[SOLVED] Proxmox 5.1 (ZFS) on a Dell Server

[KHosting]

I may be posting this request in the wrong forum but I thought I should ask anyways.

So I am trying to install Proxmox 5.1 on a Dell R430 and would like to use ZFS which will imply that I disable RAID. I tried to disable RAID in server BIOS but now I cannot see any drive on the system.

Please is there anyone here who have been able to install Proxmox on a similar server? How did you manage to disable the RAID controllers?

Any pointer will be appreciated.

I think you might have disabled the controller. You need to change it from raid to hba

It's depend a lot if your RAID card is also HBA o can be flashed in it-mode. If not, you will not able to use this and probably had to create an HW RAID and go to LVM... This is the case that I have on other DELL server.
LVM is probably a few worst, but seem the correct solution in these case.

Hi,
I don't know the r430 server (only r610 + r620).
The newer server should use drives without an raid-signature as pass through drive (like it-mode).
BTW. if you have an internal controller you can't flash them to it-mode!

If an unconfigured drive not show to the OS the only way I know is the crappy lsi way: build single raid0 for each hdd!
It's not the best way, because zfs hasn't the full access to the drive and there are people they say it's not safe, but I don't know another way.

Well, RAID0 with ZFS can work, but it's absolutely not recommended... Personally, I think that in case that there is no HBA or RAID card in it-mode, better go to hw raid with lvm... other setup can be an big problem in case of failure : https://forum.proxmox.com/threads/zfs-over-raid10-hw-wrong-idea.38033/#post-187805

Does it have Perc H330/H730 raid card? There was an issue after setting to HBA mode, that they needed to factory reset the RAID card, and then reboot, and then re-enable HBA mode (non-raid disk mode). See if this helps you:

Thanks you all. So apparently the controller firmware is out of date and need to be updated.

After that I was able to enable HBA mode and Proxmox now able to see the drives. I am assuming this is "pass through" mode mentioned previously.
