How to install Proxmox to SSD and mirror?

[baron164]

I have some used server hardware I'm looking to acquire for new homelab Proxmox hosts. The only issue is that there are no hardware raid controllers in these machines. The servers however have room for two SSD's internally. I would like to install Promxox onto an SSD on Sata I and then mirror that to another SSD on Sata II. Is this something that could be done during the install of Proxmox using an LVM? This would only store the system volume, not VMs.

Depending who you ask, not having HW raid isn't a bad thing. I personally replaced all HW raid cards with a dumb HBA for ZFS anyway.
The PVE installer won't allow you to have mirrored LVM. Whats an option is a ZFS or btrfs mirror.

Ok, a btrfs mirror sounds good. As far as Proxmox is concerned is there a better option between ZFS and btrfs or are they pretty comparable?

Btrfs is still experimental so I would go with ZFS which is well tested and more mature.

Ok, I'll give ZFS a try and see how it goes, thanks.
