Using the Compaq Storage Works MSL5026 Library

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

I am fortunate to receive donations. In the early days, it was a 386 desktop. Later, it was SCSI drives. Recently, it’s been tape libraries. A Bacula user in Europe donated an Overland DLT-8000 tape library in 2012 and paid for shipping to me. At BSDCan 2013, I was fortunate to pick up an Compaq StorageWorks MSL5026 SDLT tape library and it has sat unused. It’s dead Jim A few weeks back, the […]

I’ve noticed that the smartd output has changed. It’s not parsing the results correctly.

Bacula: indexing on media.lastwritten

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

I wrote this nearly a year ago, but did not publish it then. Tonight I found this query running, so I tried an explain analyse on it: That’s 10 seconds. Add an index: bacula=# create index media_lastwritten_idx on media(lastwritten); CREATE INDEX Run the query again: Forgive my math, but that’s over 10,000 times faster now.

Script for listing the latest ZFS snapshot – starting place for Bacula backups

Leave a Comment / Backups, Bacula, ezjail, FreeBSD, Jails, ZFS / By /

This post has it all: backups deduplication snapshots ZFS Bacula ezjail Backups are essential for proper sanity, or at least, a reasonable facsimile. I strongly believe that doing backups right is the only way to backup. Go big or go home. I’ve been converting all my servers to ZFS. I like ZFS for many reasons, and I’m going to list two: data integrity snapshots In this case, instead of backing up the entire

FreeBSD jails on non-routable IP addresses

Leave a Comment / FreeBSD, Jails / By /

One of my goals with the server I’m setting up is putting non-public services into jails with non-routable IP addresses. Today, I’ve been working on getting PostgreSQL into a jail. The problem I have been grappling with is not putting PostgreSQL into a jail but routing. It took me a while to figure out where I was going wrong. Turns out, it was my NAT rules and, perhaps, my IP address strategy. The

Accessing FreeBSD Jails over OpenVPN

Leave a Comment / FreeBSD, Jails, OpenVPN / By /

With this new server, I am taking a new approach. Each jail will have at least three IP addresses: The public IP4 address, used by internet facing services (e.g. http or https) The public IPv6 address, similar to the above A VPN address, used for system administration and private services (e.g. nrpe) In this article, I will assume you are familiar with ezjail, FreeBSD jails, basic networking, OpenVPN, and ZFS. That is, this

Bootstrapping a new FreeBSD jail host as an Ansible node

6 Comments / ansible, FreeBSD, Open Source / By /

A few days I configured a new server to be an Ansible node. This will allow my Ansible configuration tool to configure and install software. Installing Ansible and getting it running is not covered by the post. All I show here is how I got a remote server ready to be configured by Ansible. The server in question was running FreeBSD 9.2 with ZFSRoot. Preparing the client for configuration by Ansible Key to
