I installed hosted-engine on an NFS share on 'NAS a'.

I'd like to move it to 'NAS b' is there an easy way to do this ?

Migrating an hosted-engine env from one storage to another is a new feature we are going to introduce with 4.1.

Basically you have to follow this guide:

http://www.ovirt.org/develop/developer-guide/engine/migrate-to-hosted-engine/

and when you are going to restore the DB backup with engine-backup you have also to add two new options (--he-remove-storage-vm, --he-remove-hosts) to filter out any reference to the previous hosted engine env in order to let the auto import procedure for hosted engine to trigger again.

Unfortunately there is currently an open bug on that and the auto import procedure could fail after that; currently the safest option is to follow this workaround:
