I was having trouble setting the snap reserve to 0% on our mirror, it keeps on giving dumb df output, as it has used over 100% of the disk?
snap reserve: volume vol0 is snapmirrored, operation not permitted
Any idea how to do this?

On older releases the snap reserve value was set to 20% on snapmirror destination volumes no matter what. Since you couldn't write or create snapshots on the destination volume, this only caused confusion when looking at the df output. In later releases, the snap reserve value was set to match the source volume value.
So you cannot set the snap reserve value on a destination volume directly. In previous versions it would always set it to 20% in later versions it is set to the same value as the source volume.
