My Unraid Version is 6.12.11

 

I'm having an issue where my server will be working fine but then I'll randomly get an error notification saying a disk in my array is having read errors. When this happens, I'll stop the array and the configuration will tell me I have a drive missing. Only when I reboot will all the drives appear to be there. Then after a while, be it 10 minutes of several hours, it will have read errors again then rinse and repeat. Sometimes I have to open my server and fiddle with the cords before the drive shows up again. It's done this with both Disk 1 and Disk 3. Although after gutting my computer and replacing all the SATA cables, it seems to be only disk 1 now. It should be noted that none of these drives were in an error state. They are simply having random read errors that sometimes cause my shares to disappear until a reboot.

 

A few days prior to this, my Parity drive was in an error state and making odd noises so I removed it from the array and attempted to preclear it but it failed during the pre-read step. I assumed it failed mechanically but then I moved the drive to my personal desktop and it is curently being zeroed out and formatting just fine so far so who knows if the drive was actually bad. Right now I feel like I can't trust SMART because of how weird the situation is.

 

As of right now, my server is unprotected due to the lack of a parity drive and this read error situation has me stressing out that I might lose 4 - 8 TB of data. All of my drives currently have a Healthy SMART status but there is an extended self-test running on Disk 1 currently just to be safe. I have also attempted a read check on my array which runs fine until the read errors how up again and the errors flood in.

 

I have also started the Array in Maintenance mode and done a file system check which always comes out fine.
 

At this point, I'm ready to chalk all of this up to my SATA slots or entire motherboard being defective but figured I'd see if my diagnostics reveal anything peculiar. It should also be noted that I am using a PCIe 4xSata slot expansion card in addition to my other SATA slots on my motherboard.

 

In short, I feel like my server is gaslighting me something fierce and any input would be greatly appreciated. Thank you in advance!

Added syslog

Looks more like a power/connection issue, could also be the controller since it's Marvel, disk1 is also using it, were the issues only with those two disks?

Thank you for your reply!
So far, yes it's just those two disks. There was also a time when I removed all my drives from the controller and used just the SATA ports directly on the mother board and I still got the read issues, of course that was before i removed the parity drive that was going haywire. Whenever the read issues seem to happen, the sys log says disk 3 is having read errors but when I take the array offline, it's disk 1 that appears to be missing. As of right now, the disks have appeared to have lasted the night without any read errors, I'll attach an updated diagnostic just in case.

I spoke too soon...I have no notifications of read errors but Disk 3's file system seems to not be present now. From the Dashboard everything appears normal but DIsk 3's files are gone as well as some of my shares.

I am so confused, if it actually did disconnect, why did everything appear fine on the dashboard and the SMART status still healthy? And why were there no notifications of this happening?

Anyways, disk 3 seems to be the sole issue now but the problem was definitely present with disk 1 at some point so it may very well be where it was plugged in to the motherboard. Going to try again removing all drives from the controller and just use the SATA ports directly on the motherboard.

I started it back up with them only connected to the motherboard SATA ports and it immediately started having errors again.

Any power splitters in use? But the disks could be going bad.

I do have a power splitter that splits 1 connector into 4. I removed that splitter and used just the base connectors that came with the power supply (since my parity drive is out there are enough now). I've booted it back up and no errors so far...The SATA cables are in the same spot as before. What would you suggest to know for certain whether the drive is bad? A SMART extended self-scan? A read test? Or any other suggestion you have?

Avoid these like the plague, if you need splitters, use max 1 into 2.

This is a good test.

 

Cool, I'll run a read test. if it completes fine, I'll just mark this as solved. Thank you!

Beautiful. Thanks again!
