Just to try this out, I created a 9g zpool and a 5g volume in that zpool.
Then I used dd to write to every block of the volume.
Taking a snapshot of the volume at that point attempts to reserve an

there could be one ? If so what is the basis for the (incorrect)
assumption ?

Hi,
Can ZFS snapshot be performed at zvol size of 100GB ?
