Resizing EBS with ZFS on AWS

Hi,

I recently started an EC2 with the 14.0 ZFS AMI

After filling the drive, I expanded it, recovered the gpart partition
and expanded the partition and zpool size and kept going.

Then I saw that I would need more space, so I have expanded the EBS vol
again, while the EC2 was shutdown. This time the EC2 will not boot.

Using the EC2 console I get to...


nvme0: SET_FEATURES (09) sqid:0 cid:15 nsid:0 cdw10:0000000b cdw11:0000031f
nvme0: INVALID_FIELD (00/02) crd:0 m:1 dnr:0 p:1 sqid:0 cid:15 cdw0:0

Trying to mount root from zfs:zroot/ROOT/default []...
Mounting from zfs:zroot/ROOT/default failed with error 2: unknown file
system.
GEOM: nda0: the secondary GPT header is not in the last LBA.


What can I do at mountroot> to recover gpart? or boot from here?
