Re: [Bacula-users] Bacula fails to backup jobs to Tape

Hi Martin,

We are running bacula 5.0.1-1ubuntu1 on Ubuntu Server 10.04. Tsi-vms01-fd is a dedicated

machine which is used as our fileserver, and has the following ethernet card:

Ethernet controller: Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express (rev 21)

The backup01-sd is a vmware virtual machine running on an ESX host, has a SCSI tape unit connected to

it, and emulates this network card:

Ethernet controller: Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE] (rev 10)

Neither tsi-vms01-fd nor backup01-sd logged an error at the time the error occurred. I have tried Francisco's

suggestion to use /dev/nst0 instead of /dev/st0, which also seems to work with btape test, but also throws the same

I/O error at some point.

Our tapes have a label written on it which says: 'IMB TotalStorage LTO Ultrium 400GB uncompressed, 800GB compressed'. The tape unit itself has a label 'IBM TotalStorage LTO Ultrium 3'. The fileserver job takes at least 500GB. I suspect that the tape gets full at some point, and that bacula doesn't detect this. The backup01-sd configuration is:

Device {
Name = "Tape Device"
Media Type = IBM
# Archive Device = /dev/st0
Archive Device = /dev/nst0
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = no;
RemovableMedia = yes;
RandomAccess = no;
## Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg1
## AutoChanger = yes
# # Enable the Alert command only if you have the mtx package loaded
## Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
## If you have smartctl, enable this, it has more info than tapeinfo
## Alert Command = "sh -c 'smartctl -H -l error %c'"
}

Thanks in advance for your help,

The job failed with an unexpected error:

08-Jun 00:20 tsi-vms01-fd JobId 267: Fatal error: backup.c:892 Network send error to SD. ERR=Input/output error

which means that the fd got Input/output error while writing to the sd via a
socket.

I've never seen ERR=Input/output error from a socket connection.

What hardware connects tsi-vms01-fd and backup01-sd? Is it reliable?

Did tsi-vms01-fd log any error around that time, e.g. in /var/log/messages?
