HI @eryk_sun 

Yes for that you will need to DOWN the pool.
Can you provide the output from the nbrbutil output (unfiltered - at least the otuput that relates to the disk pool). 
If the system is quiet you could also consider trying "nbrbutil -resetALL" to see if you can clear the curr write stream.
I assume you have expired all images that reside on the volume you wish to remove.

Cheers
David

hello,

try reboot of the master server

Hi @eryk_sun 

Can you tell us what you are trying to achieve by putting the state of the pool DOWN? There may be other ways to do what you are trying without this step - reconfiguring the diskpool should be possible with the pool UP.
