Installing and configuring Graphite with Collectd on FreeBSD
Using Graphite for a smidgen blog like mine is definitely an overkill and Munin fits much better but I wasn’t able to confront my curiosity. So that’s why this post. Before I start, I’d like to mention that even if I’ll be speaking about my endeavor with Graphite on a system running FreeBSD 10.0-RC5, the […]
Another web server powered by FreeBSD
During the last couple of days I’ve been migrating data and various configurations from my old Ubuntu server to a new one which is running FreeBSD 10.0-RC5 now.
Upgrading FreeBSD 9.2 to 10.0-RC4 on Rackpsace’s instance
In reality it turned out to be a fairly straightforward procedure: This is crucial. You must save XENHVM config before the upgrade otherwise you won’t be able to re-build the kernel which is required to bring the network up. # cp /usr/src/sys/amd64/conf/XENHVM /root/amd64_XENHVM # cp /usr/src/sys/i386/conf/XENHVM /root/i386_XENHVM Perform the upgrade as usual and just follow […]
Grow root ZFS pool online under FreeBSD 9.2 using Rackspace’s instance
If you opted for a FreeBSD instance on Rackspace and chose standard configuration then you’ll end up with 512MB of RAM and 20GB of space. That’s ok for the starter but eventually you’d need more one day and will upgrade RAM to 1GB for example. With this upgrade your disk will grow upto 40GB but […]
Never make plans but I’ll try
From New Year’s Resolutions for SysAdmins presented by USENIX I have picked just three for myself: “Gather more metrics and become a data driven IT team.” “I will not ever again work for a cheapskate business owner who cannot, or will not, pay me a fair rate.” “Learn to be a better coder.” The latter […]
How to say “yes” to pkgrm
If you got bored pressing “y” every time you delete a package and pkgrm asks its “Do you want to remove this package? [y,n,?,q]” question, there is a very easy solution: # yes | pkgrm package1 package2 … package3 Has saved me a lot of time.
ruBSD 2013 Conference
Just noticed that the registration for ruBSD 2013 Conference (translated) has been closed. So happy I applied earlier and will have a chance to listen to Theo de Raadt, Konstantin Belousov, Henning Brauer and other BSD starts in person.
Why doesn’t Solaris SMF aware service start on boot?
A quick hint on how to find a possible root cause why a newly imported service doesn’t auto start on system reboot. So… You’ve just imported service’s manifest, rebooted the system and noticed the service is still in the offline state: svccfg import service_manifest.xml init 6 svcs service_name STATE STIME FMRI offline 15:55:52 svc:service_name:default A […]
Back to school with Coursera
There are two courses that have been recently relaunched at coursera.org: Machine Learning Game Theory Both are very interesting and highly recommended to attend. So don’t think twice and join the class whilst they are in their first week only. Hopefully I will have enough time to complete both of them.
Matching Oracle ASM disks names with the physical devices
Quite often it’s required to find a physical device which backs up ASM disk. The easiest way a Linux administrator could accomplish that is by using oracleasm command (of course, if ASMlib was used to create them): # oracleasm listdisks ASMARCHIVE1 ASMARCHIVE2 ASMARCHIVE3 ASMDATA1 ASMDATA2 ASMDATA3 OCR1 OCR2 VOTEDISK1 VOTEDISK2 VOTEDISK3 # oracleasm querydisk -p […]
