I am searching for advice and/or expertise in allowing Bacula to use
multiple tape drives at once.
I currently have two separate jobs that use separate Pools, that run around
the same time. Although the second job is always waiting for the other job
to finish. While the second tape drive is open, I would like for it to use
the second drive and not have to wait for the other drive to be finished.
I also read that setting "MaximumConcurrentJobs = 1" for each will allow
this but I get the same result.
Below is my configuration for the devices:
Device {
Name = "Superloader_LTO9_Drive0"
MediaType = "LTO-9"
DeviceType = "Tape"
ArchiveDevice = "/dev/tape/by-id/scsi-3500308c42b98f114-nst"
RemovableMedia = yes
RandomAccess = no
AutomaticMount = yes
LabelMedia = yes
AlwaysOpen = yes
Autochanger = yes
AutoSelect = yes
ChangerDevice = "/dev/sg5"
ControlDevice = "/dev/sg3"
ChangerCommand = "/usr/libexec/bacula/mtx-changer %c %o %S %a %d"
AlertCommand = "/usr/libexec/bacula/tapealert %l"
MaximumChangerWait = 1800
MaximumOpenWait = 1800
MaximumRewindWait = 300
MaximumFileSize = 2000000000
MaximumConcurrentJobs = 1
DriveIndex = 0
}
Device {
Name = "Superloader_LTO9_Drive1"
MediaType = "LTO-9"
DeviceType = "Tape"
ArchiveDevice = "/dev/tape/by-id/scsi-3500308c42b98f118-nst"
RemovableMedia = yes
RandomAccess = no
AutomaticMount = yes
LabelMedia = yes
AlwaysOpen = yes
Autochanger = yes
AutoSelect = yes
ChangerDevice = "/dev/sg5"
ControlDevice = "/dev/sg4"
ChangerCommand = "/usr/libexec/bacula/mtx-changer %c %o %S %a %d"
AlertCommand = "/usr/libexec/bacula/tapealert %l"
MaximumChangerWait = 1800
MaximumOpenWait = 1800
MaximumRewindWait = 300
MaximumFileSize = 2000000000
MaximumConcurrentJobs = 1
DriveIndex = 1
}
Messages {
Name = "Standard"
Director = bacula-dir = All, !Debug, !Saved
}
Autochanger {
Name = "Autochanger"
Device = "Superloader_LTO9_Drive1"
Device = "Superloader_LTO9_Drive0"
ChangerDevice = "/dev/sg5"
ChangerCommand = "/usr/libexec/bacula/mtx-changer %c %o %S % a %d"
}
Thanks,
Kody
