As part of the ARC inception review for ZFS crypto we were asked to
follow up on PSARC/2006/370 which indicates that swap dump will be
done using a means other than a ZVOL.
Currently I have the ZFS crypto project allowing for ephemeral keys to
support using a ZVOL as a swap device.

Hello,
I know, that you had this discussion a view days ago but I'm in the
installation phase of our new production servers and I intend to migrate the
data from UFS volumes to ZFS volumes in near future. For doing this it must be
ABSOLUTELY sure that I can resize the SAN LUNs because during

Hi, I just built a kernel from source yesterday and try to run the new kernel

Treat a pseudo-zvol like you would a slice.
So these new zvol-like things don't support snapshots, etc, right?
I take it they work by allowing overwriting of the data, correct?
yes, and yes
Are these a zslice?
I suppose we could call them that. That's better than pseudo-zvol.
