Here is the output for zfs-stats on slocum. This represents a 24 hour period. This server acts as my database server (MySQL and PostgreSQL), and runs bacula-dir, but does not store any backups locally. It also houses the dev copy of FreshPorts.

Here’s something to be aware of. Update your PostgreSQL client on your Bacula client if it is used for backing up the Catalog. Ngaios just told me: FILE_AGE WARNING: /usr/backups/bacula/MyCatalog.dump is 45125 seconds old and 0 bytes I looked at the backup job from earlier today: 28-Dec 08:15 bacula-dir JobId 195194: shell command: run BeforeJob “/usr/local/bacula/make_catalog_backup.new MyCatalog” 28-Dec 08:15 bacula-dir JobId 195194: BeforeJob: pg_dump: server version: 9.4.0; pg_dump version: 9.3.5 28-Dec 08:15 bacula-dir

Here is the output for zfs-stats on knew. This represents a 24 hour period. This server receives backups (via bacula-sd) and runs regression testing in various jails for the Bacula project. As a little side venture, it also loads up each of my backed-up databases.

NOTE: when upgrading a zpool, it may be necessary to also upgrade the bootcode for that disk (or disks). Be aware of this before proceeding. I know I have missed this step more at least once. Earlier today I was adding a new pool to the system. After creating the pool, the status showed this: Let’s upgrade that pool now Upgrading the pool Upgrading the pool is easy: Oh… Now what? I wasn’t

I haven’t tested this yet, but I’ve installed the hardware. The real test will come after a reboot and actual use of the new drives. NOTE: Although this claims to be creating a new ZIL (SLOG) do not believe it. In fact, stop reading right here. There is nothing of use below. What will they be used for? These drives are intended for ZIL (the ZFS Intent Log). This can speed up writes.

This post has been replaced by a newer one. For reference, the previous post on this server is still available. For future reference, this is the slocum server, which I use for various jails and services. This data was gathered adding increasing the RAM from 16GB to 32GB and adding two SSD to the previous configuration. This is my first ZFS system with more than one pool. Merry Christmas The filesystems, well, some
Backups are useless without restores. I’ve written a few posts about Nagios, my current monitoring tool of choice. Included with Nagios are a number of plugins and you can even write your own plugins. In this post, I’ll show you a shell script I wrote to make sure my backup files turn up where they should, when they should. In my case, these files are database backups, but the idea behind the script

This blog is powered by WordPress. When I first start blogging, few had heard the term blog. I hadn’t. I recall being asked, why don’t you use blogging software for The FreeBSD Diary. The answer was simple: it didn’t exist when I started. I am making headway on converting the diary to WordPress, and that might happen before the end of the year. Today, this blog got its very own FreeBSD jail. There

Postfix has been trying to tell me something: your configuration is wrong. Most cleverly, Postfix has been emailing me about this. The first email came on 22 Oct 2014. I ignored it. The second email arrived five days later on 27 October 2014: I recall looking around, but I didn’t do anything. I think I found an error in the logs but didn’t have time to fix it. A few days ago, another
