pool they may need to override automatically detected ashift value.
This will all depend on the exact hardware they are using.

Sets the given pool properties. See the "Properties" section for a list of valid properties that can be set. The only property supported at the moment is \fBashift\fR. \fBDo note\fR that some properties (among them \fBashift\fR) are \fInot\fR inherited from a previous vdev. They are vdev specific, not pool specific.
