问题描述

  • FlexCache 初始卷会通过预留的覆盖空间占用大量空间。

示例:

::*> volume show -fields vserver,volume,overwrite-reserve,fractional-reserve,snapshot-policy 

vserver  volume       fractional-reserve snapshot-policy overwrite-reserve

-------- ------------ ------------------ --------------- -----------------

vserver1 vol1     0%                 transition_snapshot_policy_8 1882167MB

  • 卷效率处于已取消优先级的状态。

示例:

 ::> volume efficiency show -vserver vserver1 -volume vol1 -instance
 Vserver Name: vserver1
 Volume Name: vol1
 Volume Path: /vol/vol1
 State: Enabled
 Auto State: Deprioritized
 Status: Idle
