, booted no issues, installed drives (using built in backplane controller as well as SATA RAID card w/ SATA breakout cables), existing drive configuration OK, installed "troublesome" Disk5 (the 3TB WD Red from last few diagnostic runs) and rebuilt correctly. Putting this down to either faulty motherboard or PSU however not going to bother trying to diagnose that issue..... suspect one or the other but both are getting on a bit.
