Recovery failed

Hi team,

We are having issue with recovery where it errors out due to topology.

[133620]{-1}[-1/-1] 2014-10-20 17:29:41.192260 f NameServer       TREXNameServer.cpp(02876) : convert topology failed, no mapping defined for host <hostname>> -> stopping instance ...

[14386]{-1}[-1/-1] 2014-10-21 10:57:42.182085 e Backup           TREXNameServer.cpp(05983) : Convert topology: no mapping defined for host <hostname>>

[14386]{-1}[-1/-1] 2014-10-21 10:57:42.182655 e Backup           BackupMgr_Manager.cpp(04594) : RECOVER DATA finished with error: [110092] Recovery failed in nameserver startup: convert topology failed, no mapping defined for host <hostname>>

the topology is same across the two hosts. I am not understanding as to how to trace it .

Lars,

How are you doing today, finally got your response.

Of course not, how are you doing today.

Honestly we didnt have a solution went back to build the system from the golden backup.

Lars, i have raised in my other threads as well there is no way to go back from stats server to emebded stats server.

The only way is restore from the backup roll forward till the point before the start of the migration.

Topology plays a very important here.

So my say would be get the topology right in case refreshes or stats server migrations very important.

There is no monitoring mechanism as to how to perform migration from standalone to embedded stats server.
