I have three disks in my Freenas. I had them divided into two volumes. Now I wanted to convert them into one volume. So I detached both volumes and started the Volume Manager to create a new volume with all three disks. I selected the three discs, selected ZFS, checked “enable full disk description!” and “Initialize with random data”, selected RAID-Z and added the volume. I took a while and after it was done, the volume did not show in the list.

I tried the same procedure again but I got some message saying that it can not access the database (I forgot the exact message).

I rebooted the system, wiped the disks manually and tried it again. Still no volume. Now I get the following message when I look at the shell:

freenas [middleware.exceptions:38][MiddlewareError: Unable to GPT format the disk “ada0”]

How can I fix this?

PS: I saved the data before I made any changes
