Re: [Bacula-users] bacula wants me to mount already mounted volume

[Nils Blanck-W. <nil...@ba...>]

Hi Brian,
I am using 2.4.2 on CentOS 5.2
I found out that issuing "update slots" can solve the issue.
It looks like even if bacula itself chose the right volume, loaded it 
from the right slot into the right drive, it sometimes seems to forget 
what it just loaded. When that happens, I do "update slots" and after 
some seconds bacula starts writing to the already loaded tape. Sometimes 
it takes an unload, reload, update slots to fix things.
But this is just my impression. It would take more detailed 
investigation to tell what "really" happened. I turned debugging on so 
maybe next time I'll be able to narrow down the issue.

I really don't think that this is a general problem because in this case 
the mailing list would be flooded with bugreports. Maybe its some kind 
of rare communication problem between bacula and mtx / mt or something 
similar.

Regards, Nils
