Hi all.

Sunny greetings.

 

So, replaced my disk 12 from a 4TB to a 18TB.

Disk started rebuilding, but started getting errors on Disk 1, 4, 6 & 9

No indication of errors beforehand.

 

I rebooted and it's doing a Data-rebuild again.

 

Just wanted to check with the community what you suggest I should do next?

 

New cables and a beefy power supply in the server.

Disk 1, 4 & 6 are all relativyly new SG Exos drives so 

Disk 1 - new Exos

Disk 4 - new Exos

Disk 6 - new Exos

Other disks are a mixure of of SG/Toshiba drives.

 

Your comments, sugestions will be appriciated.

 

Many thanks,

Al

Looks like a power/connection problem.

IS the PS new also?  (It is not unknown for a new power supply to be bad...)  

 

Were the cables replaced when you upgrade disk 12?

 

@JorgeB is correct, working inside a case when replacing a Disk Drive, it not uncommon to loosen other SATA connectors-- both data and power.  Reseat all of them and  double check them again!

 

 

Not long rebooted and now only 1 x disk is showing errors! - straaaange.

 

I will re-check the cables (which are 3 x months old).
I will also check the power supply - (3 x years old), so could be the PSU.

The PSU has modular cables so I will try a new cable on the PSU and see what that does.

 

Thanks again.

One thing to be aware of is that cables are often not interchangeable between different modular PSU, and if you use an incompatible cables you can damage the electronics on a disk drive.

Solved: Cables checked and all working fine now (parity build at 20% and going strong with no errors)
