Hardware :: Building A Backblaze Storage Pod?
Mar 10, 2010
I'm building one of the backblaze storage pods:
blog.backblaze.com/2009/09/01/petabytes-on-a-budget-how-to-build-cheap-cloud-storage/
I have followed the specs they give exactly and i have almost completed it but I am stuck trying to mount the raids. There are 3 RAID6 and i recieve the same error for each one
Code:
mount /dev/md0 /mnt/raid0
mount: wrong fs type, bad option, bad superblock on /dev/md0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
This is what i have done(ill just show one since they are identical except for which drives make the raid of course)
Code:
mdadm --detail /dev/md0
/dev/md0:
Version : 00.90
Creation Time : Thu Mar 4 14:50:11 2010

I am trying to figure out the best server configuration for the following:Low power (I want to plug the server in and forget about it)High redundancy of data (I don't want to loose my music and documents!)The ability to stream music + movies to laptop (maybe subsonic or Jinzora)VPN server with IPsec or OpenVPN NAS $800 budget 2TB with ability to add more drives :Unix Server with software RAID (maybe RAID6)
VPN setup on virtual OS via VirtualBox
NAS setup on virtual OS via VirtualBox
My Questions:What would be the best raid configuration if I wanted at least 2TB of data and the ability to add more disks when the space begins to add up?What would be the best OS to use for setting up a software RAID (is a FakeRAID a better solution)?Does it make more sense to separate the VPN and NAS with different OS's?My goal will be to access my data from any computer from anywhere but mostly just my Laptop from work.

I need some advice or tips or maybe your own experiences about building a home data storage or NAS.Here's some thoughts / requirements I think it should have:It should expandable. I'll stick a couple of 1TB HDDs and a little later I'll stick some moreIt should easily integrated to both Ubuntu and Windows 7. Ideally it'll be an integrated part of the filesystem.I'm thinking some sort of RAID as a backing up my data. RAID 1 seems like a such a waste but then again, these days, HDDs are cheap.And when I do add more HDDs, I'd like them to appear as one big storage unit instead of separate drives.Any suggestions and tips on how to go about this is welcome. Questions are plenty: should I go with server hardware or is bigger ATX case and standard hardware enough? I'll need some pointers so keep 'em coming

I'm interested in buying a new hardware for my company. The old server (now 10 years old) should be replaced with a new one. Till now, I was looking on different hardware suppliers, boards and different other places. I found a Tyan board [URL]. The hardware spec is quite interesting and the board would fullfill our claims.
how both storage devices will be supported by Ubuntu or Debian??
- SATA-Controller: AMD SP5100
- SAS-Controller: LSI 1068E

I am trying to do the cluster storage with the Rock Cluster storage operating system . I have install the rock cluster on the main server . and I want to connect the client with the PXE boot . when I starting the client then it boot from the PXE boot into the mode of compute node. but it ask the where is to be stored the I have give the path..then server says that not able to find the directory path.
Steps:-
1) insert-ethers
2) client is started with the PXE boot.
3) it detects the dhcp .
4) At last it demand where is to be started by cd-rom, harddisk ,nfs etc.
then I started with the nfs and I have given the lanIp of server.and server is detecting the client but client is not finding the filesystem directory. into export partition directory but it is not taking path.
PATH:-
/export/rock/install it is not finding this path then it is not able to start the o/s from PXE boot..Is there any solution and manual of rock or anyother solution then u can reply to me...

I am having trouble building vim with gui from source on Fedora 13. I am using
Code:
./configure --enable-gui=auto --with-features=huge --prefix=$HOME/myvim
but I get
Quote:
checking for X... (cached) no
checking if X11 header files can be found... no
checking --enable-gui argument... no GUI support.
I have installed GTK and X11 dev packages. What's missing?
[URL]
I'm building from source because the packaged Vim doesn't have all the features I want.

