And so I’ve spent days and days, prolly weeks, to get rid some of the problems I faced in my FreeBSD. Currently running on version 8.0-RELEASE, I’ve upgraded almost all of my installed ports, and get my usb stick to work with the new usb stack. Everything works wonderful, stable and I’m a happy user.

Happy eh?

At least I thought so.

Today it crossed my mind to check how my hard disks are doing and to my surprise, one of the report came back with a failure alert:

Less than 24 hours? And I happened to be damn lucky to check on my disks today? Since day one I bought the hard disks, I’ve never really checked on it. Today I did, and I got this. Am seriously hoping that it’s just a false alarm (still am gonna do my backups).

And that is my around-2yo WD hard disk. My second WD hard disk. My first WD hard disk failed on me after running for less than a year. Jinx? Lol. Wait. This is not funny! Hmmmpphhhhhhhh..

Anyway, am too frustrated now. My hands are cold, my feet are cold, and all I could think of right now is doing a backup so that I could port my old system to a new hard disk. Which I have to buy..

Speaking of which.. another WD? Seriously I don’t know. Everyone is saying WD is the best, yet 2 of them died (well this one hasn’t died yet but already complaining) fast enough. Maxtor served me for a good 5 years or more, but the reputation isn’t that great either compared to other brands. Suggestion?

Quoted from StatsView README:

#####################################################

PREREQUISITES
————-

StatsView is written in Perl5, using the Perl Tk extension library. I recommend
that you use perl5.005_03 or later, and Tk800.014 or later, as StatsView has
been tested with these versions. You will also need the Tk::GBARR add-on
package for this version.

The graphing is done with gnuplot, and version 3.7 or later is required -
a copy can be found in the gnuplot_src subdirectory.

#####################################################

I already have Perl5 and gnuplot in my system, so I only need to install Perl Tk, Tk-GBARR and StatsView.

Install Perl Tk:

#apt-get install perl-tk

Grab Tk-GBARR from http://www.cpan.org/authors/id/SREZIC/. At this time of writing the latest version of Tk-GBARR is 2.08:

#fetch http://www.cpan.org/authors/id/SREZIC/Tk-GBARR-2.08.tar.gz
#tar xvfz Tk-GBARR-2.08.tar.gz
#cd Tk-GBARR-2.08
#perl Makefile.PL
#make
#make test
#make install

Grab StatsView from http://www.cpan.org/authors/id/ABURLISON/.

#fetch http://www.cpan.org/authors/id/ABURLISON/StatsView-1.4.tar.gz
#tar xvfz StatsView-1.4.tar.gz
#cd StatsView-1.4
#perl Makefile.PL
#make install
#./scripts/sv

Test StatsView using the example included:

#cd /path/StatsView-1.4/examples
#gzip -d sar.txt.gz
#../scripts/sv sar.txt

It worked wonderfully using the sar output sample.. but I couldn’t get it to display any graph using my collection of sar output, both in binary and text formats. At this point am still not sure why it kept on complaining that my output file is invalid.

They are valid AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAa!!!

Now what am I supposed to tell my boss?

“Hi boss.. remember the Linux server performance data that I promised last week? I don’t have it.”
“How come?”
“I have it, but I don’t have it in a pwetty graph format like I pwomised.”
“Well it’s okay you can pass me the raw data.”
“It’s in binary.”
“What?”
“Uh.. you know there are 10 types of people in the world: Those who understand binary, and those who don’t…”
“You don’t have anything to present, do you?”
*GULP*

Today I decided to install Sun VirtualBox on my FreeBSD 7.1/amd64. The installation from ports is straightforward as usual.

#csup -g -L2 /etc/ports-supfile
#cd /usr/ports/emulators/virtualbox
#make install clean

I got stuck when it failed to fetch this file Dev86src-0.16.17.tar.gz.

#wget ftp://ftp.freebsd.org/pub/FreeBSD/ports/distfiles/Dev86src-0.16.17.tar.gz
#mv Dev86src-0.16.17.tar.gz /usr/ports/distfiles/
#make install clean
#hash -r ; ldconfig

Mount proc:
#mount -t procfs proc /proc

Load vbox driver module:
#kldload vboxdrv.ko
#kldstat | grep box
13    1 0xffffffffab46a000 3fb0e    vboxdrv.ko

Launch vbox from menu or command:
#VirtualBox

Done.

