Dell TL4000 tape library: running btape and configuring Bacula’s mtx-changer

Leave a Comment / Bacula, FreeBSD, Open Source / By /

In this post, I am using FreeBSD 10.2 and Bacula 7.4.0. I am now the proud second-hand owner of a Dell TL4000. The first thing I did was add an air filter. Why? Because I can. I got one made, with custom dimensions, by DEMCiflex. You can see that filter here in this photo. My next task is configuring the tape library to work with Bacula. The first part of that is mtx-changer […]

This post has been superseded by a newer post. The new SFF-8088 to SFF-8088 SAS cables have arrived and have been connected to the LSI 9200-8E SAS card and to the Dell TL4000 tape library. The updated the dmesg output etc and appear on this page, for future reference. The significant portion is: I will have to investigate those no free space available messages later, but given all the devices are present, I

This post is deprecated by this one. I have a new SAS card for the tape server. This time, we are using an LSI 9200-8E SAS card. I’ve updated the dmesg output etc and put on this page, for future reference. The significant portion is: World, please meet tape01, the newest addition to my home lab, and reincarnated from an old server. The tape library itself is not connected because the cables For

This post is deprecated by this one. After a failed first attempt to get the SAS card working with a tape library, John Baldwin suggested I try mfip (there is no man page for it), but I discovered it was a kernel module. I issued the kdload mfip command, checked /var/log/messages, and found the tape library and drives had been added: Jan 1 00:30:42 tape01 kernel: mfip0: on mfi0 Jan 1 00:30:42 tape01

Oh! There’s my missing tape drive!

Leave a Comment / FreeBSD, General, hardware / By /

Yesterday and today, none of my Bacula copy-to-tape jobs completed because my tape drive was missing. Today, I reseated all the cables, and power cycled the tape library. In my ssh session, I did this: $ sudo camcontrol devlist <ATA TOSHIBA DT01ACA3 ABB0> at scbus0 target 2 lun 0 (da0,pass0) <ATA TOSHIBA DT01ACA3 ABB0> at scbus0 target 10 lun 0 (da1,pass1) <ATA TOSHIBA DT01ACA3 ABB0> at scbus0 target 11 lun 0 (da2,pass2) <ATA

tape01 – old server; new purpose

This is tape01, the server to which the DELL TL4000 will be attached. At one time, it was my gateway/firewall/router. Of interest is the SAS card. You can see photos here. $ grep mfi /var/log/messages Dec 30 14:48:02 tape01 kernel: mfi0: <Dell PERC 6> port 0xd000-0xd0ff mem 0xfbec0000-0xfbefffff,0xfbe80000-0xfbebffff irq 19 at device 0.0 on pci3 Dec 30 14:48:02 tape01 kernel: mfi0: Using MSI Dec 30 14:48:02 tape01 kernel: mfi0: Megaraid SAS driver Ver

Installing net-mgmt/net-snmpd and getting it running

3 Comments / FreeBSD, snmp / By /

NOTE: If you are looking to configure net-mgmt/net-snmp for the first time, the latest article is Configuration of net-mgmt/net-snmp on FreeBSD. NOTE: IF YOU WANT TO GET IT WORKING, skip down to The Recipe. See also net-mgmt/net-snmpd wants /snmp/snmpd.conf for later versions of net-snmpd. I want to measure more stuff. I have catci running on some machines, but I have long neglected those stats. In response to my recent post on the FreeBSD

Deleting files from /usr/, breaking your system, then recovering

Yes, this was not fun. I took some notes, but not everything. Please read the notes if you plan on doing these foolish things. I was cleaning up /usr/src on a host which does not hold src. I looked and found: It was there that I knew I’d done the wrong thing. Trying snapshots Let’s look for snapshots, find one from a few minutes ago, and rollback to that. $ zfs list -t
