ProxMox Boot Problem

[eak819]

We purchased a Cybertron Magnum for our ProxMox install. It has a two 80 GB SSD's installed in RAID 1 as well as 8 1TB disks installed in a RAID 10. I seem to be experiencing an issue with the boot loader I chose one of the SSD's for the ProxMox install. The install failed at the "Make system bootable" stage however when I tired to reinstall ProxMox it worked. But the system won't boot, it'll just sit there.

Thanks for your help on this one.

Thanks,
Ethan

Hi Ethan,
if you see 2 SSDs there is no real raid-controller (it's an fake-raid). Can you switch the SSDs to single drives in the bios? With an single drive (and an installed grub) it's should work.

Udo,

Won't I lose redundancy if I take them out of RAID?

Thanks,

Hi,
if you see two SSDs you don't have redundancy...
But of course you can use software-raids, like spirit wrote.

Better use an hardwareraid.

Are your raid-10 an real raid? If your VMs run on the raid 10 and you have an backup from the config, you are able to reinstall pve in a realy short time (perhaps it's enough).

Udo,

Yes they are a real RAID they are connected to the controller. I guess you are right, if one of the SSD's goes out I can always grab my backups and reinstall.

Okay, So we are just going to purchase another RAID controller and setup the SSD's on it in a RAID 1. Then install Proxmox to that RAID, is there anything else that I should watch out for?

Thanks,
