Ah, I see, thanks for clarifying. Yes, it's ZFS on Linux (ZOL) exactly.
The gpt partitioned disk layout:

Number  Start (sector)    End (sector)  Size       Code  Name
   1            2048         2019327   985.0 MiB   BF00  ZFS
   2              64            2047   992.0 KiB   EF02  ESP
   3         2019328       203345919   96.0 GiB    BF02  ZFS l2arc
   4       203345920       209983551   3.2 GiB     BF02  ZFS slog
   9       209983552       209999966   8.0 MiB     BF07  ZFS reserved

Part #1 contains a (single disk vdev) pool with a debian root 
file-system and /boot/grub. Part #2 (fat12) is mounted at /boot/efi.
Part #3 and #4 are part of another ZFS pool. It is an EFI system.

To rule out file-system issues, I scrubbed the pool first, which 
completed without error.
Grub (grub-efi-amd64) version is 2.02-beta2.9-ZOL12-7aa9f6-wheezy, but 
I'd update to 2.02-beta2.9-ZOL13-677dca-wheezy. These are grub packages 
from the ZOL repository with ZFS related patches.

How I installed grub? IIRC, I've installed grub by the command
# grub-install --recheck --bootloader-id zrescue.
when I redid this in a chroot, via
# grub-install --bootloader-id zrescue --recheck --verbose /dev/sdi,
it finished, no errors reported.

I'll update grub, redo grub-install as above and report back. Thanks.
