与之间的快照大小存在显著差异vol showdf -h：

::*> snapshot show vol0 ---Blocks--- Vserver Volume Snapshot Size Total% Used% -------- -------- ------------------------------------- -------- ------ ----- vserver-01 vol0 nightly.1 16.82MB 0% 0% hourly.5 9.79MB 0% 0% hourly.3 10.50MB 0% 0% hourly.2 10.23MB 0% 0% nightly.0 18.42MB 0% 0% hourly.1 10.66MB 0% 0% hourly.0 3.86MB 0% 0%

::*> vol show vol0 -fields size-used-by-snapshots vserver volume size-used-by-snapshots --------------- ------ ---------------------- vserver-01 vol0 6.71GB

df输出：

::*> df -h vol0 Filesystem total used avail capacity Mounted on Vserver /vol/vol0/ 1905GB 62GB 1842GB 3% --- vserver-01 /vol/vol0/.snapshot 100GB 6871MB 93GB 7% --- vserver-01
