Hi everyone
We have been facing this issue for a long time, so any help or insight will be
greatly appreciated.
Bacula seem to be working just fine, with the exception of these two situations
below:
1) Bacula cannot reposition the tape and continue using it after it is
unmounted. If the tape stays mounted for the whole week, for example, all daily
backups work fine.
2) Restore jobs work ok, but always with the "ERR=Input/output" error (log
below)
I'm mentioning these situations because they are certainly related to how
bacula-sd is configured. There must be something wrong with our bacula-sd.conf
file, but I can assure you that we are using exactly as suggested by btape
test. Here it is:
Device {
Name = LTO-3
Drive Index = 0
Autochanger = no
Archive Device = /dev/nst0
Maximum Changer Wait = 3d
AutomaticMount = yes
AlwaysOpen = yes
Media Type = LTO-3
RemovableMedia = yes
Offline On Unmount = no
Spool Directory = /var/lib/bacula/spool
Maximum Spool Size = 35gb
RandomAccess = no
LabelMedia = yes
#Hardware End of Medium = No
#Fast Forward Space File = No
Two EOF = no
BSF at EOM = no
}
And here is the restore job log showing the problem:
