Prologue
I played adidas Originals Hide and Seek game several weeks ago in Facebook. The game was initially quite tough but I managed to answer all the puzzles correctly. And as I expected, I managed to become one of the winner and the gift that I won is adidas Originals Sennheiser CX 310 Earphone worth about RM195 – RM210.
The parcel was delivered by DHL,
Nice greetings by adidas Originals team,
The climax – adidas Originals Sennheiser CX 310 Earphone,
The earphone comes with 3 ear adapter set and nice carrying pouch,
Review
Technically it’s a good earphone, it meets my expectation: nice bass & noise isolation/cancellation. Good looking and cool design by adidas are the bonus features. But I have to admit it’s quite expensive, I don’t think I will buy it using my own money as I can also get cheaper earphone with same quality by Sony.
I know I already had a yellow/black sneaker but this time I have to admit that I seriously got a crush on adidas Kopenhagen,
adidas Kopenhagen Sunshine / Gum / Black
Wearing this sneaker with adidas Malaysia jersey and adidas jeans would be so awesome. adidasssssssssssssssssssssss!

There’s no more space available on VolGroup00 for me to create other filesystems. So, I want to reduce the space of /dev/VolGroup00/root so that I can create other logical volumes for /usr, /var, /tmp etc.
How can I reduce/shrink root’s logical volume? Here are the steps – I’m using RHEL 4 on VMware in this case,
Boot from RHEL 4 image and select "rescue" option. I chose to skip the rescue system from mounting my filesystems
Run pvscan + vgscan + lvscan
Run e2fsck with force option
Run resize2fs to reduce the filesystem (this is a pre-requisite before reducing the diskspace on logical volume level)
Run lvreduce to reduce the logical volume size and follow by lvdisplay command to see the change.
I just learned that there are several ways to change time zone setting in Linux from command line interface (I’m using Red hat Enterprise Linux in this case),
[root@localhost ~]# tzselect
Please identify a location so that time zone rules can be set correctly.
Please select a continent or ocean.
1) Africa
2) Americas
3) Antarctica
4) Arctic Ocean
5) Asia
6) Atlantic Ocean
7) Australia
8) Europe
9) Indian Ocean
10) Pacific Ocean
11) none - I want to specify the time zone using the Posix TZ format.
#? 5
Please select a country.
1) Afghanistan 18) Israel 35) Palestine
2) Armenia 19) Japan 36) Philippines
3) Azerbaijan 20) Jordan 37) Qatar
4) Bahrain 21) Kazakhstan 38) Russia

15) Indonesia 32) Nepal 49) Vietnam
16) Iran 33) Oman 50) Yemen
17) Iraq 34) Pakistan
#? 29
Please select one of the following time zone regions.
1) peninsular Malaysia
2) Sabah & Sarawak
#? 1
The following information has been given:
Malaysia
peninsular Malaysia
Therefore TZ='Asia/Kuala_Lumpur' will be used.
Local time is now: Mon Dec 19 14:47:51 MYT 2011.
Universal Time is now: Mon Dec 19 06:47:51 UTC 2011.
Is the above information OK?
1) Yes
2) No
#? 1
You can make this change permanent for yourself by appending the line
TZ='Asia/Kuala_Lumpur'; export TZ
to the file '.profile' in your home directory; then log out and log in again.
Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
Asia/Kuala_Lumpur
[root@localhost ~]# file /etc/localtime /etc/localtime: timezone data [root@localhost ~]# file /usr/share/zoneinfo/Asia/Kuala_Lumpur /usr/share/zoneinfo/Asia/Kuala_Lumpur: timezone data [root@localhost ~]# date Sun Dec 18 23:33:15 EST 2011 [root@localhost ~]# cp /usr/share/zoneinfo/Asia/Kuala_Lumpur /etc/localtime cp: overwrite `/etc/localtime'? y [root@localhost ~]# date Mon Dec 19 12:33:40 MYT 2011
So easy, eh :)
Tagged /etc/localtime, linux-change-timezone, tzselectSo, what you need to do after upgrading Linux kernel and/or applying GPFS fix pack?
Situation 1: Upgrading Linux kernel only
Previous Linux kernel: 2.6.18-274.3.1.el5
Current Linux kernel: 2.6.18-274.12.1.el5
After rebooted to new kernel, GPFS won’t be able to start due missing of GPFS portability layer
[root@kpgmedprod02 ~]# mmstartup
Tue Dec 13 15:26:41 MYT 2011: mmstartup: Starting GPFS ...
[root@kpgmedprod02 ~]# tail -f /var/adm/ras/mmfs.log.latest
Tue Dec 13 15:26:41 MYT 2011: runmmfs starting
Removing old /var/adm/ras/mmfs.log.* files:

