HPUX LVM vg00 mirror

2011-08-01T12:26:00.003+08:00

vg00 originally mirrored with disk9_p2 and disk8_p2. Want to get rid of disk9 and disk8 and use disk6 and disk7.

Luser Attitude Readjustment Tool

2011-01-23T04:40:00.001+08:00

lart(8)         lart(8)

NAME
       lart  - Luser  Attitude Readjustment Tool - use a lart to
       adjust lusers' attitudes

SYNOPSIS
       lart [ -use tool ] [ -bBfFgklp ] 

DESCRIPTION
       lart adjusts the attitudes of those pesky, clueless people
       who  rely  upon their  admins for everything from picking
       their mice off of the floor to turning on their monitors;
       namely, the  luser(8). Running lart with the appropriate
       arguments will cause  the  specified  luser  to run  away
       screaming in agony.  Alternatively, you can make the luser
       buy you a beer, after killing all of their processes.

Solaris 10 x86 on VMWare

2011-01-23T00:15:00.002+08:00

MacOSX 10.6.4 running on AMD Phenom X2 555

2011-01-18T10:58:00.011+08:00

Finally I managed to install 10.6.4 on my AMD Phenom X2 555 system with Asus M4A88T-V EVO/USB3.

The problem that I'm facing right now is to get my onboard AT HD4250 to work, at least to change resolution to 1920x1080. So far I found out that 4250 is NOT supported. Tried installing RadeonHD kext but somehow couldn't get it to work. Will continue to work on this later on.

USB 2.0 seems to work (haven't check whether it's 1.1 or 2.0 - later), USB 3.0 not tested (i don't have USB 3.0 device), Firewire not tested

Anyway, I'm using retail DVD 10.6.4, created USB install disk using nawcom method in Ubuntu, repartition my 2TB to make root disk < 1TB (I learned that OSX cannot boot if root disk is more than 1TB). Install Chameleon RC4 and legacy kernel 10.6.4.

Haven't test my onboard audio after install VoodooHDA kext but I got no sound via HDMI. Next is to fix my GFX, and then to get audio to work via HDMI (if possible, haven't research thoroughly yet)

Final step is to install XBMC and Jdownloader :) That is my sole purpose.

Complete hardware specs:
AMD Phenom X2 555 BE
Asus M4A88T-V EVO/USB3 (onboard ATI HD4250, onboard ALC892 8-channel HD Audio, ..)
Seasonic 520W modular PSU (not related to OSX but what the heck :P )
Silverstone LC17B
750GB Samsung HDD (running Ubuntu 10.10)
2TB WD Green Ed. (running MacOSX 10.6.4 - not yet finished completely)
Connected to LG LCD LD420 via HDMI
Asus USB wireless 54g stick (can't remember the model and haven't configure/test in MacOSX as well)

MacOSX 10.6.4 ISO/DVD offset

2011-01-18T09:52:00.011+08:00

dump everything in DVD to ISO (change /dev/sr0 to your DVD device):
# cat /dev/sr0 > macosx_10.6.4_install.iso

find your offset (it is gonna take quite some time, so be patience):
# hexdump -C macosx_10.6.4_install.iso | grep "48 2b 00 04"
31b4b400 48 2b 00 04 80 00 01 00 31 30 2e 30 00 00 00 00 |H+......10.0....|

convert 31b4b400 to decimal and minus 1024

example:
$ echo `printf "%d\n" 0x31b4b400` - 1024 | bc
833925120

so:
10.6.4 ISO/DVD offset: 833925120

maybe you can try to find your offset if you're using DVD (haven't try this one):
# hexdump -C /dev/sr0 | grep "48 2b 00 04"

then mount your ISO:
# losetup -o 833925120 /dev/loop0 ./mac osx_10.6.4_install.iso
# mkdir /media/osx-dvd
# mount -t hfsplus /dev/loop0 /media/osx-dvd/

to unmount:
# umount /media/osx-dvd
# losetup -d /dev/loop0

you might ask, why "48 2b 00 04" and why minus 1024? refer here: http://www.64lines.com/mounting-hfs-plus

Finding an HSF+ Partition

How do you find an HFS+ partition? Well according to docs at http://developer.apple.com/technotes/tn/tn1150.html#VolumeHeader an HFS+ partition starts with 1024 reserved bytes for boot code followed by the VolumeHeader structure. The first 4 bytes of the VolumeHeader structure are a signature and a version number. Essentially "H+" followed by version 4 (or HX followed by 5 for HFSX). Therefore we are looking for the following hexadecimal sequence within the file: "48 2b 00 04" (or "48 58 00 05" for HFSX).