This could be one of the bestest news I’ve heard in months!!

Excerpt from miwi:

“Today Virtualbox was committed to the FreeBSD ports tree. After a lot of work we had a good discussion today about how stable Virtualbox is, and after the CTF with take6 we got a lot of good feedback, so it was time to commit.”

Read it here.

Woohoo!!

One of my recent project was to configure Edge load balancer on 2 servers in high availability (HA) environment. I rarely do Edge, but the configuration is pretty straightforward. In my past projects, Edge implementation has always been in separate boxes, which is easier compared to collocated setup. In this post I’m going to share my configuration for edge dispatcher (MAC forwarding) that resides together with web server (I’m using IHS) and WebSphere. Each server will use 1 IP address for both web server and dispatcher. The configuration is almost the same, but there were few issues that I encountered and I hope this post will be of help to those who are dealing with Edge dispatcher as well.

For typical setup of Edge load balancer servers that do not reside in the same box with web servers, the general rules are:
- Primary Edge – cluster IP aliased to its NIC.
- Standby Edge – cluster IP aliased to its loopback.
- Web Servers – cluster IP aliased to loopback.

These rules hold the same in collocated environment:
- Primary Edge – cluster IP aliased to its NIC.
- Standby Edge – cluster IP aliased to its loopback.

Double collocated HA edge.

Say I have the following:
Cluster IP – 192.168.10.10
Cluster port – 8080
Primary Edge – 192.168.10.20
Backup Edge – 192.168.10.21

goActive script:

This script will remove the cluster IP from loopback and alias it to the NIC.

#!/bin/ksh

CLUSTER=192.168.10.10
LOOPBACK=lo0:1

ifconfig $LOOPBACK 0.0.0.0
dscontrol executor configure $CLUSTER

goStandby script:
This script will remove the cluster IP from NIC and alias it to the loopback.

#!/bin/ksh

LOOPBACK=lo0:1
CLUSTER=192.168.10.10
NETMASK=255.255.255.192

dscontrol executor unconfigure $CLUSTER
ifconfig $LOOPBACK $CLUSTER netmask $NETMASK up

goInOp script:
This script will remove the cluster IP from all devices (loopback and NIC).

#!/bin/ksh

CLUSTER=192.168.10.10
NETMASK=255.255.255.192

dscontrol executor unconfigure $CLUSTER
ifconfig $LOOPBACK $CLUSTER netmask $NETMASK down

The normal method to test if the high availability works smoothly is by plugging out the network cable off the edge server. I would tail the root mail (/var/mail/root) at the same time, so I could see which HA script has been triggered when the network is interrupted. Another method is to bring down the server, by rebooting it or shutting it down. With reboot you’ll only have a short time span to monitor the failover in action, but of course this depends on how long your servers take to start up.

But since this is a collocated environment, if I were to opt for either the described testing methods, I wouldn’t be able to see if the dispatcher balances all requests to both web servers accordingly (in my case I’m using the round robin algorithm). So what I did is, I manually stop the executor so that failover occurs. Note that stopping the dsserver alone won’t trigger the HA scripts. Actually it is not necessary to stop the dsserver. Well to be honest even if it’s not a collocated environment, I normally test the HA failover by stopping the executor, since normally am working remotely and plugging out the cable requires me to get the help of the sys admins. So might as well test if its really working before going through all the hassle.

One of the problem that I encountered was instability. Sometimes the dispatcher will run in the right mode (active | standby), but most of the time both will run as active. It was very unstable, no certain pattern that I could track. Even worse, sometimes when I tried ro run the dispatcher as a standalone lb, all of the incoming requests will be routed directly to the web server, skipping the dispatcher completely. I was stuck with this problem for several days when I finally figured out what the culprit is.

The ibmlb module.

