Parity check takes 153 days or more! Disks spin down while copying data.

[Alban]

My Unraid doesn't work anymore.

The parity check will take more than 150 days.

When I try to copy larger amounts of data, it will at some point spin down all disk and the copying will stop.

I searched the forum here for both problems but didn't find anything that seems to apply to me.

What can I do?

Attach Diagnostics to your NEXT post in this thread

Thanks! Here are the Diagnostics.

The diagnostics seem to be just after booting.    It would be useful to have some taken when you are experiencing the problems you describe.

Ok, so this is the diagnostics when performing the parity check. It was at about 54 days duration.

You are getting lots of read errors on disk7 in the syslog and its SMART data shows that it has 1962 reallocated sectors, and a Failing NOW status.  
 

I have not checked the SMART data of the other drives to see if any of them might have issues.

Thank you! So this could be the reason for the slow behaviour? So I should replace disk7? Can you point me to the docs how to actually replace a disk? When I tried to replace a disk before it was just addes as a new disk to the array. I am quite the beginner with Unraid...

Almost certainly.

Replacing disks is covered here in the online documentation accessible via the ‘Manual’ link at the bottom of the GUI or the DOCS link at the top of each forum page.

It also has 34 pending. And disk9 has 8 pending sectors.

 

If you look on your Dashboard page, Unraid is showing you the disks that have problems ( 👎 ), disk7 is the most serious, but disk9 could give problems trying to rebuild disk7.

 

Do you have Notifications configured to alert you immediately by email or other agent as soon as a problem is detected? Don't let one problem become multiple problems and data loss.

 

Several of your disks are very old. All disks must be working well to allow you to rebuild a failed disk. Parity by itself can rebuild nothing.

 

Do you have backups of anything important and irreplaceable?

Thank you very much! Replacing disk 7 did help! I will replace disk 9 shortly.

I do have backups of the most important data.
