Storage efficency Change log 100%

Storage efficency shows Change log 100%. I can not stop or restart process.

::> volume efficiency start -vserver <vserver> -volume <volume> -scan-old-data true

give me

Error: command failed: Failed to start efficiency on volume "XXXXXXX" of Vserver "XXXXX": Operation is currently pending.

Any ideas on how to fix that ?

If you get change log 100%, it means you either

1) reached maximum deduplication efficiency possible, yes, there is a limit

2) or you simply do not have free space in your volume.

In any way, I would strongly suggest familiarizing yourself with TR-4476

Find out that I run into the bug :

Only current ways to workaround the issue is either a takeover/giveback of the node or doing an offline/online of the volume
