Replace zfs disk after disk fault

[schrope]

Hello,
after reading hours in forums for a solution and testing around, I hope someone can help me.

I have a RAIDZ2 with 5 SAS disks. Now one is fault and i wanted to replace it. So I got to GUI and set the fault one offline. Shut the system down and installed the new one.

Code:

 NAME                                            STATE     READ WRITE CKSUM
        zfsZ2                                           DEGRADED     0     0     0
          raidz2-0                                      DEGRADED     0     0     0

            gptid/8ab9e4d9-1deb-11e9-8fe8-0fb6b5299048  ONLINE       0     0     0

Back in the GUI I pressed the replace button but got the following message:

I tried to wipe the disk but nothing helped.
One thing seems trange, that before i installed the new drive, the fault one was on da0 and now it, I installed the new drive in the same bay, it is da5.
Could that be the problem?

Thanks in advance for help!

Did you work through this ;

Hi!
So I worked through this thread, dd worked as mentioned in the thread, but still get the same errors if I tryed to replace the disk.

Code:

[MiddlewareError: Unable to GPT format the disk "da5": gpart: geom 'da5': File exists]

Maybe someone has another idea?

Is it possible to change the "drive-letter" from da5 to da6 or something? I guess somewere in freenas the old da5 is existing and now it's not possible to format this existing and maybe used drive.
