Hi Giorgio, Apperantly the issue is caused because there is no connectivity to the export domain and than we fail on spmStart - that's obviously a bug that shouldn't happen. can you open a bug for the issue? in the meanwhile, as it seems to still exist - seems to me like the way for solving it would be either to fix the connectivity issue between vdsm and the storage domain or to downgrade your vdsm version to before this issue was introduced.
by the way, solution that we can go with is to remove the domain manually from the engine and forcibly cause to reconstruction of the pool metadata, so that issue should be resolved. note that if it'll happen for further domains in the future the same procedure would be required. up to your choice we can proceed with solution - let me know on which way you'd want to go.

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.

StorageDomainDoesNotExist: Storage domain does not exist: (u'1810e5eb-9eb6-4797-ac50-8023a939f312',)
What's the output of: lvs vdsClient -s 0 getStorageDomainsList
If it exists in the list, please run: vdsClient -s 0 getStorageDomainInfo 1810e5eb-9eb6-4797-ac50-8023a939f312
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.
