[PVE-User] Best way to RAID1 a Proxmox VE server?

[mykel at mWare.ca]

Hi Theron, thanks for the anecdote... I am certainly familiar with RAIDs 
and their characteristics, my problem is that I'm out of touch with 
Linux specifically - spent too much time in FreeBSD lately.

I'm moreso looking for a 'how-to' for mirroring the second drive in my 
PVE server... hopefully without any extended downtime or reloading of 
the OS being required.

Suggestion for the bare-metal installer - provide RAID1'ing as an 
option? I understand the LVM/PV jazz makes it possible to do this after 
the fact, but it'd sure be nice to have it from the get-go :)