Everytime when the executor is stopped, the ibmlb module will be unloaded. Everytime when the executor starts, the ibmlb module will be loaded to the kernel. I’m lucky that I have dmesg on both servers, so based from dmesg, this is how it should looked like whenever you stop and start the executor:

ibmlb DLKM successfully unloaded
ibmlb DLKM successfully loaded

But what happened was, when I stopped the executor, the ibmlb was not unloaded. The status was busy, and I’ll have to unload the module explicitly.

ibmlb DLKM successfully unloaded
ibmlb DLKM successfully loaded
ibmlb version is 06.01.00.00 – 20060515-232359 [wsbld265]
WARNING: moduload : module is busy, module id = 14, name = ibmlb
WARNING: moduload : module is busy, module id = 14, name = ibmlb
WARNING: moduload : module is busy, module id = 14, name = ibmlb
WARNING: moduload : module is busy, module id = 14, name = ibmlb
WARNING: moduload : module is busy, module id = 14, name = ibmlb

I’ve not seen anything like this before (I used to configure dispatcher on AIX servers). Consider the following test cases (arp table checked from a different server that resides on the same segment):

TEST 1.
1) Primary active, Backup standby. Cluster IP belongs to Primary.
2) Primary down, Backup goes active. Module ibmlb is UNLOADED successfully on Primary. Cluster IP belongs to Backup.
3) Primary up in active mode, Backup goes standby. Cluster IP belongs to Primary.

TEST 2.
1) Primary active, Backup standby. Cluster IP belongs to Primary.
2) Primary down, Backup goes active. Module ibmlb is busy and still LOADED on Primary. Cluster IP belongs to Backup.
3) Primary up in active mode, Backup stays active. Cluster IP belongs to Primary, but all requests will skip dispatcher and go straight to the web server.

TEST 3.
1) Primary active, Backup standby. Cluster IP belongs to Primary.
2) Primary down, Backup goes active. Module ibmlb is UNLOADED successfully on Primary. Cluster IP belongs to Backup.
3) Primary up in active mode, Backup goes standby. Cluster IP belongs to Primary.
4) Backup down. Module ibmlb is UNLOADED successfully.
5) Backup up, running in standby mode.
6) Backup down. Module ibmlb is busy and still LOADED on backup.
7) Backup up, running in active mode (remember that Primary is also in active mode too). Cluster IP belongs to Backup, but all requests will skip the dispatcher and go straight to the web server.
8 ) Backup down. Module ibmlb is busy and still LOADED on backup. Explicitly unload the module using kcmodule command until it gets UNLOADED. Cluster IP belongs to Primary.
9) Backup up, running in standby mode.

Most of the time I won’t be able to unload it right away, until I let the server ‘rest’ for about 15 – 20 minutes, before trying to unload it again. Rebooting the server will always solve this problem (the module next state is unused). Am not sure if there’s a way to force a module to be unloaded though. As far as I know there’s no force flag for kcmodule.

I was fooled several times since I tested the splash page of the web servers from my Opera browser. I was on a different subnet, so I guess there must be a switch/router in between me and the edge servers. At times, even when the cluster IP is aliased to the Primary Edge, my browser will point to the Backup Edge since the ARP cache was not refreshed. It was so annoying since this will affect the cluster report. The rest of the testings were done by running a browser from a different server but belongs to the same subnet. At least I could clear up the ARP cache manually if I have to.

Okay probably this is my browser problem, but testing the splash page with Firefox sucks. It kept on hitting the splash page even after I’ve stopped both web servers, and cleared up the cache. It was alright with Opera though. What gives?

By the way I’m using Edge v6.1. If you check out the Edge Fixpack page here, you’ll notice that there is no patch for HP-UX. Not a single patch. Is IBM trying to say something? Don’t use Edge on HP-UX, perhaps? Lol. Anyway, IBM packed me a patch (6.1.0.35), but still it didn’t address the module issue. Am not sure if I could call it a patch though, it’s more like an installer since I had to reinstall everything.

Thanks to Robert Brown from IBM for assisting me on this ‘false alarm’ panic attack (initially I thought it was a network issue).

