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,

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