Dell R730 not finding ZFS boot drive

[thommo17]

Hi Everyone,

I just installed the latest Proxmox VE onto a DellR730 with a PERC H730 running in HBA mode with 4 SSD's.

I set up the SSD's as a ZFS and it was showing 2 partitions. One named local and the other named local-ZFS and from what I understand the local partition was where the boot image would have been stored.

Now I have restarted the server and it doesn't recognise any of the SSD's as boot devices. It doesn't even give me the option to try and boot from them even though they are all being see by the H730. It only shows the CD/DVD drive and if I plug in the USB I used to install everything it will see that in the boot menu too.

It is booting in as BIOS and not UEFI and looking through the other options in the BIOS I can't see anything that might affect it.

Did I do something wrong by installing Proxmox onto the ZFS?
Any suggestions on something I can try out?

The pics attached are what I see on the boot menu and what happens if I select the H730 as a boot device

Thanks!

I'd just like to update this for others who may have this issue.

I had to change boot mode in the BIOS from BIOS to UEFI. I also changed some settings in the H730 but they didn't seem to change anything before I went to UEFI mode.

Now it can see the SSD's as bootable and work fine

Was this an H730 running in HBA mode? I think I ran into the exact same problem today. Good to know switching to UEFI mitigates the issue.

Yeah it was the H730 in HBA mode.

Everything has been running smoothly since
