I am currently using Debian Lenny and bacula  2.4.3-1.


Before I was using I presume something like version 2.2X.


On the earlier version, using a HP Ultrium 448 and LTO-2 tapes of 400GB, i was able to write more than 150 GB to the tape.
After a reboot of the machine, probably also hitting a kernel update (running earlier Debian Etch 2.6.18, after reboot etch 2.6.22) I was not able to access the tape unit any more.


After struggling for some time, decided to upgrade machine to lenny, and the newer bacula version, finaly got me into business again..

However, the max size of tape utilization is now 86,905,018,368 bytes.

See below the /etc/stinit.def file: 
# A reel-to-reel tape with 6250/1600/800 bpi densities
manufacturer=HP model = "Ultrium 2-SCSI" {
can-bsr two-fms
scsi2logical=0
mode1 blocksize=0
}

And the current bacula-sd.conf device definition:
Device {
  Name = TapeStorage
  Media Type = LTO2
  Archive Device = /dev/st0
  Device Type = Tape
  Alert Command = "sh -c 'sudo /usr/sbin/tapeinfo -f %c |grep TapeAlert|cat'"
#  Drive Index = 0
  AlwaysOpen = yes;
  AutomaticMount = yes;               # when device opened, read it
  RemovableMedia = yes;
  RandomAccess = no;
  Requires Mount = no
  AutoChanger = no
  # Enable the Alert command only if you have the mtx package loaded
  Maximum Spool Size = 60000000000
  #Spool Directory = /srv/bacula/spool
  Spool Directory = /var/lib/bacula/spool
}

Does anyone has an idea how to fix my configuration, so I can use the full tape capacity again?


Cheers,

Walter
