Hi,
Yesterday someone powered off our storage, and all my 3 hosts lose
their disks. After 2 days of recovering i managed to bring back
everything, except engine VM, which is online but not visible to
itself.
I did new deployment of VM, restored backup and started engine setup.
After manual database updates, my all VMs and hosts are OK now, but
engine. I have engine VM with different VM id running than in
database.
I've tried this with no luck.
engine=# update vm_static set vm_guid =
'75072b32-6f93-4c38-8f18-825004072c1a' where vm_guid =(select
vm_guid from vm_static where vm_name = 'HostedEngine');
ERROR: update or delete on table "vm_static" violates foreign key
constraint "fk_disk_vm_element_vm_static" on table "disk_vm_element"
DETAIL: Key (vm_guid)=(d81ccb53-2594-49db-b69a-04c73b504c59) is still
referenced from table "disk_vm_element".
Right now i've deployed engine on all 3 hosts but see this picture:

Also my storage domain for hosted engine is inactive, can't activate
it it gives this error in web console:
VDSM command GetImagesListVDS failed: Storage domain does not exist:
(u'c44343af-cc4a-4bb7-a548-0c6f609d60d5',)
It seems I should fiddle with database a bit more, but is't scary thing for me.
Any help?
Best regards,
Misak Khachatryan
