Here are my previous posts about several of my disks throwing UDMA CRC errors, then actually disabling a disk. 

First post with issues

Second post with issues

 

I was doing an uncorrecting parity check to verify that my correcting parity check fixed the sync errors. 

I woke up today to find that my network connection to my server dropped. I logged in locally and there were a ton of warning popups. 

Now I have yet another disk that received UDMA CRC errors and is showing Errors on the main tab. 

The errors just kept coming, so I stopped the parity check. 

There's no way these are disk problems and I'm really doubting its related to the backplane in my case. 

Are we positive that it's not the LSI card?

 

I've been holding off on switching cases, to get rid of the backplane, until all the sync errors were corrected, but at this point I think I need to switch cases.

Is that a good idea? Just shutdown my server, remove everything, and put it all in my new case that doesn't have a backplane. So it would just be cabled straight from my LSI card and motherboard to the disks.

I can't afford to keep getting disk errors and I have too much stuff going on in my life to deal with this. 

 

I'm at a loss and confused.

Just wondering what you all would do in this situation.

I grabbed all this information before I shutdown the server, because I don't want it running at this point.

It can be, it could even be neither, it could be for example a PSU problem, but since there are also CRC errors and those can basically only be from the controller, cables or backplane and the other disk issues are likely related it should be one of them, backplane more likely but HBA is also a possibility, especially if it's a Chinese fake, unfortunately no way of knowing for sure until you rule one of them out, either by using a different HBA or connecting the disks directly bypassing the backplane (or using a different one).

Thanks for responding to all of my problems. I really appreciate it. 

 

So moving my server into the new case without the backplane should be my first step?

It's what I would do, unless you have another HBA you can try with.

Thanks. 

I'll switch cases and report back. It might be a week or two before I have time for that. 

Status update:

 

Just because I had my server down and because I don't have time to move it to a new case, I ran memtest+86 for over two days.

It did 7 passes with no errors. 

So at least I confirmed my memory is good.
