September 4, 20178 yr I am a good monkey and followed directions. Unraid 6.3.1 I run automatic monthly parity checks (1st of month) I haven't rebooted or touched anything and came here first before I proceed. I have attached zip file as "readme" instructed. I am a noob. Questions: 1) What is problem? 2) Did I lose data? 3) How and what to do to fix anything? 4) Other than monthly parity checks is there anything else I should do as preventative measures? I appreciate assistance, happy holiday deathstar-diagnostics-20170904-0730.zip
September 4, 20178 yr Community Expert SMART for parity shows a pending sector, so likely a disk issue, you can confirm by doing an extended SMART test.

Tried extended SMART test and where it says "Last SMART test result: Errors occurred - check SMART report". It took about 10 seconds for that to show up and couldn't finish past the 10% mark on the SMART test. Tried it multiple times and anywhere from 7-10 seconds just came back to "Errors occurred" message. I added another diagnostics report after attempting to run extended SMART report but I don't believe it did anything? You guys are experts so I have no idea. If it is bad parity drive...guess I can go shopping for new drive? If that is the case I was thinking of upgrading total size of disk from 2TB to 4TB. If I understand correctly I could replace the 2TB parity drive with a 4TB drive and have no benefit until one of my data drives is upgraded from 2TB to 4TB, yes? So to see benefit I would have to get (2) 4TB drives...1 for parity and 1 to upgrade size of 1 of the data drives? As time goes on 1 by 1 I could upgrade my 2TB drives to 4TB drives as they get old and fail, correct? What are my next steps? Thank you for assistance deathstar-diagnostics-20170904-1406.zip
September 4, 20178 yr Community Expert SMART test failed with a read failure, disk has bad sectors, I recommend replacing it, you can also try to re-sync parity to see if the bad sectors are remapped, but even if they are there could be more soon, up to you.
September 4, 20178 yr Author Understood....time for new replacement parity drive. Am I correct in my understanding of upgrading from 2TB to 4TB drives? Thank you for help
