Moving zfs datasets / filesystems around

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

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, […]

zfs send | zfs receive; finally finished

Leave a Comment / File Systems, FreeBSD, ZFS / By /

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

zfs send from old file server

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

Earlier today, I started a zfs send | zfs receive between the old file server and the new file server. It won’t finish until early morning tomorrow. [root@kraken ~]# 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’ Pseudo-terminal will not be allocated because stdin is not a terminal. in @ 54.9 MB/s, out @ 54.9 MB/s, 47.6 GB total, buffer 100% full Why mbuffer? Because it shows me some

Gateway getting old; File server getting full

Leave a Comment / FreeBSD, ZFS / By /

My gateway is dying. My file server is getting full. Over the past few weeks, I’ve been dealing with aging infrastructure. My development server started acting up and was showing signs of age. This aging desktop box contained 80GB HDD, which means it’s probably 6 or 7 years old. That’s getting on in age. It’s been replaced by a much gruntier server. After completeing that work, I have to consider my gateway, which

Using compression with PostgreSQL’s pg_dump

4 Comments / databases, Open Source, PostgreSQL / By / /

I attended a few of the talks at PGCon 2013 last month. One talk, for which I took several notes and made a few choice tweets. The main one I’m following up on is using the -Fc option on pg_dump. It was during Magnus Haganders’ talk on PostgreSQL Backup Strategies that I posted that tweet. In the two weeks since that talk, I managed to do some testing. Let’s have a look at

nagios – check_ping CRITICAL – You need more args!!! Could not open pipe:

2 Comments / Jails, Nagios / By /

I’ve been moving some services around lately. A server is dying and I need to move stuff off it. Today I managed to move Bacula and Nagios onto a new server. After a short bit of struggle, I had just one service check that was failing: check_ping. Here’s the example: $ /usr/local/libexec/nagios/check_ping -H bast.example.org -w 3000.0,80% -c 5000.0,100% -p 1 CRITICAL – You need more args!!! Could not open pipe: Google searches did

ezjail – renaming, moving, and renumbering

1 Comment / Jails, Open Source / By /

ezjail is my tool of choice for managing jails. I’ve been using it since 2008. Today, I want to do something which ezjail won’t do for me, but will allow me to do. I created a bunch of jails for a Bacula tutorial at BSDCan. Now that I have that server safely home again, I need to add more services to this jail server. My main development machine is acting up. It is

Restricting IP addresses to specific databases

1 Comment / Open Source, PostgreSQL / By / /

Sometimes, you don’t want just anyone talking to your database. In fact, sometimes, you don’t want anyone accessing your database except very specific applications. In this case, I am setting up about 20 databases, each one dedicated to a specific use, and to be accessed only from one IP address each. In this post, I’ll talk about how I first set this up with pg_hba.conf, and then how I altered it to be

Creating a ZFS-only box – the first look

3 Comments / File Systems, FreeBSD, ZFS / By /

I’m about to start setting up a ZFS-only box using FreeBSD 8.2. There will be no UFS volumes in this system. Every previous server I have set up has always booted from a gmirror’d UFS system first, then mounted a ZFS array. This time, everything will be on ZFS. I’ve described this server previously when I first chose the parts back in January. Now, the push is on to get this system installed

The hardware is ready. What tests to run?

19 Comments / Backups, Disks, File Systems, hardware, ZFS / By /

I think I’m now at the point where I have all the hardware assembled and it’s ready for testing. Now I’m trying to determine what set of fio tests to run. If you know of a set of standard tests, or just have some of your own, please let me know in the comments. The hardware The disks I have assembled are all available via the LSI 9211-8i. The basic hardware specs are:
