[pve-devel] ZFS alternatives

[Gandalf Corvotempesta]

I do that quite often.
Starting with a small number of expansive disks (like SSDs or NVMEs) and
being able to expand on the fly when needed, allows me to keep running cost
as low as possible

With zfs this is not possible (in a simple way) thus you have to start with
the proper number of disks that you plan to use for some following  years
