Hello,

 

I have a big problem. A few weeks ago i changed 4 Disks including the parity disk to bigger ones (all 10tb). 
 

Everything worked fine. Today I got a blackout and after the server got electricity again it wasn’t booting. The usb stick died, I wasn’t able to fix it in another system. It wasn’t recognized.

 

So I installed it fresh and picked an older config folder Finger my shares and other stuff back. But the backup seems to be older then the disk change xD.

 

now it says „wrong disk“ and I’m really afraid of losing my data.
 

can someone help me how to fix this?

 

 

Assuming all disks were enabled, you can do a new config (Tools - New config), keep all assignments and check "parity is already valid" before array start.

thanks!

 

Is there a way to see which of my 10TB Disks is the old parity disk? 

 

Is the wrong disk a data disk or parity? If it's not complaining about parity, that would be the parity disk, but if you are not sure, you can use this:

Yeah I habe 4 times wrong disk. But with the explanation in your link it should be fine 😊 

 

thank you