Yea, there has been a lack of update. I was busy with WebLogic, and Devin.. oh well, he only writes material that meets a certain literary and relevancy standard and he is not that prolific. Lol. Guess you’ll never find him writing anything that will be tagged as rant

Few things happened last week..

Weblogic completed:
Am done with the project last week, which is cool. Haven’t gone through the UAT session with the users yet, so until they say “All’s good”, guess I’ll have to keep my fingers crossed. Weeee!!!!



I lost my handphone:
Yes, my cheap handphone. I can’t believe someone would want to steal it. I bought the handphone for about 300 – 400 bucks, so am surprised that someone would be so keen to steal it. How much does it worth really? 2 small packets of weed? Am not bothered about the phone. Well alright, I am bothered, because it costs money. But what I care the most is the data inside the phone. My contacts, my messages, heck I even have a few audio clips of my cat purring recorded with that phone. Oh well. Fuck you, thief.

Medical checkups:
I had a couple of medical checkups performed last Tuesday and Thursday. Last Tuesday I got all wired up for the holter monitoring test. It was something like a 24 hours of ECG (electrocardiogram) to monitor the electrical activity of my heart. I couldn’t take showers during the procedure because it’ll damage the device. So yeah, am pretty happy with the fact that I don’t have to shower and not feeling guilty about it. Am just plain lazy sometimes.

And last Thursday, I got up very early in the morning and headed to the General Hospital to get my brain checked. It was a quick EEG (electroencephalography), prolly around 20 minutes where I had to blink my eyes numerous times, with bright light flickered directly on me for a few minutes and inhale/exhale profusely for 5 minutes which was tiring since am asthmatic. And oh my, I looked horrible with my hair glued on with all the wires. And I looked even worse after the guy pulled them out. I looked like a woman who is trying too hard to impress a guy by applying extra hair gel. You know the type of hair gel that will make your hair hard and stiff? Gah. I hate it.

I’ll be getting the results this April. I hope everything will be fine, since am always fine, and anyway I agreed to go through all of these medical procedures because my sister told me to. Nothing serious.



FreeBSD upgrade:
Yeah, finally! Upgraded to 7.1. I did it last Saturday, and I was thinking to update this blog on Sunday, but guess what, the update went fine until suddenly I failed to start the X server. Hmmm.. now that’s weird, because this was not the first time I did a FreeBSD upgrade, plus, this was just a minor version upgrade, so what could go wrong? Building world, kernel and installing them went perfectly well. I didn’t forget to run mergemaster, the machine booted up well. Spent a day changing the theme, and all of the sudden it failed (yeah, ironically it failed after I spent the whole day beautifying my desktop, why didn’t it fail sooner?). I realized that it failed just after I ran portupgrade to upgrade my Opera and Firefox. Probably the modules are not synced, am not sure.

I spent the next 48 hours running portupgrade numerous times, until I finally decided to rebuild perl, xorg and xfce4. But to my surprise it failed. I reinstalled my xfce4 and its gang one by one, so they’ll all run on the same version. Reboot the machine and voila, am back. Still, some of my installed packages are broken, so I had to fix them.

So they say, if it ain’t broken, don’t fix it. I could’ve just stick to FreeBSD 7.0 and save the 48 hours from the agonizing pain of troubleshooting my machine. But seriously, it was worth it. The performance is so much better, XFCE 4.6 is brilliant with more new features and yes fellas.. flash 9 works

He got engaged:
Yes, he finally got engaged. AmazingCongratulations.

So much of his Nazi comment that ruffles the feathers of GNOME community last time.

I have always been a loyal user of XFCE4, but if I had my druthers between Gnome and KDE, I’d prefer Gnome. KDE is nice, I love some of KDE apps, but imho, it’s kinda bloated. Very pretty, way prettier than Gnome, but bloated. But of course, I’d go for Enlightenment if I want some real fancy stuff on my desktop.

Anyways, am not any DE/WM fanatic. I just love to keep my desktop clean and minimal.

I lol’ed.



Source: Q&A: Linux founder Linus Torvalds talks about open-source identity

I wish.. lol.

