ReadyNAS Ultra 4 - The array is still in degraded mode

Hello just added two new 4 TB drive to my Ultra4; first drive loaded and sync correctly however after installing, test and sync the 2nd I'm now in Unprotected mode with the following messge:

"RAID sync finished on volume C. The array is still in degraded mode, however. This can be caused by a disk sync failure or failed disks in a multi-parity disk array."

 

Current config is as follows

Ch 1 : WDC WD40EFRX-68N32N0 [3726 GB] 3721 GB allocated (disk failured)
Ch 2 : WDC WD40EFRX-68N32N0 [3726 GB] 3721 GB allocated
Ch 3 : WDC WD30EFRX-68EUZN0 [2794 GB] 2790 GB allocated
Ch 4 : WDC WD30EFRX-68EUZN0 [2794 GB] 2790 GB allocated

 

I've removed the failed drive formated it and scanned it for any faults, everything came back clean; tried installing it again to the same result.

 

I can provide logs to anyone who needs them. I'd appreciate any help that you could provide.

It looks like the problem is with md2 (and that you started off with a 4x1 TB array).

 

You could try

  • removing the disk
  • power down the NAS
  • disconnect from the power main for a few minutes (maybe 15)
  • reboot the NAS
  • reinsert the disk.

Part of the rationale here is to clear out any bios state associated with the disk.  Sometime the NAS drivers will declare a SATA bay down, and this should make sure it's up again.

Re: ReadyNAS Ultra 4 - The array is still in degraded mode

What RAID mode are you running?

 

One thing you can try - connect the disk to a Windows PC and test it with WD's lifeguard program.  Use the "advanced" write zeros test this time - it sometimes picks up issues that the non-destructive test misses.

 

Also, have you looked at the smart statistics in the logs?

Re: ReadyNAS Ultra 4 - The array is still in degraded mode

Hi StephenB


Raid Mode: RAID Level X-RAID2, 4 disks

Smart status: says Dead

When I tested the drive orginially I used AOMEI partition assistant from: https://www.disk-partition.com/ and used the quick scan

Then I suggest retesting with Lifeguard.  Do the long non-destructive test first - if it passes, move on to the full write-zeros test.  I suspect one of those two tests will fail.

You are likely looking at the web ui.  You should see a lot more in disk_smart.log (in the log zip).  That would include reallocated and current pending sectors, uncorrectable errors, crc error counts, etc.

Re: ReadyNAS Ultra 4 - The array is still in degraded mode

Can you post again, showing the "RAW_VALUE" field at the end.

 

FWIW, you can also copy/paste the stats for disk 1 into your reply.  Click on the "insert code" tool and then paste the stats into the pop-up.

Re: ReadyNAS Ultra 4 - The array is still in degraded mode

Thx.  So this drive doesn't have any SMART errors logged.  Perhaps check the other disks for errors (looking at the RAW_VALUE field).

 

Can you also post mdstat.log?

It looks like the problem is with md2 (and that you started off with a 4x1 TB array).

 

You could try

  • removing the disk
  • power down the NAS
  • disconnect from the power main for a few minutes (maybe 15)
  • reboot the NAS
  • reinsert the disk.

Part of the rationale here is to clear out any bios state associated with the disk.  Sometime the NAS drivers will declare a SATA bay down, and this should make sure it's up again.

Re: ReadyNAS Ultra 4 - The array is still in degraded mode

It doesn't look like a dead bay issue, because all the other partitions of Drive 1 (sda) are included in their appropriate RAID groups.

 

I think you are going to find a bad sector on the drive.  But why it wouldn't just re-allocate it and go on is a mystery.

 

If it still doesn't sync after you've done all @StephenB has advised, I can give you SSH command for it to re-try adding the partition to the RAID.  But it's probably unlikely that would be any more successful.

It doesn't look like a dead bay issue, because all the other partitions of Drive 1 (sda) are included in their appropriate RAID groups.

It didn't seem that likely to me either.  But in the first post he said the drive was identified in web ui as dead - and it wasn't clear as to why.  So I suggested the longer procedure.
