Hello everybody,
I have a problem with a single LTO-5 Tape drive (Tandberg LTO-5 HH).
I do backups spanning multiple Tapes, changing them manually.
So I configured the storage daemon that it is automatically pushing out the
tape as soon as it is full.
So my users (and me) can see this and load a new/the next tape. Than bacula
automatically mounts it and continue with the backup. This works fine.
But problems arise as soon as I have a tape, which is not full and I want
to unload it (for example to label a new tape or to restart bacula or the
server). If I just restart tape is pushed out as soon as bacula is shutting
down or during the restart (it is also rewinded as expected). The same
happens, if I "unmount" the tape using bconsole.
But, as soon as I start a new backup, which wants to use this tape and I
mount it again, bacula cannot find the position to continue with the backup
(someone suggested that this might be due to a missing EOD mark, but if I
write this one manually by mt, this does not change the behaviour).
btape testing is working fine, if I disable the automatic pushout of the
tape (as my tape drive is not able to get the tape back in again by
itself).
Any help/ideas is/are apreciated.
Thank you all in advance!
Christian
Here is my bacula-sd.conf:
Storage { # definition of myself
Name = fritzie15-sd
SDPort = 9103 # Director's port
WorkingDirectory = "/var/lib/bacula"
Pid Directory = "/var/run"
Maximum Concurrent Jobs = 20
# SDAddresses = {
# ipv4 = {addr = 127.0.0.1; port = 9103;}
# ipv4 = {addr = 141.67.100.240; port = 9103;}
# }
SDAddress = 141.67.101.230
}
#
# List Directors who are permitted to contact Storage daemon
#
Director {
Name = fritzie15-dir
Password = "Something-very secret"
}
Device {
Name = FileStorage
Media Type = File
Archive Device = /srv/ag_dudziak_backup1/bacula
LabelMedia = yes; # lets Bacula label unlabeled media
Random Access = Yes;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = no;
AlwaysOpen = no;
Maximum Volume Size = 100G;
Maximum Concurrent Jobs = 2
}
Device {
Name = LTO-5-128K
Archive Device = /dev/nst0
Device Type = Tape
Media Type = LTO-5-128K
Labelmedia = yes
Random Access = no
# AutomaticMount = no
AutomaticMount = yes
RemovableMedia = yes
AlwaysOpen = yes
Maximum Concurrent Jobs = 1
Maximum File Size = 400G
Maximum Changer Wait = 2h
Volume Poll Interval = 5min
Offline on Unmount = yes
# Offline on Unmount = no
Spool Directory = /srv/ag_dudziak/bacula-spool/LTO-5-1M
Maximum Block Size = 128K
}
I sticked to the block size of 128K as anything bigger did not work (even
with btape).
