Re: [Bacula-users] tape drive on 2nd server
Hi Adrian, Thanks for the info. I will look at that URL. I tried to setup the iSCSI and was able to successfully control the autochanger. However, I tried to configure the tape drive as pass-through, and seem to get some issues. I was lacking time, so I finally switched the servers, and make the single CPU with tape drive the main Bacula server, and the dual CPU with disk mounted as NFS. This works, but I was hoping to have the other way so that my backups would be faster. My full backups are quite long. When I have a chance, I'll revisit my config and try it again.

This works, but I was hoping to have the other way so that my backups would be faster. My full backups are quite long. Sorry for the delay in my answer. I saw this email just now. I have it working with an arch linux machine using the TGT iSCSI Target (on arch it's available from th AUR repository). I'm usually a FreeBSD user and had a working setup with FreeBSD and the net/istgt target. BTW lately another implementation (opentgt) was added to the FreeBSD ports collection, but I have not tested it. I had to move it to linux because HP (it's driving an HP changer) would not assist us with hardware problems if I was not using windows or linux. It's been linux since then. Not mush documentation around, I can give you this recipe for arch linux+tgt, I hope it translates easily to other linuxses. I have the following in /etc/tgt/mytargets: TGT=/usr/sbin/tgtadm IQN=iqn.2012-01.org.test.machine:Ultrium INI=192.168.1.1 $TGT --lld iscsi --op new --mode target --tid 1 -T $IQN $TGT --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 \ --bstype=sg --device-type=pt -b /dev/sg3 $TGT --lld iscsi --op new --mode logicalunit --tid 1 --lun 2 \ --bstype=sg --device-type=pt -b /dev/sg4 $TGT --lld iscsi --op bind --mode target --tid 1 -I $INI $TGT --lld iscsi --mode target --op update --tid 1 \ --name MaxRecvDataSegmentLength --value 65536 $TGT --lld iscsi --mode target --op update --tid 1 \ --name MaxXmitDataSegmentLength --value 65536 sg3 is the tape, sg4 is the changer control. The will appear as LUN1 and LUN 2 on the iscsi device, as tgt will pick LUN 0 for itself. I modified the startup script in /etc/rc.d (arch way, other linux use /etc/init.d I think) to use the above script to configure targets. Not using authentication since it's a private network unaccessible from anywhere else. Anyway adding authentication is just a matter of a few more tgtadmin lines. When I have a chance, I'll revisit my config and try it again. Hope the information I gave you helps. I can also dig out the configuration I was using with FreeBSD for it. The bacula server is a FreeBSD 9.0-STABLE machine. If you need some more help just ask. Just CC me directly, so I notice the email earlier. -- Guido Falsi m...@madpilot.net -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

I use in my case a second bacula-sd which connects to an auto changer for the month job. There are a number of different reasons why using a storage volume mounted over NFS for Bacula is likely to be a bad idea, beginning with the difficulty of obtaining effective file locking and the likelihood of poor throughput.
