Hello,

I've just started using Bacula having installed the RPMs from the Scientific 
Linux distro. I'm trying to back up several machines to disk file on the Bacula 
server and am experiencing two odd problems:

i) disk volumes created by Bacula are changing their state to Error with the 
message that they are a different size to that set in the catalog, is this 
normal?

ii) data throughput is really low The machines are all connected via gigabit 
connections yet I'm seeing less than 6MBytes/s transfer to disk, more often 
than not it is down to 2 Mbytes/s. The raid array I'm using responds at a speed 
of about 70Mbytes/s when i test it with a dd of a few gigabyte from /dev/zero. 
Rsync between the same hosts was very quick, generating nearly 500Mbit/s of 
network traffic.

Can any offer any suggestions?

Thanks,
Graham
