Remove master storage from data center?

Wednesday, 2 March 2016

Hi,

We've migrated storage from glusterfs to iSCSI, so now we have 2 
storages in our data center. As we've already finished, we want to 
remove the gluster storage from our data center (which is the master 
storage right now).

We've tried to put it on maintenance but we're getting this error:

2016-03-02 13:02:02,087 ERROR

vds_spm_id='7'})'

DisconnectStoragePoolVDS, error = Operation not allowed while SPM is 
active: ('fa155d43-4e68-486f-9f9d-ae3e3916cc4f',), code = 656

Does that mean that *all* hosts must be on maintenance to do that? 
There's nothing left on the gluster storage right now.

Thanks.

Nicolás
