Hi all
I declared a second device in the disk autochanger, but the same problem occurs
when trying to truncate volumes while a backup job is running.
I also have set MaximumConcurrentJobs to 5, so this shouldn’t be the problem.
It seems that the second device which I declared in the autochanger is not used
for the truncating:
truncate pool=pool1 storage=storage1
Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"
Connecting ...
3908 Error reserving volume: vol_mgr.c:418 Cannot free Volume “pool1-vol-0599",
because it is reserved by someone else.
Error truncating Volume “pool11-vol-0700"
3908 Error reserving volume: vol_mgr.c:418 Cannot free Volume “pool1-vol-0599",
because it is reserved by someone else.
Error truncating Volume “pool1-vol-0703”
This is how I declared the second device in the disk autochanger (dev1 and dev2
are declared identical):
director config file:
Storage {
Name = “storage1"
Device = "changer1"
MediaType = “file1"
MaximumConcurrentJobs = 5
}
SD config file:
Autochanger {
Name = “changer1"
Device = “restore1"
Device = “dev1"
Device = “dev2"
ChangerDevice = "/dev/null"
ChangerCommand = "/dev/null"
}
Device {
Name = “dev1"
MediaType = “file1"
DeviceType = "File"
ArchiveDevice = "/mnt/folder1"
RemovableMedia = no
RandomAccess = yes
AutomaticMount = yes
LabelMedia = yes
AlwaysOpen = no
Autochanger = yes
MaximumConcurrentJobs = 5
}
Device {
Name = “dev2"
MediaType = “file1"
DeviceType = "File"
ArchiveDevice = "/mnt/folder1"
RemovableMedia = no
RandomAccess = yes
AutomaticMount = yes
LabelMedia = yes
AlwaysOpen = no
Autochanger = yes
MaximumConcurrentJobs = 5
}