[root@kpgmedprod02 ~]# mmgetstate
Node number Node name GPFS state
------------------------------------------
2 kpgmedprod02 down
What we need to do is these 4 simple steps: cd /usr/lpp/mmfs/src && make Autoconfig && make World && make InstallImages
Make sure kernel-devel package for running kernel is installed, otherwise we’ll hit this error:
[root@kpgmedprod02 ~]# cd /usr/lpp/mmfs/src && make Autoconfig && make World && make InstallImages cd /usr/lpp/mmfs/src/config; ./configure --genenvonly; if [ $? -eq 0 ]; then /usr/bin/cpp -P def.mk.proto > ./def.mk; exit $? || exit 1; else exit $?; fi Cannot find a valid kernel include dir make: *** [Autoconfig] Error 1
If everything is good, we won’t see any error. And we can start GPFS daemon,
[root@kpgmedprod02 ~]# mmstartup Tue Dec 13 15:31:35 MYT 2011: mmstartup: Starting GPFS ...
We can verify the result in GPFS log (/var/adm/ras/mmfs.log.latest),
Tue Dec 13 15:31:35 MYT 2011: runmmfs starting
Removing old /var/adm/ras/mmfs.log.* files:

And yes, GPFS state is now active,

Situation 2: Applying GPFS Fix Pack only
Current GPFS version (3.3.0-15),
[root@kpgmedprod05 ~]# rpm -qa | grep -i gpfs gpfs.gpl-3.3.0-15 gpfs.docs-3.3.0-15 gpfs.base-3.3.0-15 gpfs.gui-3.3.0-15 gpfs.msg.en_US-3.3.0-15
I’m going to install latest GPFS fix pack (version 3.3.0-18)
[root@kpgmedprod05 ~]# ls -lh gpfs.* -rw-r--r-- 1 root root 6.1M Dec 13 12:45 gpfs.base-3.3.0-18.x86_64.update.rpm -rw-r--r-- 1 root root 163K Dec 13 12:45 gpfs.docs-3.3.0-18.noarch.rpm -rw-r--r-- 1 root root 430K Dec 13 12:45 gpfs.gpl-3.3.0-18.noarch.rpm -rw-r--r-- 1 root root 55M Dec 13 12:45 gpfs.gui-3.3.0-18.x86_64.rpm -rw-r--r-- 1 root root 77K Dec 13 12:45 gpfs.msg.en_US-3.3.0-18.noarch.rpm [root@kpgmedprod05 ~]# rpm -Uvh gpfs.* Preparing... ########################################### [100%] 1:gpfs.base ########################################### [ 20%] 2:gpfs.docs ########################################### [ 40%] 3:gpfs.gpl ########################################### [ 60%] 4:gpfs.gui ########################################### [ 80%] You may start the GPFS GUI now by typing : /etc/init.d/gpfsgui start Alternatively, the GPFS GUI will start on reboot. 5:gpfs.msg.en_US ########################################### [100%]
Like Situation 1 above, we need to rebuild GPFS portability layer,
[root@kpgmedprod05 ~]# cd /usr/lpp/mmfs/src/ && make Autoconfig && make World && make InstallImages
Once done, bring up GPFS service,
[root@kpgmedprod05 src]# mmstartup Tue Dec 13 15:47:45 MYT 2011: mmstartup: Starting GPFS ...
Tadaaa, as expected everything is good,
[root@kpgmedprod05 src]# mmgetstate
Node number Node name GPFS state
------------------------------------------
5 kpgmedprod05 active
Situation 3: Upgrading Linux kernel and Applying GPFS Fix Pack
This actually a combination of Situation 1 & Situation 2, just rebuild GPFS portability layer again with this command:
cd /usr/lpp/mmfs/src && make Autoconfig && make World && make InstallImages
Conclusion
We need to rebuilt GPFS portability layer (command: cd /usr/lpp/mmfs/src && make Autoconfig && make World && make InstallImages) after upgrading Linux kernel and/or after applying GPFS fix pack.