I have been meaning to do this for awhile. I have a relatively decent machine currently running FreeNAS, a BSD based NAS system. It works great as a NAS box, but now I want it to do more. I want it to act as a file server/NAS, also as a router for my home network, so obviously I will add a second ethernet port as well as wireless "N" capability. As a router, I want to have fine control over my home computers. And, I have a multiple camera security setup, using Motion, that I want to run on this machine 24/7. I know Motion doesn't take a huge amount of horsepower, since I am currently running it on an inexpensive laptop running Squeeze.
What I would like advice on is how some other people on this forum would accomplish this. FreeNAS works great for what it was designed for, as well as IPCop, but neither will do all that I want, so I plan to run Debian on it, most likely Squeeze, as it will soon be Stable.

I am returning to Ubuntu as my primary OS. For this, I am building a new system (I have a beast of a Windows desktop, but retiring that as an HTPC and building a new desktop). Will be moving some items from the Windows desktop like the speakers, keyboard/mouse, monitors, etc, that will not serve with the HTPC configuration. Basically, this is what I am building (amost identical to my current Windows machine, except it's a Core2Quad and has 12GB of RAM):
i7-860
P55 chipset motherboard
8GB of RAM
system/boot volume volume 2x64GB 2nd gen 64GB SSDs in RAID0 (have hardware garbage collection so will run find in RAID)
[code]....
Video Card: with 10.04, should I go with ATI or nVidia for a card? Am running triple monitors, and will be gaming using Cross-Games and Cedega. Which drivers between the two manufacturers is performing the best and would be best for gaming/multiple monitors.
RAID Card: The 2320 says it has native support in the 2.6.25 kernel. I get good speeds (500-600 MB/sec on both the SSDs and the RAID5) and no troubles with it on the Win Desktop. Should I have any issues with it under 10.04 or would there be a suggestion in the <$350 price range to replace it with? Or, would running the ICH10R off the motherboard work with the alternate CD?
SSD Setup: What partitions would be best to keep off the SSD volume and on the RAID5? I know /tmp, /home, /var, and /swap should be kept off the SSDs to reduce the excessive writes. Any other suggestions? With a 128GB system/boot volume, what would you do for partition sizes there?
Sound Card: Is the Omega supported under 10.04? Or another suggestion for good 7.1 surround sound?

I run a small business and are right now in the need of a telephone solution to run on my Ubuntu server. Obviously there's some alternatives out there that seems really extensive, maybe too extensive, so if there's anyone here that would like to share their experiences and thoughts in this area

I am going to buy new computer, will assemble it myself. I have searched extensively this forum and finally at least decided on PSU, Corsair VX450 which is available in India also. I want to do these 3 things on my new computer:
Browse internet.
Do Programming (C, Lisp, Emacs) on Arch/Debian Linux.
Play 1080p/720p HD/Blu-Ray videos with 6000kbps bitrate.
No games and no Windows
I already have Samsung SyncMaster 2243LNX monitor and a SONY DVD-ROM. Now I need to decide on other components like CPU, MOBO, Case, HDD. Searching forums make me convince on WD HDD and Gigabyte MOBO. Regarding CPU I am still confused on AMD vs Intel. I have understood that I don't need 4-Cores, 2 core will suffice my needs.

Do I undersatnd correct? If you build LAN with several Linux PCs and no DHCP server, you will need to configure every computer yourself. But if you add one more PC to this LAN which is DHCP server, all you need is to configure this DHCP server and write in config files of other computers to use DHCP, network will work without configuring other computers?

Anywho i am trying to get wine to work but after strugglign with many dependency issues i tried to build it manually but it keeps telling me to install the 32 bit development libraries. how to do this (i am currently using fedora 14 having identical issues) and i cant get either crossover games to work with 3d games nor can i get wine to play any 3D related games (does regular windows programs just fine)

I'm trying to build boost on a 64-bit CentOS 5.4 install. I have Python 2.6.4 built and installed at /opt/Python_2.6.4/, and I've appended the user-config.jam file with:
using python : 2.6 : /opt/Python_2.6.4/python : /opt/Python_2.6.4/Include : /opt/Python_2.6.4/Lib ;
The standard system Python is 2.4.1 but the tools I'm using require 2.6, so I've built this version and installed it independently of the system version 2.4.1 to avoid any conflicts.
As I'm sure you've already imagined, I get the error:
LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)
I see that this is a long standing bug, but I have yet to find a fix. I've tried various CCFLAGS, CXXFLAGS, etc. to push for a 64-bit compile or a 32-bit compile (-m64 or -m32).
The offending file is pyport.h - is there a 64-bit friendly version that I don't know about?

