Scale can't boot, more than 1 boot-pool found

Scale can’t boot after multiple installations. In the first installation, by mistake, I installed Scale on one of the storage disks, which then I wiped on another machine (deleted every partition). Then reinstalled correctly. Now Scale won’t boot, because “more than 1 boot-pool found”

Wipe the storage disk again, this time overwriting it with zeroes.

Or connect it to a machine that understands ZFS and try the zpool labelclear command on the device.

Tips from the OpenZFS root on ZFS instructions:

If the disk was previously used with zfs:

wipefs -a $DISK

For flash-based storage, if the disk was previously used, you may wish to do a full-disk discard (TRIM/UNMAP), which can improve performance:

blkdiscard -f $DISK

Clear the partition table:

sgdisk --zap-all $DISK

Don’t worked. Wiped the disks overnight with zeros, problem stayed.

Where do I write this? The unbooted / crashed TrueNAS doesn’t recognized the command.

Some live USB environment of your choice.

That wasn’t enough, I had to do this too:
