READ/WRITE ERRORS WHEN RUNNING PARITY CHECK

[megaz221]

I keep having issues with read/write errors on certain disks and it seems to occur during parity checks most of the time. I was getting some UDMA CRC errors on a couple of disks but it doesn't seem to have occurred in a while and not sure if it's related.

 

Disk 3 in specific seems to keep getting disabled even though SMART data looks fine other than the UDMA CRC errors. It does have about 5 years of power on time but other than that I don't see anything out of the ordinary. 

 

Disk 1 is the oldest of the array with over 5 years power on time, but has a ton of UDMA CRC errors. I'm not sure where these errors come from, I've checked cable connections and everything seems fine.

 

I have also connected the server to UPS to prevent any unclean shutdowns during a power outage, I've had a couple instances of the server shutting down uncleanly during power outages.

 

I have attached diagnostics for reference. I'm also runnnig an extended SMART test on it as we speak and it's about 50% done.

 

And yes, I'm aware the disks are very full. I've ordered two 14TB drives to add to the array but not sure if I'm just going to have to replace disk 1 and 3 (i would rather not assuming there is no actual issue).

 

 

And just for more info, I'm running unRaid as a VM in ESXi, passing through two LSI controllers that have all of the disks attached.

 

 

I posted a thread in support where the mod mentioned virtualizied unraid was unsupported. I'm just hoping someone can review the diag and let me know if there is an issue i'm missing.
