Quanmax QutePC 1000 Intel Atom Nettop

This is a Quanmax CutePC 1000, an intel atom based nettop.

The unit is soo silent, small power adaptor, and cost only 250 USD here.

What next ?

• Regular desktop.
  I tested with Win 7, Fedora 11, Centos 4. Fedora 12 failed to be installed from USB DVD.
• Thin Client for VDI / RDP Station
• “Fat” Client for VDI

Cons:

• The manufacturer stated we can put CF Card, but there is no CF Card Slot inside. i guess we can use CF if only we use SATA to CF adapter.
• Lack of PXE boot

RDP is for every people

RJ45 Network Patch Panel 1U for visio

By default, there is only 2U patch panel in visio stencil. Here is a simple and quite stupid way to create 1U patch panel:

1. Make sure “Rack-mounted Equipment” Shapes are open
2. Create 1U “shelf”
3. Add my patch-panel-1u stencil on top of the newly created 1U shelf

6 TB on a single blade !

6 TB drives will be put on top of the blade enclosure, originally uploaded by chenull.

Blades are glory, if concerning about power. But it has limitation, space. Usually blades come with 2.5 inch drive trays. When you need more, and you are not a blonde, go extend the sata cable. surely, it’s not pretty looking though

Bridging on OpenVZ

I need to create a bridge from an interface inside container, which bridge to my physical LAN. I followed the tutorial / guides on http://wiki.openvz.org/Virtual_Ethernet_device, but it doesn’t seem to make bridging works correctly. So I made some changes:

1. Install bridge-utils

   yum install bridge-utils

when she refused to be logical

These last 3 weeks, is a frustating moment. Actually my job is simple: install servers, then implement a disaster recovery plan. The first problem arose when i stupidly didn’t know how to manage a simple kernel module load at early boot stage via initrd. This took me 10 days to discover.

The worse is the last 12 days, when simply i need that kernel module to be loaded at boot time on a “centos livecd”. i need the livecd version of centos for recovering my server in case of severe hardware failures. all the toolsets, including coffees, bags of tong tji tea, new macbook battery (wow, how many rupiahs i’ve spent? –my last battery was unfortunately died), new 2GB RAM for the macbook, “tahu baxo” ungaran, “martabak mesir”, cadburry choco drinks, are set, but that-actually-easy-task is frustating me and took me 12 days to discover the solution. evenmore, the solution i’ve found is somewhat really simple and nothing “geeky” at all.

i think now she refused to be logical. i think she is more “human” now, forgot of what her dignity is. Fuhh.. or maybe i am getting old, old enough.

Enough for this nonsense. Here what should i do next time:

1. mostly, kernel module / driver need to be “the same version” with the kernel loaded at boot time
2. create livecd / recovery cd with i386 arch, and on a host WITHOUT LVM (because of a bug on mkinitrd)
3. simply do trial and error as much as i can

sinyal

karena sering nya orang komplain ke saya, bahwa telpun tidak diangkat2 siang ini, ini saya upload screen shot HP saya. Hari ini ada 2 kali katanya telpun tidak diangkat, lha karena emang tidak ada telpun masuk siang ini.

yang selama ini saya rasakan emang sinyal disini (rumah) ndak gitu bagus, telpun sering putus ditengah2, suara lawan bicara seperti ngomong didalam air, dan kalau browsing via HP lambat (entah full bw ne entah sinyal nya).

Ini di salah satu VPS Xen:

PERHATIAN: Don’t try this at home !!!

openvz kernel & megasr scsi on centos / rhel 5

Sudah 5 hari ini saya tidak mengerjakan pekerjaan lain kecuali 1 hal: belajar memahami linux kernel. Ini pun masih kapasitas sebagai user, bukan developer (hiks… betapa malunya).

Problem:
My hardware has a LSI MegaRAID 8208ELP (megasr) SCSI SAS controller. It shipped with RHEL 5 driver. I need to setup openVZ, unfortunately, rhel5 based openvz kernel is refusing megasr.ko to be loaded at boot time. Error message at boot was:

Loading megasr.ko module
megasr: disagrees about version of symbol struct_module
insmod: error inserting '/lib/megasr.ko': -1 Invalid module format

From what i’ve googled, they (megasr.ko and ovzkernel) have different kernel ‘version’ so they refused to work together.

Solution:

1. Download and install ovzkernel & ovzkernel-devel (use PAE if neccessary)
2. Go to lsi.com, and DON’T download the current version of the driver. Download the previous version. This is the URL: Redhat 5.x or mirrored here
3. Extract the zip file,then cd to shim/library/rhel5-32
4. do

   make -C /usr/src/kernels/2.6.18-53.el5.028stab051.1-PAE-i686 M=$PWD
   

5. copy the megasr.ko in /lib/modules/2.6.18-53.el5.028stab051.1-PAE-i686/updates

6. depmod 2.6.18-53.el5.028stab051.1-PAE-i686

7. /sbin/mkinitrd /boot/initrd-2.6.18-53.el5.028stab051.1PAE.img 2.6.18-53.el5.028stab051.1PAE

8. reboot!

NOTE: don’t copy paste, since the kernel version will always been updated

hope this help someone else, at least me

thanks for RUBEN for the correction
