As recently written, I have acquired a tape library with a 15-tape magazine. It contains a DLT-8000 tape drive which, although it is no longer state-of-the-art, is a step up from the DLT-7000 I am currently using. Today, I will try using this unit for the first time. I’ll do a simple write, try changing […]

Right after getting my SCSI cable problems fixed, I was all set to run some Bacula jobs. They immediately started failing: 27-Nov 12:59 bacula-dir JobId 112458: Start Copying JobId 112458, Job=CopyToTape-Diff.2012-11-27_12.58.05_08 27-Nov 12:59 bacula-dir JobId 112458: Using Device “DTL01” 27-Nov 12:59 kraken-sd JobId 112458: Ready to read from volume “DiffAuto-2357” on device “MegaFile” (/storage/compressed/bacula/volumes). 27-Nov

This is the sixth in a series of articles on my migration to WordPress. In this post, I’ll talk about how I enabled the old URLs. This is important only if you want the ‘old’ content to be found. This is especially important if your website is well established. People will have links to your

I’m sitting in the The Warden – FreeBSD and Linux Jail Management talk at EuroBSDCon 2012. He has mentioned two things, so far, that give me ideas. Evil ideas. Put each jail in a different ZFS data set – this may be useful for my jails running Bacula regression testing Schedule cron jobs to do

This is the first in a series of articles on my migration to WordPress. I have another diary (The FreeBSD Diary). I’ve been running it since 1998. More than once I’ve been asked why doesn’t it use some blogging package. Well, I didn’t know of anything back then, and cobbled together my own solution. The

Last night, I found that I had a number of unused ZFS snapshots. I decided to destroy some of them. The first destroy locked up the system. Nagios reported everything was dead. I remotely power cycled the system. After it came back, I noticed that a scrub was in progress. This had not been initiated

OK, let’s compare the two snapshots, one taken today, the other taken on Monday. [dan@ngaio:/usr] $ sudo du -c -d 1 . Password: 4 ./.snap 62760 ./bin 37520 ./include 93068 ./lib 184 ./libdata 35384 ./libexec 75109696 ./local 37708 ./sbin 102480 ./share 1103840 ./src 250268 ./compat 376 ./games 4 ./obj 71082728 ./home 3584112 ./ports 4 ./tmp
It seems the /usr partition on my dev box is filling up. But I’m not sure what is eating up the space. So let’s take a snapshot of the space and compare it later. [dan@ngaio:/usr] $ sudo du -c -d 1 . Password: 4 ./.snap 62760 ./bin 37520 ./include 93068 ./lib 184 ./libdata 35384 ./libexec

Recently, I was moving some jails from one server to another. First, I created the jail using the -x switch, which indicates the jail already exists, don’t create it, just add entries for it: # ezjail-admin create -f bacula -x mysql41.example.org 10.35.0.100 Warning: Some services already seem to be listening on IP 10.35.0.100 This may

As part of my magical Bacula website, I wanted to know when my tape drive required a cleaning tape. It appears that smartctl will reveal this information: [dan@kraken:/usr/home/dan] $ sudo /usr/local/sbin/in/smartctl -d scsi -x /dev/nsa0 Password: smartctl 5.39.1 2010-01-28 r3054 [FreeBSD 8.2-STABLE amd64] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Device: DEC TZ89
