@crazy2bike Copying the data over the network is slow, but it’s also probably the only option. I suppose you could try using a USB SATA adapter. Proxmox is Linux-based, so it should be able to understand LUKS and whatever filesystem is on the old drive (ext4?).

A single spinning disk doesn’t go a whole lot faster than 1g network, though, so it’s probably not worth the hassle. Just set up your new mirror and rsync over the 1g network.

Warum? Du kannst doch die luks auf dem proxmox-host aufmachen: dann hast du ein /dev/mapper/foo in der Hand, dass du in die TrueNAS VM als device reinreichen kannst.
