[SOLVED] Please fix ZFS setup first. Error when installing proxmox 4 to zfs raid10

[Christoffer Jönsson]

Hi there! Since proxmox could not find my RAID10 from my motherboard(H97M-e), I need to install proxmox 4 to a software RAID10 instead.

My drives are a mix of WD and Samsung 500gb drives. They are also unallocated.

In the Proxmox installer, I select Options next to Target Harddisk, select xfs RAID10 and my 4 500gb drives. Press OK then Next and I get this error:

Warning: mirrored disks must have the same size. Please fix ZFS setup first.

I really don't get why it does not install, even though one disk is 2MB smaller than the rest.

Thanks!

UPDATE

So I switched out the disk that was 2MB smaller than the others, then it installed ok.

But now I get another error: cannot import 'rpool': one or more devices is currently unavailable. Error: 1

The timing on your problem and the problem this fix solves seems to match. Have you seen this yet?

Its not rc.d startup script problem. Its proxmox install script design result.

I solved this issue by changing

linux /ROOT/pve-1@/boot/vmlinuz-4.2.6-1-pve root=ZFS=rpool/ROOT/pve-1 ro boot=zfs $bootfs root=ZFS=rpool/ROOT/pve-1 boot=zfs quiet

to

linux /ROOT/pve-1@/boot/vmlinuz-4.2.6-1-pve root=ZFS=rpool/ROOT/pve-1 ro boot=zfs $bootfs root=ZFS=rpool/ROOT/pve-1 boot=zfs quiet rootdelay=10

In grub boot meny and /boot/grub/grub.cfg

How do we do this exactly?

How do we do this exactly?

edit the GRUB_CMDLINE_LINUX variable (add "rootdelay=10") in /etc/default/grub and run "update-grub2" afterwards to regenerate the grub configuration.
