Hello everybody,

I have the following strange effect, which I think that it is not correct, but 
I did not understand the acquiring code for a new volume enough to find why 
this happens.

This is my configuration:

I have 3 servers in total, 
server A and server B have a filedaemon and a storage daemon each, and server 
C has a director that controls both server A and B. 
Server  A and B have a single LTO3 Drive each.

Server A       Server B
LTO3 Drive     LTO3 Drive
Filedaemon     Filedaemon
     |            |
     --------------
           |
        ServerC
        Director
        Catalog DB


When I make a backup in server A and a restore of this backup on server B
I have the problem that I get this error Message: 

"Fatal error: No Volume names found for restore."

It seems that somehow the director does not really understand that the correct 
tape is already mounted, but it IS mounted as I can see by doing "status 
storage".

The following workaround helps me to be able to do a restore as wished:

I simply make a small backup on server B on the tape that was written on 
server A and now is mounted on server B. 

This works like it should, and afterwards I can do my restore without 
problems.

As this works, I can tell that I have no problems with wrong media type etc.
It seems that only after doing this small backup bacula understands that the 
correct medium is available on the target storage and then it can do the 
restore.

Is there an explanation for this behaviour, or is this a bug and I should do 
some deeper debugging?


P.S.: All deamons are Bacula Version 5.0.3 on x86_64, SUSE, with postgresql 

best regards,

Philipp