Am very new to weblogic, so am pretty excited to try it on my FreeBSD at home. Well ok, I just managed to install it, but couldn’t get it run. Bleargh. The problem is with the LD_LIBRARY_PATH I think. There’s no native directory under <WL_HOME>/server, so it’ll complain about the missing path when you try to start the domain or node manager. Pfftttt. I’d love to know how to fix this

But anyways, here’s how to install WebLogic 10g on FreeBSD 7. Just installing it, but it doesn’t work lol. I don’t know why I even bother writing this.

1 – FIrst of all, download the installer from the oracle website. Choose HP-UX as the operating system as that’ll provide you with a generic jar installer.
http://www.oracle.com/technology/software/products/ias/htdocs/wls_main.html

2 – While it’s downloading, install eclipse from the port.
cd /usr/ports/java/eclipse && make install clean

3 – Install eclipse WTP. Get it from here:
http://www.eclipse.org/downloads/download.php?file=/webtools/downloads/drops/R2.0/R-2.0.3-20080710044639/wtp-R-2.0.3-20080710044639.zip

Place the zip file at /usr/local and unzip it. It’ll place all the extracted files in the right directory.

4 – After you’re done with eclipse, you’re ready to install weblogic. Am performing this as a non root user.

I use diablo java, so running java -jar server103_generic.jar alone will not work.

My java -version:
java version “1.5.0″
Java(TM) 2 Runtime Environment, Standard Edition (build diablo-1.5.0-b01)
Java HotSpot(TM) 64-Bit Server VM (build diablo-1.5.0_07-b01, mixed mode)

So execute the installer using sun jdk directory to get it running:
/usr/local/jdk1.6.0/bin/java -Dos.name=unix -jar server103_generic.jar

You’ll have to specify the Dos unix name, else you’ll get the insufficient disk space error, which is very annoying when you actually have tons of free space. You may get lucky with this and the installation will end successfully. As for me, it stuck at 74% while creating the sample domain.

$ /usr/local/jdk1.6.0/bin/java -Dos.name=unix -jar server103_generic.jar
Extracting 0%……………………………………………………………………………………….100%

The error was out of memory exception, so I decided to reinstall it. But first I have to uninstall it first since weblogic detected that it has already been installed at the target directory.I run the installer with the following command:
/usr/local/jdk1.6.0/bin/java -Xmx2G -Dos.name=unix -jar server103_generic.jar

Installation complete!

Alright, now the installation is done, you might wanna try to start the sample domain.

Ahah! Now this is the part where I got unlucky.

It complains that the port is being used, when it’s not! Hmmmmphhhhh!

Well actually there are other errors came out before that but am too lazy to look at it. Lolz.

Now if you try to create a domain, you’ll get the shared library path error:

./config.sh: Don’t know how to set the shared library path for FreeBSD.

Same goes if you try to start a node manager.

Ah well.. think I’ll spare some other time playing around with this. Doing weblogic makes me miss websphere. Lol.

I learned my lesson the hard way. Last 2 years I bought a 120gb WD hard drive and used it for about 6 months before it suddenly died on me. 6 months, it was still covered by the warranty, but I chose not to return it for an exchange of a new one. I have tons of data inside but out of all data, I just need prolly around 30% of it. The rest, I can say goodbye with tears in my eyes. I still have the hard disk, kept nicely inside my wardrobe. When I have the chance, I’ll bring it back to live!

I love Maxtor hard drive. I still have one old Maxtor hdd that I’ve been using for almost 8 years running. In fact I used to have 2 of them. One has failed, but it is completely acceptable since it has served me for over 6 years.

Currently at work am preparing backup scripts for some servers. I find that backing up the entire directory of windows virtual machine is kinda annoying. Am thinking of what would be the best way to shutdown windows without using the force flag? Urgh. I wish I can just init 0.

At home I use a simple script that I wrote to backup directories. Basically what it does is it checks the content of both source and target directories, and any files/directories that are not available at the target location will be copied, creating a duplicate copy of the original directory. It’ll also generate a log (diff.log) to record what files that have been copied over. I use it to backup log files, nothing in giga size.

The output of diff.log will be something like this:
