Yesterday my NAS (called NASA) suddenly sent me an Alert about Parity Disk 1 beeing in error State.
Ich checked Parity three days before with 0 Errors.

I downloaded the Diagnostics and startet a big SMART-Test after that.

 

The Paritydisk is only a few month old and the whole system is normaly shut down when not in use.

 

Do you need any more information then the above?

 

Dont know what to do next. :(

Hope you can help.

 

Thanks Miles

Ok, I knew that I would have forgotten something.

 

The two Paritydrives are connected via a 4 * SATA <-> SAS cable to the HBA. Three weeks ago I added two used SSD cache drives and these are also connected over the same SATA <-> SAS cable. Might this have caused the problem?

 

I now disconnected one of the SSD (wich I didnt use anyway) and connectet the failed Paritydrive via SATA directly to the motherboard.
So on the SATA <-> SAS cable remain the SSD Cache Drive and the Parity 2.

No.

That's good to rule out any other issue, so if the same disk fails again it's probably bad.

Ok, I started parity rebuild right now.

 

Will come back to you when finished.

 

Thank you very much for your help!

I really appreciate it.

 

Miles

 

P.S.: I will flag it as SOLVED after rebuild shows now problems.
