[SOLVED] Cannot resolve Stale Configuration error

Hi all,


For the past 3-4 months whenever I restart my server I get a "Stale Configuration" at the bottom left of my screen and all array drives are unassigned. Pool drives retain their configuration.  I re-assign the drives and the array starts just fine. The problem is a Parity-Check in my case takes almost 48 hours, not to mention the extra strain it puts on the drives. 


I've read all forum posts on the subject, and tried every possible combination of creating a new config and re-ckecking parity I could think of, but to no avail.


Can somebody show me the correct procedure to get rid of this problem?


Thanks in advance,




PS : Please find attached my diagnostics zip.

There's problem reading super.dat, that's where the disks assignments are stored:


Jun  6 13:57:59 Thales kernel: kernel read not supported for file /config/super.dat (pid: 14582 comm: modprobe)
Jun  6 13:57:59 Thales kernel: read_file: read error 22
Jun  6 13:57:59 Thales kernel: md: could not read superblock from /boot/config/super.dat
Jun  6 13:57:59 Thales kernel: md: initializing superblock


Try recreating the flash drive, if that fails use a different one.

Hi Jorge,


I've tried both recreating the old one and using a brand new flash drive but I keep getting the same error at startup (Stale Configuration) and all array disks show as unassigned.

Attached you will find my diagnostics after I replaced the flash drive and restarted a couple of times.


In  a separate, but possibly related issues, my server has been acting up lately and at random intervals it hangs unexpectedly, usually during the night. I mean IPMI shows the server as running but the server is completely unresponsive to web gui, ssh, smb etc.


Any help would be greatly appreciated.

Other than that I'm not seeing anything out of the ordinary, can you try without the Nvidia driver? One of just two google results I found about that error mentioned an issue with that.

It's starting to drive me crazy !

Stopped the array, removed nVidia driver, rebooted the server - Stale Config .... Created new config, without keeping any assignments, re-assigned all drives, restarted the array choosing 'parity is correct'. Rebooted the server - Stale Config again !!!


Attaching new diagnostics for whatever it's worh ....

Stale config happens when there is a mismatch between the super.dat and super.old configuration files.

Take the USB drive out and run a file check on a Windows machine to see if there is any file corruption and repair as needed.

Just did the file check. No errors found, as per the attached screenshot.


It is a brand new USB (Samsung Bar Plus 32 GB) which I created using the Unraid tool, from a flash backup I took just before I shut down the server to replace it.

Normally super.dat is created as soon as you make a (new) array assignment.


You can delete all super.* files and restart the system.

It requires you to do a new array assignment. When done and the array is started, check the presence of both super.dat and super.old

Thank you for your help.

I followed your suggestions (deleted both super.* from /config) and then restarted. After startup I created a new config from the Tools menu, and reassigned all drives. Then I started the array again, selecting "Parity is valid" option. I checked and found that super.dat was recreated in the /config folder of the USB Flash.


I will restart the server again to see what happens and let you know...

Thanks a lot for all your guys help. Really appreciate it.





PS : How can I add SOLVED to the topic ?

Don't understand how redoing the flash drive didn't help and this did, but hey, glad it's solved.

You can just edit the title, but I can do it this time.
