I'm running a trial of RHEV 3.4 and decided to run through our DR plan. I have two storage domains. vm-store aws_storage_gateway vm-store is the domain which contains all local VM's which would be considered important. I must have put vm-store into maintenance mode before aws_storage_gateway which caused aws_storage_gateway to become the master domain. It also happens to be non-existant now after recovery, as the DR process is to re-create this SD with new disks as all the data is on aws anyways. Is there a method of changing the master storage domain when all domains are in maintenance mode? If I attempt to destroy it I get a UI error: Error while executing action: Cannot destroy the master Storage Domain from the Data Center without another active Storage Domain to take its place. -Either activate another Storage Domain in the Data Center, or remove the Data Center. -If you have problems with the master Data Domain, consider following the recovery process described in the documentation, or contact your system administrator. I tried to fake the storage domain by creating another one, copy in the file structure, and renaming the folder uuid and updating the meta file to match the missing SD without luck. Can I update the db storage pool reference with the vm-store SD uuid? engine=# select * from storage_pool; id | name | description | storage_p ool_type | storage_pool_format_type | status | master_domain_version | spm_vds_id | c ompatibility_version | _create_date | _update_date | quota_enforcement_type | free_text_comment | is_local --------------------------------------+---------+-------------------------+---------- ---------+--------------------------+--------+-----------------------+------------+-- ---------------------+-------------------------------+------------------------------- +------------------------+-------------------+---------- *5849b030-626e-47cb-ad90-3ce782d831b3* | Default | The default Data Center | 1 | 3 | 2 | 19 | | 3 .3 | 2014-05-29 19:46:50.199772-04 | 2014-07-10 09:24:22.790738-04 | 0 | | f (1 row) Thanks, Steve
