question about disk sizes

[rickcamge]

Hi everybody,
I have a 250G SSD and a 500G HDD. When I tried to install Proxmox 6 on ZFS raid 1 based on the disks, the installation wizard warned me both disk should have the same size.

I created a 250G partition on the HDD and tried again, but the installation wizard did not recognize the partition but the full disk.

Is there any way to use Raid 1 on these disk ? I just want to maintain some redundancy and avoid disk failure disruption.

Thanks for your help!

The installer will always wipe the disk and so it doesn't looks at current partition layout at all.
But yes, in your case you can specify the "hdsize" (under advanced) to 250G and you should be good. The 500G HDD then has 250G unpartitioned left.
