Error on migrating database

[admin2215]

Upon attempting to migrate the management database I get the following error. The link does not seem to have anything to do with the issue I am experiencing. 

Unable to move management database.    Error: Could not execute command on device (ER122). 

Copy the link below to find more details about the error code.

Reviewing the logs shows the following error:

Hello,

Can you please share the external share mounted on ELM? Do you have a dedicated share mounted for ELM and does it has the necessary space available to accommodate the current management DB resides locally on ELM ?

What's the error you're getting in messages log from command line of ELM at the same time migration is failing on GUI ?

Sure. Let me know the requested particulars to proceed further investigation.

Here is a picture of my shares. To clarify the database was migrated already to an external server and is not locally on the ELM. We need to move it to server that has faster storage and network connections . I recreated the Database_Main today (which is where we want to move the management database to) and made it larger than the other database to be sure. Still no luck. I also wrote to the cluster as requested, and no luck there either. The only message I am getting from /var/log/messages is this:

Thanks for your clarification. We need to perform manual migration of data between the management DBs. Kindly proceed to raise a service request with McAfee technical support and share the SR number here.