Cron (solaris) "bad user" error

2011-01-13T15:30:00.002+08:00

cron (solaris) "bad user" error message in /var/log/cron
--------------------------------------------------------

Cron needs to be able to access a shell as the cron user in order to
do its thing. The easiest work-around for this is to edit the
/etc/shadow file and change the *LK* to *NP* for the affected
accounts.

vxrestore / vxdump

2011-01-11T18:00:00.001+08:00

# vxdump 0fu /dev/rmt/0m /var ; dump vxfs file system /var to tape /dev/rmt/0m using level 0 and update /var/adm/dumpdates

# vxrestore tf /dev/rmt/0m | grep eaaa ; obtain table of contents from tape /dev/rmt/0m and look for filename containing "eaaa"

# vxrestore -yxf /dev/rmt/0m ; restore the whole content of the tape into current dir, answer 1 and y

# mt -f /dev/rmt/0m rewind ; rewind tape after listing the tape

New future lies ahead..

Hopefully everything will turns out as planned! Insya Allah

Today got me thinking, what do I get if I ever do this so-called drastic move? Is it gonna be beneficial for my future? Or it's just another short burst. Hmm, if you know me well enough, I have this tendency to make sudden, or rather drastic measures towards things that I think would bring some changes (good changes, of course you dum-dum).

I'm not complaining that things I did in the past didn't yield any positive results, it does! Most of 'em actually. At *least* *most* of 'em.

Eh, let's continue tomorrow, kinda sleepy now.

Not as planned, as usual

2010-03-02T14:16:00.004+08:00

Well, like the title said, everything was not as planned, at least for now. But really, things are not really good as of now. Nothing much to do and I engulfed in this kinda "handicapped" situation. Frankly speaking, I learned nothing new in the past few months and this is really sickening.

Einstein once said, "Any man who reads too much and uses his own brain too little falls into lazy habits of thinking". Erk.

Seriously, I don't want myself to fall into "that" category, never. I like to read (not everything, some topics obviously) but I never thought of that until now. I became lazy now, thanks to me who didn't find anything challenging for the past few months.

It's very easy to blame on the situation though, but that's what happened. In reality, *you* shape up to be *who you are* not the situation nor environment nor the people around you.

Now I'm confused. With what should I do next. What should I do? For some obvious reason, only I myself has the knowledge on what should I do with my life. Way to go Captain Obvious.

I need myself some time to think, to really sit down (or stand, walking, whichever deemed suitable) and ponder about everything in life.

"Everything should be as simple as it is, but not simpler. --Einstein"

Hoping for the best...

Pray to God that everything will go as planned...

Amin!

The journey continues... next week!

One command looks like interesting, worth to look up for this:
pax - Extracts, writes, and lists archive files; copies files and directory hierarchies

Nothing here yet!

HP-UX, bdf, du and ...

2007-08-21T11:21:00.002+08:00

If you ever encounter a file system full, say, at this particular partition:
[ROOT gitu2]Z24/X41 # uname -a
HP-UX gitu2 B.11.11 U 9000/800 170187401 unlimited-user license
[ROOT gitu2]Z24/X41 # bdf /usr/sap/Z24/X41
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol30 4620288 4610752 9038 100% /usr/sap/Z24/X41
[ROOT gitu2]Z24/X41#

and you have been trimming, deleting files like crazy, say, you've delete a 1.7G file but when you issue bdf, the utilization still at 100%. But when you checked with du, it shows the current utilization on that particular partition/directory has been reduced. WTF?!

Don't worry dude/dudette. Basically, there are some processes running that currently writing on some files on that directories and until those processes are stopped finishing writting you will not see the free space in bdf.

To identify the processes, run this:
[ROOT gitu2]Z24/X41 # fuser -cu /usr/sap/Z24/X41
/usr/sap/Z24/X41: 7314co(z24adm) 15790co(z24adm) 24426co(z24adm) 10374co(z24adm) 8094mcto(z24adm) 10514co(z24adm) 24418co(z24adm) 24433co(z24adm) 24458co(z24adm) 24432co(z24adm) 24446co(z24adm) 22457co(z24adm) 24385co(z24adm) 12656co(z24adm) 24444co(z24adm) 24439co(z24adm) 24442co(z24adm) 24451co(z24adm) 24438co(z24adm) 24386co(z24adm) 26313co(z24adm) 4756co(z24adm) 24428co(z24adm) 24435co(z24adm) 17512co(z24adm) 24459co(z24adm) 20846co(z24adm) 24431co(z24adm) 24460co(z24adm) 9184co(z24adm) 3585co(z24adm) 24440co(z24adm) 24448co(z24adm) 24417co(z24adm) 24430co(z24adm) 24443co(z24adm) 24338c(z24adm) 24441co(z24adm) 12555co(z24adm) 24461co(z24adm) 24434co(z24adm) 24436co(z24adm) 24445co(z24adm) 24429co(z24adm) 4539c(root) 24437co(z24adm) 11852co(z24adm) 24449co(z24adm) 24450co(z24adm) 26830co(z24adm) 28242c(root)

Ah-ha! It will listed all the eeeviiilll processes. What you need to do is kill all those processes and voila!, you'll get your free space back.

** ACHTUNG **
Don't simply kill the processes until you pretty sure it is safe to kill with the owner of the processes (backup team, or whatever). Use j00r brain d00dz.
