(solved again) Array has 5 disks with read errors.

Featured Replies

As the title says.

Screen shot shows the discs, diagnostics logs included.

Also:

Wen using crusader i cannot access disk 3.

/mnt/disk 3

is somehow a file of zero bytes and not a folder

I put Unraid in maintenance mode and ran a short smart test on Disk 3 it completed with no errors.

Edit: i added the SMART diagnostics of all  5 disks with errors after running short SMART on all of them. Disk numbers appended( Disk 1 etc).

Disk 3 is also running the extensive SMART check atm.

What should i do ?

How bad is this?

Don't see any controller issues logged, so most likely a power/connection problem, power down the server, check all connections and power back up, array should be accessible after that.

Thank you for your response.

I have rebooted, Unraid then reported zero errors. Then i started the array in maintenance mode, now doing a Parity check (read only).

After that ill try starting the array normally.

Oke it got worse i finished the Parity check with no errors and then tried to start the array normally now i have 6 unmountable Disks.

That is every Data Disk except Disk 5...

Edit: i included new diagnostics

Same Issues I'm having. Are these shucked drives?

Edited by TechTitus

Yes they are, but the Disks them selves are fine according to SMART. This happened after upgrading to 6.9.2 and then downgrading again to 6.8.3. So i am hoping that it is just some limited file inconsistency. And not a mayor failure of hard drives or the whole array.

Yep, I'm having the exact same issue and UDMA CRC errors as well. I'm going to swap Power Supplies to see if it's a power issue.

This is a likely a power, connection or controller problem.

This is a likely a power, connection or controller problem.

But this issue happened after downgrading from 6.92 back to 6.83 nothing else changed. I also read that some people had compatibility issues with the newer version.

I use a:

https://www.broadcom.com/products/storage/host-bus-adapters/sas-9300-8i

What can i do to fix this?  I understand that it is hypothetically possible that my power supply failed  or that it is a cable failure but it seems incredibly unlikely to me that this happens at the exact time that that i run into OS issues due to updating and downgrading my OS version.

Edit: oke i disconnected and reconnected the HBA and my array is back so maybe it was a badly plugged in connect?

It's still a hardware issue.

How should i handle the 22 errors that 6 Disks are reporting?

Well the errors are back again now on Disk 6 and 7.

Still looks like a power/connection issue.

Shutdown server, re plugged HBA and all Disks. Then started it up again.

After some time new errors

The weird thing that stands out to me is that the errors occur after the 2 disk happen to spin down. Could that be related?

Also if it is a hardware defect....I don't have a spare HBA, proper size power supply or SAS cable to do any testing (by swapping them out ) so i am at a loss as to how i should handle this right now.

Is there anything i can do?

It could, though don't remember spinning issues with WDs, but try disabling spin down to see if it changes anything.

After disabling spin down on all disks and restarting the server it has now been running for 1d and 3 hours without any errors, so i am assuming it is fixed.
