[Bacula-users] Bacula is using half size of lto2 tapes

Good morning

I am using Bacula 5.0.2 on CentOS 5.4. We have 2 robotic libraries, one HP G2 autoloader and an Adic FastStor 2. Both are using HP Lto2 Drives.
On the HP library, all is working fine, tapes are marked as full when 265 Gb are written on them , but the issue is on Adic, the tapes are marked as full when 110 Gb are written on them. I don´t know what can i modify on bacula configuration in order to solve it. Before Bacula, i were using Backup Exec and Adic was working fine with their tape corresponding capacity.

This are (in my opinion, let me know please if further information is required) the most important configurations:

pool.conf file

Pool {
Name = MexicanPool
Pool Type = Backup
Storage = Adic
Recycle = yes                       # Bacula can automatically recycle Volumes
AutoPrune = yes                     # Prune expired volumes
Volume Retention = 30 days         # one year
Storage = Adic
Cleaning Prefix = "CLN"
Action On Purge = Truncate
}

Pool {
Name = ChinaPool
Pool Type = Backup
Storage = HP1x8G2AUTOLDR
Recycle = yes                       # Bacula can automatically recycle Volumes
AutoPrune = yes                     # Prune expired volumes
Volume Retention = 30 days
   Cleaning Prefix = "CLN"
#Action On Purge = Truncate
}

Password = "password"          # password for Storage daemon
Device = HP1x8G2AUTOLDR    # must be same as Device in Storage daemon

}

bacula-sd.conf on Server with HP Library

}

Device {

# #
# # Enable the Alert command only if you have the mtx package loaded
# # Note, apparently on some systems, tapeinfo resets the SCSI controller
# # thus if you turn this on, make sure it does not reset your SCSI
# # controller. I have never had any problems, and smartctl does
# # not seem to cause such problems.
# #
# Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
# If you have smartctl, enable this, it has more info than tapeinfo
# Alert Command = "sh -c 'smartctl -H -l error %c'"
}

Device {

## Changer Command = "/usr/share/bacula/etc/mtx-changer %c %o %S %a %d"
## Changer Device = /dev/sg0
AutoChanger = yes
# # Enable the Alert command only if you have the mtx package loaded

## If you have smartctl, enable this, it has more info than tapeinfo
## Alert Command = "sh -c 'smartctl -H -l error %c'"
}

I am very grateful if anyone can help me or give me a clue in order to solve it.
Best regards
