Hi,

 

I have installed a SATA expansion card into my server and have put the hard drives into hot swap caddies.  Stupidly, I have added two new drives to the configuration at the same time. These two drives used to be in the server before I removed them, what I didn't do was to reformat them before putting them in.  

 

When I booted up and had the two new drives assigned, the system showed the system to be all ok (all green icons) which threw me as I wasn't expecting that.  So, I went to remove the two new disks, however, it now shows them as missing rather than just forgetting them (which I'd rather). If I try and drop one at a time, I don't know what to do because the parity shows as new.

 

I definitely have the same drives in the referenced to the same 'disk' slots within unRAID as I made a note of them before hand.

 

I am not sure how to proceed...  Ideally I would like to get back to a working parity sync'd server without the 2 new drives and then to clear them properly in another machine before re-adding them one at a time back to the array.

 

Thanks for any help I can give any further info if required.

 

Edit: v4.6

You have two options here:

 

Easy but slightly risky option is to use run 'initconfig' from the command line (system console or telnet).  This will make unRAID forget about the new disks and rebuild parity based on only the disks physically in the system.  The risk is that if any data disk fails during this time, you would likely lose data.

 

The more difficult but minimally risky option is to follow the Trust My Parity procedure.

 

Whichever path you choose, I recommend that you run a parity check right now with the two new (unwanted) disks just to make sure that all the other parity and data disks are healthy.  If any of the disks are dodgy, then I would wait for expert help before taking either of the risks above.

Thank you. I took the plunge and ran initconfig.

 

Parity is now sync'ing again.
