I have been fighting Unraid drive errors since I bought the product last winter.  I thought I had replaced enough to stabilize everything as the errors went away for nearly 8 months, but then last month I ended up with 2048 errors.  The problem came back a month later during the parity check after replacing a drive.  

 

I don't think my drives are bad at this point.  Can someone help guide me on how to troubleshoot this?  

 

In the past I've replaced my LSI card, the drives and the squid cables.

It's not logged as a disk problem and SMART looks OK, I would start by updating the LSI firmware to latest, since that one is a little old, could also be a power/connection issue, also I seem to remember some issues with older SAS2 LSI controllers and high capacity Seagate drives, but see if the firmware helps.

I could have swore I did that already.  I bet I did it on the old card. 

 

I ran flash updates against this card, thanks for the awesome instructions.  

 

I'm rebuilding the data on the errored drive now.  There isn't a better way correct?  You have to rebuild after a "drive error event"?

 

Well that's not good.  This is after starting the array rebuild.

Why didn't you ask for advice before now? Connection problems are much more common than drive problems.

Attach NEW diagnostics to your NEXT post in this thread.

I was being guided by a friend of mine that is more versed in Unraid than I.  

 

I stopped the data rebuild for now.  I'm awaiting your guidance.  Thank you.

Similar to the previous issue, not that I really suspect the LSI but since you have unused onboard SATA ports I would connect all the disks there and retry to rule that out, if issues persist PSU/power connections would be the next suspects.

So I drove in and bought another power supply since this is my second LSI card and set of cables.  I then thought about how I had it set up, I had 4 drives powered off of one sata power cable (1 to 4 split).   Just for giggles I moved one of the drives to share a power cable from the fan controller, then powered it on and started the process again.  So far so good...

 

Digging around I found that each cable shouldn't support more than 3 drives at a time.  Do you guys have any rule of thumb?

If this is the PSU cable with 4 SATA plugs it's not a problem, if you are splitting 1 SATA port into 4 it can be, it should not be split into more than 2 disks.
