Issue

  • FlexCache origin volume consumes huge amount of space using by reserved space for overwrite.

Example:

::*> 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

  • Volume efficiency is in deprioritized state.

Example:

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