Dear,
We have a simple bacula configuration.
And autochanger with two tape device (LTO3 and LTO5), for two kind of
different backups. Both work when they run independently. But If a job on
LTO5 is running the other jobs related to LTO3 are waiting until this jobs
has finished. This is a pain in the ass, because the LTO5 run very long
unique/full backups (along days) then I found that a couple of incremental
backups on LT03 running on the same day. The jobs run on different clients
and event sometimes in different catalogs.
These are the relevant configuration:
*bacula-dir.conf*
Director { # define myself
Name = bacula-dir
DIRport = 9101 # where we listen for UA connections
QueryFile = "/etc/bacula/scripts/query.sql"
WorkingDirectory = "/var/lib/bacula"
PidDirectory = "/var/run/bacula"
Maximum Concurrent Jobs = 10
Password = "YYYYYYYYYYYYYY" # Console password
Messages = Daemon
DirAddress = "xxxxxx"
.....
*bacula-sd.conf*
Storage { # definition of myself
Name = bacula-sd
SDPort = 9103 # Director's port
WorkingDirectory = "/var/lib/bacula"
Pid Directory = "/var/run/bacula"
Maximum Concurrent Jobs = 20
SDAddress = "xxxxx"
.....
Autochanger {
Name = TSM3500
Device = ULT3580-TD3
Device = ULT3580-TD5
Changer Device = /dev/sg7
Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
# %c = changer device
# %o = command (unload|load|loaded|list|slots)
# %S = slot index (1-based)
# %a = archive device (i.e., /dev/sd* name for tape
drive)
# %d = drive index (0-based)
}
Device {
# The TSM3100's first tape drive
Name = ULT3580-TD3
Archive Device = /dev/nst0
Device Type = Tape
Media Type = LTO-3
Autochanger = Yes
# Changer Device = <inherited from Changer>
Alert Command = "sh -c '/usr/sbin/tapeinfo -f /dev/sg5 | /bin/sed -n
/TapeAlert/p"
Drive Index = 1
RemovableMedia = yes
Random Access = no
Maximum Block Size = 262144
Maximum Network Buffer Size = 262144
Maximum Spool Size = 40gb
Maximum Job Spool Size = 30gb
Spool Directory = /backup/spool
AutomaticMount = Yes;
}
Device {
# The TSM3100's second tape drive
Name = ULT3580-TD5
Archive Device = /dev/nst1
Device Type = Tape
Media Type = LTO-5
Autochanger = Yes
# Changer Device = <inherited from Changer>
Alert Command = "sh -c '/usr/sbin/tapeinfo -f /dev/sg6 | /bin/sed -n
/TapeAlert/p"
Drive Index = 0
RemovableMedia = yes
Random Access = no
Maximum Block Size = 262144
Maximum Network Buffer Size = 262144
Maximum Spool Size = 40gb
Maximum Job Spool Size = 30gb
Spool Directory = /backup/spool
AutomaticMount = Yes;
}
*And the storage definitions:*
Storage {
Name = TSM3500-LTO3
Address = "xxxxxx"
SDPort = 9103
Password = "YYYYYYYYYYYYYYYYYYY"
Device = ULT3580-TD3
Media Type = LTO-3
Autochanger = yes
Maximum Concurrent Jobs = 5
}
Storage {
Name = TSM3500-LTO5
Address = "xxxxx"
SDPort = 9103
Password = "YYYYYYYYYYYYYYYYYYY"
Device = ULT3580-TD5
Media Type = LTO-5
Autochanger = yes
Maximum Concurrent Jobs = 5
}
I think that "Maximum concurrent Jobs" variable is well defined (well
maybe the storage definition level should be 1, I do not see a tape writing
jobs in parallel, I checked this and neither work )...but I am not able to
find the misconfiguration.
Any Idea ??
Cheers, I.
