I'm trying to install Proxmox on a server that is going to be running Home Assistant, a security camera NVR setup and other sensitive data, I need to have the drives be encrypted with automatic decryption of drives so the VMs can automatically resume after a power failure.

My desired setup:

• 2 Sata SSDs boot drives in a ZFS mirror
• 1 NVME SSD for L2ARC and VM storage
• 3 HDDs in a RAIDz1 for backups and general large storage
• 1 (maybe more added later) HDD for Camera NVR VM.

I'd prefer every drive encrypted with native ZFS encryption automatically decrypted by either TPM 2.0 or manually by a passphrase if needed as a backup.

Guide I found:

I found a general guide on how to do something similar but it honestly went over my head (I'm still learning) and didn't include much information about additional drives: Proxmox with Secure Boot and Native ZFS Encryption

If so

i clone one dataset (tank/a to tank/b) with zfs

and now i want to delete only parent (tank/a)

i wont to have only tank/b now

how to do it?
