I use FreeBSD. I’ve used it since 1998. For me, it does good stuff, reliably, and predictably. The community is very supportive and helpful. That goes a long way when choosing your open source operating system. Included within FreeBSD, since FreeBSD 4.0 in March 2000, is a great tool for separating out services and to provide a virtualization strategy: jails. Some will argue that jails are not virtualization. I contend that it’s a […]

A few weeks ago, I moved some Bacula Volumes from one Storage Daemon to another. In fact, I was decommissioning the old bacula-sd and creating a new one. I copied all the Volumes over. Backups have been running smoothly ever since. However. Today I tried a restore. It failed. Without any useful diagnostic information. Here is what I have: After thinking for a while, I started to wonder if this was a database

I’m thinking about a Nagios check to let me know the status of various Bacula pools. As in, how many volumes are left, versus the maximum number of volumes permitted in this pool. Here is the bconsole command I would use: And here’s the command line bit which might work: I’ll ponder this a bit longer, and decide if I really want this monitored.

I’ve been building up a new server lately. Now I’m ready to move the tape library from the old host to thew new host. As I opened the new server to insert the existing SCSI card, I discovered that I needed a new SCSI card. It just would not fit. This is the card I was using under FreeBSD 8.4: ahc0: <Adaptec 2944 Ultra SCSI adapter> port 0xa800-0xa8ff mem 0xfb7df000-0xfb7dffff irq 20 at

If you’re using Suffusion and you just upgraded to WordPress 3.6, you may have to fix something manually. In my case, I’m on Suffusion 4.4.6. I’m sure suffusion will be upgraded soon, and I’ll direct them to this post just as soon as I get it out. If, after upgrading to WordPress 3.6, you see this message: Strict Standards: Declaration of Suffusion_MM_Walker::start_el() should be compatible with Walker::start_el(&$output, $object, $depth = 0, $args =
I’m in the process of moving a system from one server to another. Today, I’m going to try moving a jail using ezjail-admin archive. The two systems I am copying jails between these two systems: source: FreeBSD 8.4-RELEASE destination: FreeBSD 9.1-RELEASE-p4 I really am interested to see if this works. Creating the archive Best practice is to stop the jail. You can archive a running jail, but I content that you will get

Tonight I created a new jail, and later installed sudo into that jail. Then I tried to run sudo: $ sudo make install clean sudo: effective uid is not 0, is sudo installed setuid root? What? It is setuid: $ ls -l `which sudo` -rwsr-xr-x 1 root wheel 117112 Jul 26 17:08 /usr/local/bin/sudo I had no idea. wxs had the answer: mount points. Here is the problem, as revealed by this command in

I’ve been using Nagios for a while. I use it to monitor many things, varying from disk space to disk temperature. One of the packages I use for this is net-mgmt/nagios-check_smartmon. This code is getting out of date it seems. According to the timestamp at the top of the file, the last time it was updated was 2006-03-24 10:30:20. So it’s not surprising that it’s failing to work properly on a few cases.

After the zfs send, I had system/foo/bar, but I really just wanted system/bar. How do I fix that? mv(1) was my first guess. I was wrong. What I wanted was zfs(8) rename. Let me explain. After doing my: zfs send storage/compressed/bacula@2013.07.22:06:33 | mbuffer | ssh -t dan@10.5.0.20 ‘zfs receive system/usr/local/bacula/FromKraken’ I quite, correctly, wound up with system/usr/local/bacula/FromKraken, not the system/usr/local/bacula which I wanted. Here’s how I fixed that, but first, I took snapshots,

Today it finished. That ZFS send I started on Monday finally finished. Recap The original command was: # zfs send storage/compressed/bacula@2013.07.22:06:33 | mbuffer | ssh -t dan@10.5.0.20 ‘zfs receive system/usr/local/bacula/FromKraken’ That’s was the initial send of the filesystem. But more data has been added to it. So I take another snapshot, and send that: Send what’s accumulated since previous send # zfs snapshot storage/compressed/bacula@2013.07.25:08:20 And now I send the incremental stream: # zfs