Can I use my USB to act as a RAM storage? [URL]... I doubt if there will be significant increase in performance..Otherwise RAM manufacturers will be out of business! morever I think Linux already uses this through SWAP. I have very poor RAM (512 MB) , Some KDE distros specify >=1 GB....How can I run these smoothly? I have ample HDD space. By increasing SWAP , can I enhance performance? Te best would be to buy a RAM chip but mine is rather old 512 MB (DDR1). It is not available and even if it is there seems to be costlier than DDR2 and DDR3.

I have just added 2 146gb disks to an existing RAID5 system running Oracle Enterprise Linux 5.4. I used Dells open manage software to rebuild the RAID which was successful although I cannot see the additional storage when I look on the system. Basically how do I get Linux to show the new storage and then add it to an existing partition.

I am trying to build a system that will run both KDE and GNOME. I currently have just GNOME installed. So I need to install KDE and KDM (which I know how to do). The thing that I don't know how to do is make it default to KDM when it boots rather than GDM. Also I need a way to get rid of the GNOME apps in the menus in KDE and the KDE apps in the menus in GNOME. Also, this system in running Fedora 11 x86_64

I am trying to compile a kernel (so that the USBIP module gets built, I've enabled it via menuconfig) in the following directory:
Is this src tree "intended" to be rebuilt?
I'm trying to compile an "EXPERIMENTAL" module (w/in the tree already) USBIP so this seems to be my ONLY recourse. I do not have the ability to connect the machine to the net, nor bring in things like non-professionally burned CD's nor flash drives...

I want to be able to create a Dialog (similar to the one for Winetricks, run it without parameters to see it) with a checklist that tells my script to go out and download whatever scripts of mine I've selected. I also wish to make a GUI for some of my more complex scripts, such as my Backup script so I can have a nice looking menu instead of a text based one.Does anybody know a good place to learn how to do this, with lots of explanations and breakdowns of each part of the script?

I'm starting the process of purchasing parts for a desktop. My target price range is $300-$400. I want to be able to comfortably run a modern linux-based operating system, but do not necessarily need an advanced system. It will be used for internet (including videos on hulu.com), office related tasks, and some light editing of standard definition mpeg4 video. I'd like some room to potentially do upgrades and updates in the future. I'm looking for any kind of suggestions or advice that might be helpful, because I've never done anything like this before.
Here are the parts and approximate prices that I've found so far, shopping primarily on pricegrabber.com. Again, feel free to comment on anything. Intel DG41TY motherboard - $70 (X4500 G

I was using amarok fine with 10.04, upgraded to 10.10 alpha, still worked fine. Decided alpha had a few bugs I didn't like so I completely removed it, installed 10.04 from scratch again (I have two partitions, / and /home, only formatted /). Now I can't get amarok to build for me at all. It plays mp3's no problem but when I try to build my collection it pretends to (takes a few minutes but goes relatively fast compared to what it should take to build) then shows 0 songs. I've already tried deleting amarok inside of /home/user/.kde/share/apps/amarok

I have been trying to build the HP Qlogic Netxen, nx_nic, driver on Ferdora13 kernel 2.6.33 but facing with "missing kernel-devel package" errors. As per the instructions in the driver spec, when i try to do rpm build, i get this error. I tried the rpm build installing kernel-devel-i686 pkg but it only shoots back with
error: Failed build dependencies:
kernel-devel-i586 = package is needed by hp-nx_nic-4.0.544-2.src
But when I installed kernel-devel-i586 pkg for kernel 2.6.30 the rpm build continued beyond this error point only to give some other RPM build error atleast to say there was no missing kernel-devel pkg error. Has anybody come across any such error with any other driver? or nx_nic in specific? Does this error mean kernel-devel-i586 a MUST for this driver? As far as I know there is no -i586 pkg for kernel 2.6.33 when i searched in kernel-devel repository! I am not sure, if this forum is right place for posting this question. If not, pls re-direct me to the right one.
