Cannot boot Proxmox after Single Drive Chosen ZFS Raid 0

[Gurnsee]

So the story goes, I have been using Proxmox on my IBM X3200 M3 with LSI ServeRAID M5014 and a single 1tb hard drive plus 32gb ram. It has been running amazing for the past year(Hats off to Proxmox!), so I decided to muster my courage and grabbed another server (IBM X3400 M3 also with LSI ServeRAID M5014) from my local vendor to test replication. I understand in order to have 2 nodes replication, the filesystem in both servers must be ZFS. Therefore, I reformatted my X3200 M3 and reinstalled proxmox with ZFS in its single drive. When I tried to boot it for the first time, it said "Hard Drive 0 failed" and failed to boot. I then tried on the X3400 M3 (also with a single hard drive) and the result was the same. I've searched around forum and I know it is possible to install ZFS on a single drive under ZFS (RAID 0), so I'm taking this issue is with the servers themselves? I know people will ask me why I need that RAID card if I only have one drive, but I am planning to add more hard drives in the future when budget allows. So could the RAID card be the reason ZFS RAID 0 doesn't work with proxmox? I don't know if the LSI configuration was wrong but initially I created a virtual drive under Group 0 for that single drive so proxmox can be installed.

Thanks!

PS - I have reverted back to XFS and both servers booted up normally.

The ServeRAID are not optimal for ZFS, as you cannot set them to HBA Mode (which is preferred for ZFS), but normally it should work with a single drive in a Virtual Drive configured as Raid 0

Too bad that the M5014 cannot be reflashed to IT Mode (HBA)

I run some systems with similar controllers from Fujitsu (same LSI Hardware/firmware) with proxmox and ZFS
Maybe there is some other device coming in as Harddrive 0 during the boot process ?

Hmm I loaded into BIOS again to check boot priority, Harddrive 0 is already on the top of Boot Order. After POST, LSI was the only thing loaded before OS.

I can confirm that it won't boot on zfs tried multiple configurations and nothing
Anybody found a solution?

Hi,
I've quite the same configuration as Gurnsee, and I've made it working by going into BIOS and adding LEGACY as the 1st booting device.
Hope this can help.
