Hi Ovirt Team,

how to attach an export domain to a new datacenter with an export domain not very well unattached from an obsolete datacenter ?

My old platform with ovirt 4.1 was deleted ans reinstalled with ovirt 4.2.3.
It's ok but i have a problem with an export domain which has not been unattached before the extinction of the old platform.

When i try to attach this export domain, i have the error message in the gui :

Failed to attach Storage Domain oVirtNFS_EXPORT to Data Center xxx.

How can i reinitialize the export domain without erase the data ? just the manager who own the domain.

I haven't don't it for a long time, but the following procedure used to work:

1. Browse the export domain and find a file called 'metadata' in the dom_md folder.

2. Back it up.

3. Remove the lines with POOL_UUID and _SHA_CKSUM in that file.

Thanks for all.
