Bacula backup write error

Hi Guys,

I am trying to implement bacula backup and i am having very big problems.I am having 10 client for my backup server it will run backup 4 or 5 client fine and then my volume status is changing to full because of the following error

30-Mar 15:38 backup01-sd: NightlySave1.2006-03-30_15.21.00 Error: block.c:552 Write error at 5:6714 on device

/dev/nst0. ERR=Input/output error.
30-Mar 15:38 backup01-sd: NightlySave1.2006-03-30_15.21.00 Error: Error writing final EOF to tape. This tape may

not be readable.
dev.c:1213 ioctl MTWEOF error on /dev/nst0. ERR=Input/output error.

can some one help me why my backup is not completting and the solution for this problem

i am running dell power vault 114T tape drive with debian sarge kernel version 2.4.27

Ok, this is a changer, right? Is it bombing right when one tape would be full?

I think what's happening is that the bacula daemon doesn't have rights to send the hardware command to the changer to make it change the tape. The dirty way to fix this is to have the bacula daemon run as root, but a better way would be to create a user for the daemon and give it the rights it needs.

I'm sure you've been here: http://www.bacula.org/rel-manual/Autochanger_Support.html#SECTION000291000000000000000

here's another good one: http://www.freebsddiary.org/digital-tl891.php

hmm, 114t comes up as a changer when i look at dell. you sure? if it has the robot arm in it you need to load the autochanger stuff for bacula.

Unit Attention is usually just a normal informational type message. Any time a drive is powered on, a tape is loaded, a tape is ejected a Unit Attention will happen. It is a problem when the SCSI bus is hung and a Unit Attention is sent to reset the bus and regain communication with the device.
