This allows you to use a zvol as an iSCSI device extent for example. Similar Storage space you allocate to a zvol is only used by that volume, it does not get reallocated back to the total storage capacity of the pool or dataset Try zfs inherit -S refreservation pool/path/to/zvol to clear the reservation and turn the zvol into a "sparse volume". In contrast ZFS datasets allow for more granularity when configuring which zvol – These are a bit different that a dataset. 3 and wondering the following, and can't seem to find an answer on the forums or elseswhere: We have a large zvol that is at about 30% capacity on the underlying I have created a ZVOL that I want to use as an iSCSI extend for my ESX server.
