The pithy ruminations from "Jeremiah D. Jester" <jjest AT u.washington DOT edu> 
on "[Bacula-users] 124t users?" were:

=> I've been having ongoing issues with bacula and my 124t. Anyone out there 
having any problems? If not, would like to know that as well. Maybe we can 
compare storage conf files?

I've been using Dell PowerVault 132t[1] libraries for about 5. It's not the 
same hardware, but close enough that I may be able to help. We've gone from 2x 
LTO2 (SCSI=>FC bridge) to 2xLTO3 (native FC), and use the system heavily with 
minimal issues...most of which have been:
     
     logical device identification (/dev/nst0 vrs /dev/nst1 not always 
corresponding to the
        same physical drives)

     buggy Linux FC drivers (old issue, gone since Fedora Core 1 in our case)

     mechanical (very rarely a drive doesn't want to eject a tape, the picker 
gets 'stuck') 

The most frequent issues we've had have been with bacula (version 1.38.x 
through 5.0.2) --for example, sometimes it'll repeatedly want to use a volume 
that's not in the changer, despite copious use of "update slots", etc.
