It's good article explains about how to use ZFS for replication.

Hi everyone,
Recent ZFS admin guide updates/troubleshooting wiki include the
following updates.
1. Revised root pool recovery steps.
The process has been changed slightly due to a recently uncovered zfs
receive problem. You can create a recursive root pool snapshot as was
previously documented.
I've tried putting this in /etc/system and rebooting
set zfs:zfs_vdev_max_pending = 16
Are we sure that number equates to a scsi command?
Perhaps I should set it to 8 and see what happens.
(I have 256 scsi commands I can queue across 16 drives)
I still got these error messages in the log.

Thanks Tomas, I haven't checked yet, but your workaround seems feasible.
I've posted an RFE and referenced your approach as a workaround.
That's nearly what zpool should do under the hood, and perhaps can be done
temporarily with a wrapper script to detect min(physical storage sizes) ;)

For the sake of curiosity, is it safe to have components of two different ZFS
pools on the same drive, with and without HDD write cache turned on?
How will ZFS itself behave, would it turn on the disk cache if the two imported
pools co-own the drive?
An example is a multi-disk system like mine

But it doesn't "touch it" so ZFS continues to work if you enable
