Richard,

The auto test passed, but I now cannot mount any tape from within bacula, 
either completely new (i.e. unlabeled) or filled completely with bacula 
backups.  It always thinks the tape is not labeled, giving errors like these:

block.c:1012 Read error on fd=5 at file:blk 0:0 on device "IBMLTO4-0" 
(/dev/nst0). ERR=Device or resource busy.
3902 Cannot mount Volume on Storage Device "IBMLTO4-0" (/dev/nst0) because:
Requested Volume "" on "IBMLTO4-0" (/dev/nst0) is not a Bacula labeled 
Volume, because: ERR=block.c:1012 Read error on fd=5 at file:blk 0:0 on 
device "IBMLTO4-0" (/dev/nst0). ERR=Device or resource busy.
3905 Device "IBMLTO4-0" (/dev/nst0) open but no Bacula volume is mounted.
If this is not a blank tape, try unmounting and remounting the Volume.

====

Here's the kernel version Ubuntu installed: 9.10

# uname -a
Linux claustrum 2.6.31-17-server #54-Ubuntu SMP Thu Dec 10 18:06:56 UTC 
2009 x86_64 GNU/Linux

Perhaps some part of the tape handling is broken in that kernel?  Anybody 
else running bacula on Ubuntu 9.10?
