adv_file disk ***/_AF_readonly is verifying label

One zfs device which is used in the Legato Networker can not be used for cloning or staging

If we try to unmount the volume we get the above named error!

There is  now no active staging or cloning process on this adv_file, but we can not use it anymore?

We have try Operations:

Recover space

check file system

stage all save sets

Any ideas, without start/stop the whole Networker Server/Service? (-;
