问题描述

缺少手动快照
已自动删除快照以释放空间
创建快照后的快照列表输出：

CLUSTER::> snap list -vol vol1 ---Blocks--- Vserver Volume Snapshot Size Total% Used% -------- -------- ------------------------------------- -------- ------ ----- SVM_1 vol1 3hour.2022-08-06_0805 74.69GB 4% 9% 3hour.2022-08-06_1105 23.50GB 1% 3% Manual_DR_1 120KB 0% 0% Manual_DR_2 104KB 0% 0% 4 entries were displayed.

EMS日志指示它们已因空间不足而被自动删除：
