Ok, and is the iscsi functional at the moment?
I think so. For example I see in the DB that the id of my Master Data Domain , dt02clu6070, is "a689cb30-743e-4261-bfd1-b8b194dc85db" then
[root@vbox70 ~]# lvs a689cb30-743e-4261-bfd1-b8b194dc85db LV VG Attr LSize Pool Origin Data% Move Log Cpy%Sync Convert 4a1be3d8-ac7d-46cf-ae1c-ba154bc9a400 a689cb30-743e-4261-bfd1-b8b194dc85db -wi------- 3,62g 5c8bb733-4b0c-43a9-9471-0fde3d159fb2 a689cb30-743e-4261-bfd1-b8b194dc85db -wi------- 11,00g 7b617ab1-70c1-42ea-9303-ceffac1da72d a689cb30-743e-4261-bfd1-b8b194dc85db -wi------- 3,88g e4b86b91-80ec-4bba-8372-10522046ee6b a689cb30-743e-4261-bfd1-b8b194dc85db -wi------- 9,00g ids a689cb30-743e-4261-bfd1-b8b194dc85db -wi-ao---- 128,00m inbox a689cb30-743e-4261-bfd1-b8b194dc85db -wi-a----- 128,00m leases a689cb30-743e-4261-bfd1-b8b194dc85db -wi-a----- 2,00g master a689cb30-743e-4261-bfd1-b8b194dc85db -wi-a----- 1,00g metadata a689cb30-743e-4261-bfd1-b8b194dc85db -wi-a----- 512,00m outbox a689cb30-743e-4261-bfd1-b8b194dc85db -wi-a----- 128,00m
I can read from the LVs that have the LVM Available bit set:

Obviously I can't read from LVs that aren't available:
[root@vbox70 ~]# dd if=/dev/a689cb30-743e-4261-bfd1-b8b194dc85db/4a1be3d8-ac7d-46cf-ae1c-ba154bc9a400 bs=1M of=/dev/null dd: apertura di `/dev/a689cb30-743e-4261-bfd1-b8b194dc85db/4a1be3d8-ac7d-46cf-ae1c-ba154bc9a400': No such file or directory [root@vbox70 ~]#
But those LV are the VM's disks and I suppose it's availability is managed by oVirt
please see my previous mail on this thread, the issue seems to be with the connectivity to the nfs path, not the iscsi. 2014-03-04 13:15:41,167 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler_Worker-27) [1141851d] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: Failed to connect Host vbox70 to the Storage Domains nfs02EXPORT.

Master data domain must be reachable in order for the DC to be up. Export domain shouldn't affect the dc status. Are you sure that you've created the export domain as an export domain, and not as a regular nfs?
Yes, I am.
Don't know how to extract this info from DB, but in webadmin, in the storage list, I have these info:
Domain Name: nfs02EXPORT Domain Type: Export Storage Type: NFS Format: V1 Cross Data-Center Status: Inactive Total Space: [N/A] Free Space: [N/A]
ATM my only "Data" Domain is based on iSCSI, no NFS.

I'm attaching a compressed archive to avoid mangling by googlemail client.
Indeed the NFS storage with that id is not in the list of available storage as it is brought up by a VM that has to be run in this very same cluster. Obviously it isn't running at the moment.
You find this in the DB:
COPY storage_domain_static (id, storage, storage_name, storage_domain_type, storage_type, storage_domain_format_type, _create_date, _update_date, recoverable, last_time_used_as_master, storage_description, storage_comment) FROM stdin; ... 1810e5eb-9eb6-4797-ac50-8023a939f312 11d4972d-f227-49ed-b997-f33cf4b2aa26 nfs02EXPORT 3 1 0 2014-02-28 18:11:23.17092+01 \N t 0 \N \N ...
Also, disks for that VM are carved from the Master Data Domain that is not available ATM.
To say in other words: I thought that availability of an export domain wasn't critical to switch on a Data Center. Am I wrong?
Thanks, Giorgio.
