I need help reviewing my config to see if that is the problem or what
else it might be.
I have Bacula 2.2.8 installed on a Linux box CentOS 2.6.9-78.0.8.ELsmp
Disk backups work fine. No problem.
Backing up to Tape I will often have the Autochanger go 'offline'
somehow after a large backup is
finished and have to reset the scsi bus to bring it back into
operation before the next access.
The symptom when it goes offline is this.
[r...@bacula] ~# mtx -f /dev/sg4
[r...@bacula] ~# mtx -f /dev/sg4 status
mtx: Request Sense: Long Report=yes
mtx: Request Sense: Valid Residual=no

I am using an Adaptec 29160 with only the autochanger attached and it
is an ADIC FASTOR2 with
8 slots and 1 drive.
My configuration looks like this
bacula-sd.conf
Device {
Name = FileStorage
Media Type = File
Archive Device = /backup/v1
LabelMedia = yes; # lets Bacula label unlabeled
media
Random Access = Yes;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = no;
AlwaysOpen = yes;
}
Autochanger {
Name = Tape
Device = FASTOR2
Changer Command = "/etc/bacula/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg4
}
Device {
Name = FASTOR2
Media Type = LTO-2
Archive Device = /dev/nst0
Autochanger = yes;
AutomaticMount = yes;
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
}
btape test and autochanger test work fine.
I can do backups and restores fine up to a point, but if I leave a
large backupup running and come in the next day
to look at it I get the above status and no further backups are
possible until I reset the ADIC device controller
and make the system recognize it again.
Should I go after the hardware? I have tried another adaptec
controller, another SCSI cable and terminator but I don't
have another tape library to try.
Any thoughts?
Thanks
