Hi all, I have a setup with 4 Disks  + 2 Parity Disks + 1 cache.

 

I keep having errors in the parity disks. Sometimes parity builds and stays for some hours/days, but I keep getting errors.

 

SMART looks ok for the disks, I even have 2 spare disks and get the same errors.

 

Can you please help me?

 

I changed already the LBA card for a new one, changed mini SAS cables, etc. Thank you.

This usually means a power/connection problem, and it's happening for multiple devices, see if they share something, besides the miniSAS cable, like a power splitter.

Hi @JorgeB,

 

thank you for the information. I have 2 different power splitters for all the HDDs, from the same PSU... I have a spare PSU that I can swap to try it, will update this issue in about 2 days.

Hi @JorgeB, after a few days of uptime and no errors, this was the problem. I changed the PSU and everything is working fine. Thank you very much for the support.
