I've a problem similar to the one here:
http://forum.proxmox.com/threads/23...-zfs-install-cannot-import-rpool-no-such-pool
but for me is NOT due to some RAID metadata still present (I've zeroed the entire disk and also tried with a disk brand new)
and that's why I've abandoned that thread and opened this new one.

At boot I have:
Code:
Loading, please wait...

Command: /sbin/zpool import -N rpool
Message: cannot import 'rpool': no such pool available
Error: 1

No pool imported. Manually import the root pool
at the command prompt and then exit. 
Hint: Tyr: zpool import -R /root -N rpool

BusyBox v1.22.1 .... 
/ #
If I do:
Code:
# zpool import
   pool: rpool
     id: 4282105346604124069
  state: ONLINE
 action: The pool can be imported using its name or numeric identifier.
 config:

    rpool       ONLINE
      sda2      ONLINE
From Busybox I'm able to boot one time doing this:
Code:
# zpool import -d /dev/disk/by-id rpool -R /root
# exit
failed to mount root filesystem 'rpool/ROOT/pve-1'
# exit
(isn't strange I've to issue "exit" two times?)

I've tried this, as suggested in previous thread
Code:
# zpool set cachefile= rpool
# update-initramfs -k `uname -r` -u
# reboot
But the problem is not solved, I land in BusyBox again.

Don't know if is relevant, but if from busybox I enter "exit" two times I have the second time:
Code:
Target filesystem doesn't have requeste /sbin/init
mount: mounting /dev/ on /rot/dev failed: No such file or directory
No init found. Try passing init= bootarg.
modprobe: module ehci-orion not found in bodules.dep
Busybox ...
(initramfs)
But I don't know if the "ehci-orion" stuff is a problem (once booted I don't see such a module used by the system)

The MB is an Intel S2400SC, that has 8 HD bay, 4 connected with a "mini-sas to mini-sas" to onboard controller (set as AHCI mode, I guess the "C602"), the other with a "sata to mini-sas" (I guess the "C600").
I've the same problem in any bay.
With lspci I have (leaving more or less only info about HD controller)
Code:
root@pve4:~# lspci | grep controller
00:16.0 Communication controller: Intel Corporation C600/X79 series chipset MEI Controller #1 (rev 05)

and for kernel modules (removing for brevity what I think is not related, like IP stack)

I started with 4 disks in RAID10 but since was unable to boot I did a lot of experiments. To have put things to the minimum, now I've just one WD in the bay (I've tried to move from the first bay to the second bay, since are under different controllers, but no luck) and I've tried ext4 (that works fine) and ZFS (that does not).
At the moment I've only one HD (for ZFS raid0) and I boot / install proxmox from USB stick.
Any help is very apreciated, if I can't solve soon I have to abandon the idea of using ZFS.

Proxmox 4.1 was installed from a USB stick. The ZFS pool resists on two Micron_M600 SSDs (zraid1). The option, that helped on the older machine - rootdelay=10 (or 20) doesn't work. So I have to import the Zpool on every reboot.

hi,

since Promox 4.2 no changes. I have to do zpool import -d /dev/disc-by-id and than exit to get booting. One machine boots without problems, zraid-1, two others won't boot automatically. They have two Micron_M600 SSDs ... maybe, that is the problem.
