Good day to you all. So i have recently upgraded my parity disk to an 8TB wd red. I took my old parity disk, cleared it and added it to the array (6tb wd red). everything went fine but now it shows as unhealthy. 

 

I am asking for help because i don't know much about this part to tell if it can be saved or if it needs replacement.

 

Thank you all in advance for your support.

SMART attributes look fine, there are some UDMA CRC errors but that is a connection issue, usually the SATA cable, there are also some recent UNC @ LBA errors, but the extended test passed, so it's fine, at least for now, you can acknowledge the CRC errors.

Hello tee-tee jorge,

 

Thank you for your fast reply and information. I will swap the cable out shortly. Do i need to rerun the test after the cable is changed?

No, you just need to monitor the UDMA_CRC attribute, if it keeps increasing there's still a problem, but note that it will never go back to 0, you can just acknowledge current value.
