rsam Posted February 12, 2020 Share Posted February 12, 2020 Hello folks, I have been moving things around on the unraid server over the last few days, rearranging my data on disks using gather on unbalance with the goal to remove my 2 2TB drives to my backup. everything was going great until this morning I got an email from the server indicating one of my drives has read errors. It is one of my parity drives. I ran the SMART extended self-test and it completed without errors. I don't understand everything in the SMART reports but from what I have gathered the following indicates the drive is still good? 5 Reallocated_Sector_Ct PO--CK 100 100 005 - 0 196 Reallocated_Event_Count -O--CK 100 100 000 - 0 197 Current_Pending_Sector -O---K 100 100 000 - 0 I could be wrong. I have posted my diagnostics (tools -> diagnostics), hoping someone could take a look and let me know if the drive is toast, or what else could be causing the problem. For now I am going to shut the server down and try changing the cable... Thanks in advance. Rick thevault-diagnostics-20200211-2228.zip Quote Link to comment
rsam Posted February 12, 2020 Author Share Posted February 12, 2020 I shut the server down and check/reseated all the cables. Started it up (took longer to boot up than it usually does). There are no more read errors but the drive is still disabled. Not sure what to check now. Quote Link to comment
JorgeB Posted February 12, 2020 Share Posted February 12, 2020 Disk looks fine, replace/swap cables just to rule them out and re-sync parity. Quote Link to comment

Thanks Johnnie for the response. Last night I swapped the cable and no longer were there any read errors, but the drive was still disabled and I couldn’t see how to enable it. Well preforming a parity sync allow me to enable to drive? Or is this something else I have to do to enable it first? thanks Quote Link to comment

rsam Posted February 12, 2020 Author Share Posted February 12, 2020 Thanks, I should have checked there first :). I will follow those steps tonight. Thanks again Rick Quote Link to comment
rsam Posted February 13, 2020 Author Share Posted February 13, 2020 SO I followed those steps as listed in the WIKI and it worked, the drive is back on line with no errors. Actually I decided to kill two birds with one stone, since I had to run a parity sync, and decided to remove the 2 2TB drives at the same time and do a new config. About 12 hrs later it was done and so far so good. Next, I will be upgrading to a larger CACHE drive and then a second one for redundancy...fingers crossed... Thanks again Johnnie for your help...
