This suggests that there is some kind of bug in the layered storage
software. ZFS doesn't do anything special to the underlying storage
device; it merely relies on a few ldi_*() routines. I would try running
the following dtrace script:
#!/usr/sbin/dtrace -s
vdev_disk_open:return,
ldi_open_by_name:return,
ldi_open_by_path:return,
ldi_get_size:return
{
trace(arg1);
}
And then re-run your 'zpool create' command. That will at at least get
us pointed in the right direction.
