Hi,
I'm using a Bacula setup in conjunction with a Dell PV-124T which has 16 LTO-5
tapes. The system works correctly except that the tapes become extremely
quickly. There is no consistency between the amount written to each tape though
it is generally in the range of 30-130gb - far less then the expected volume.
I'm not getting an error messages in either dmesg or kern.log, there are no
errors when swapping between tapes bacula simply gets back a -1 from the tape
drive:
bacula-sd End of Volume "Tape13" at 3:8729 on device "LTO5-Drive1" (/dev/nst0).
Write of 1048576 bytes got -1.
bacula-sd Re-read of last block succeeded.
My dir:
Pool {
Name = LTO5
Pool Type = Backup
Recycle = yes # Bacula can automatically recycle Volumes
AutoPrune = yes # Prune expired volumes
Volume Retention = 45 days # one year
}
Storage {
Name = LTO5
Address = localhost # N.B. Use a fully qualified name here
SDPort = 9103
Password = "<password>"
Device = PV-124T
Media Type = LTO5
Autochanger = Yes
}
Client {
Name = bacula-fd-local
Address = localhost
FDPort = 9102
Catalog = MyCatalog
Password = "<password>" # password for FileDaemon
File Retention = 45 days # 30 days
Job Retention = 6 months # six months
AutoPrune = yes # Prune expired Jobs/Files
}
JobDefs {
Name = "DefaultJob"
Type = Backup
Level = Incremental
Client = bacula-fd-local
Messages = Standard
Pool = LTO5
Priority = 10
Write Bootstrap = "/var/lib/bacula/%c.bsr"
}
Job {
Name = "HeritageJob"
JobDefs = "DefaultJob"
FileSet = "HeritageSet"
Schedule = "WeeklyCycle2"
Storage=LTO5
}
My sd:
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 = 127.0.0.1
}
Device {
Name = LTO5-Drive1
Drive Index = 0
Media Type = LTO5
Device Type = Tape
Archive Device = /dev/nst0
Changer Device = /dev/sg4
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes;
Maximum File Size = 10G
# Maximum Spool Size = 50G
# Maximum Job Spool Size = 20G # will need this is there are concurrent jobs
Maximum Block Size = 1024k
Spool Directory = /home/bacula/tapehold
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
}
Autochanger {
Name = PV-124T
Device = LTO5-Drive1
Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg4
}
If anyone could suggest any possible routes to a solution or perhaps mistakes
I've made in config I would greatly appreciate it.
Thanks,
Bill
