You can use dd. You may need to set the volmode depending on your
platform to get access to the volume's device node.
/dev/zvol/<poolname>/<zvolname>

Hi,
I fear this may be wrong list... I googled, found and joined it...
let me know if I've got it wrong...
I have a situation where I want to do the equivalent of "dd" the
content of a zfs volume out to have effectively a copy of the raw device.
I've got zfs send > x.out and zfs receive < x.out working, but I'm
not sure how to interact with the zfs volume at a block level...
presumably there must be a way to get the equivalent of a
dd if=<blockdevice> of=/copy-of-blockdevice.dd ?
such that if I needed to use copy-of-blockdevice.dd on another system
without ZFS I could write it do a physical drive?
I think I'm missing something fundamental. I've read that zfs can do
blockIO (with volumes), but *I* can't seem to find out how to
interact with it on that level...
Regards,
Dave
