hdsize seems to be ignored

[WoetWoet]

Hi,

I'm trying to install Proxmox on zfs (RAID10) and I specified hdsize to be 100 GB:


However, after installation, it seems like it just used the entire disk:

root@proxmox:~# zpool status
  pool: rpool
 state: ONLINE
  scan: none requested

Not sure what I'm doing wrong. For the record, I'm trying to achieve the following:

- The server has 4x 8 TB drives and I have a bunch of important files and a bunch more unimportant files I want to store on it.
- To use my space optimally, I'd like a small redundant partition of 1 TB on RAID 10 for the important files and a big RAID 0 partition for the unimportant files.
- Even better would be to be able to start off small and extend these partitions as needed, but that might be difficult.
- These partitions will only hold VM images, the actual files will be stored inside the VMs themselves.

How would I be able to accomplish this?

* please post the lsblk output
* only the first 2 disks in a RAID 10 get the reduced size (the second and later pairs are given as a whole to the ZFS pool)
