Re-install 4.x over 3.x disk issue

[MikeC]

Hey all.

Do I need to do anything special to upgrade my Prox 3.x to Prox 4 other than re-run the installer from USB?
I'm unable to use RAID0 as an option on the existing raidset. I doubt it's a disk error since they're brand new and worked fine under prox3. Do I need to re-format them first? Is there an option to do that in the installer?

I'm seeing errors like, "cannot read /dev/sdb", "Unable to install i386-pc boot loader on /dev/sdb", "unmount: /rpool/ROOT/pve-1/var/lib/vz: not mounted".

Thanks.

Thanks, Tom. I did start there and decided instead of doing an in-place upgrade, I'd just wipe and re-install.
