General :: Find No Way Of Choosing Whether Linear Or Striped?
Feb 19, 2010
I have two drives (sde 120Gb) and sdh(250Gb) which I want to use for the following setup: sde + 120Gb of sdh as a striped LVM as an ext4 partition remaining 130Gb of sdh as a separate ext4 partition I am able to use the build in partition manager in Mandriva to set up the rest of my disks and I can set up an LVM as planned above, but I find no way of choosing whether it should be linear or striped. This means I will most likely have to do it from the command line. Can someone tell correct commands to set it up?
I am dealing with a problem which I cannot seem to fix myself.I have a computer (age ~1 year) on which I am trying to install Ubuntu.The problem which I am facing is at the point of choosing to boot from the CD it says 'cannot find bootable device'.Note that this PC does not have a floppy drive and that I do not have a 1GB USB stick. I do have a 256MB USB stick.
I have 3 separate hard drives. Drives 1 and 2 are striped together and I have openSUSE 11.3 installed. On the third disk I have WindowsXP-64 Professional. I installed SUSE first with the third disk unplugged. I then installed WinXP with the two SUSE disks unplugged. My fdisk -l is:
I've installed Ubuntu on my PS3 system, and when I play a DVD video using VLC the video is striped with green vertical bars. Naturally, i can't watch it like this, so I also tried Movie Player, which frezzes up alot, so then I tried Kaffine, which failed to work at all! Every video player I know is useless when it comes to playing some DVDs on my PS3, (I say some because others work fine, and no, there's nothing wrong with the DVDs thereselves).
I have installed Opensuse 11.4 and the desktop won't start i get an green striped screen, i have tried to run yast but it seems mine NVIDIA isn't correct installed.
I have an NVidia SE6150 Graphic Card and i have tried to configure the startup parameter vga=0x317, i have changed this to vga=0 to get vesa mode but that doesn't work, i have an wide screen monitor that supports 24 bit and 1360x768.
I'm trying to find out which one is safer when it comes down to recovery process in case of a drive failure
A RAID5 created in mdadm or a Stripe RAID created on pure LVM
the RAID is purely for data storage for a SAMBA server, the OS will reside on its own drive.Ideally the RAID physical hard drives should be re-build on another machine in case of catastrophic server failure (mother board problem, or any other random problems as an example)I can't decide which of the 2 software RAID method is more convenient and safest, don't care about performance, it'll be a dedicated server for mass storage, it's going to mirror other 3 file servers on fakeRAIDs (dmraid), it's simply a redundant backup for the backups
The important goal here is portability.from what've read it appears that LVM might be more portable?but according to some dated (2009) info the mdadm seems to be a bit buggy when it comes to rebuilding the array, yet LVM doesn't appear that safe either which one would you pick for ease to rebuild on catastrophic failures?
Another step before turning to Linux. My DVD/CD burner is not supported by Linux. Can someone suggest a cheap burner that works well in Linux. My travails thru Newegg and other locales has borne no fruit.
Used ubuntu a little, few days ago tried booting with puppy linux on usb drive.
I was amazed by its speed, since everything runs in ram, its not comparable with w7. That is the key feature im looking for.
I know, that the most common recommendation here, is to "try out different *nix based OS-es and find the one that suits".
I hope i can rely on other people experience, who have comparable system and silmilar hopes.
What i expect?
-working infrared -speedstep -hibernation?! -support for canon camera -ACPI (crucial, since t41 has "fan always on" issue) -quick boot -constant saving (puppy saves data to memory, which is a problem is power-cut happens)
Im sure puppy can fill out most of these requirements, but still im looking word from you guys.
Ive heard a lot good about algo zenwalk, vector, MijnPup, igelle...
Oh, maybe even tinycore will work...
There are simply so many of them, but i would like to sort out one which has periodical updates and has fulfilled my requirements. Also, Gnome interface would be nice.
I state that, i wont be needing bundled software, because i can get what i want later on and i don't want excess trouble uninstalling software.
I've been using linux for a while (various distros) but somehow they dissapointed me. I know what I'm looking for, a lightweight, fast, minimalist but customizable enough, with no specific graphical environment, bleeding edge distro for a new laptop (used for studying and surfing internet), that hopefully works with my hardware.
I want to have the possibility to compile from source to make my own changes but also to install from binaries easily. I'm not a linux expert, not even an advanced user but I'm willing to learn anything to get my distro running so I'm not looking for a full out of the box distro. It would be great if this distro also had a good community.
Like most long-time Windows users, I am a bit (very!) confused by the manual partitioning of Linux, and particularly the semi-guided partitioning of Ubuntu 10. I first tried Ubuntu way back in version 5, and it was easy to install, I could identify the correct partition by SIZE, not the enigmatic sdb1(0,1,0) nomenclature used in 10.
I set up a 32GB partition, figuring I could install Ubuntu to that, letting it manage the entire space. Instead, I can't even figure out which drive or partition is which (three hard drives, 8 partitions).
Why can't Linux (most distros--some are clear) at least give you a "sdb (0,1,0) 25.6GB" "hint" that you are installing to where you want to?
I've tried thirty versions/distros of Linux over the years (starting with Corel Linux) and for the same handful of reasons, never replaced Windows, or for that matter, even used Linux much.
1) Partitioning woes (explained above)
2) Inability to play well with Windows networks
3) ALSA? I've NEVER gotten it to work for me; it either works out of the box or I never have sound
4) Needing to download every audio and video codec and it's associated libraries to play an mp3 and watch a Divx movie
5) Completely non-intuitive naming of almost every part of Linux (why can't the names at least hint at what they are?)
Yes, I want a more Windows-like Linux. I grew up with the DOS command prompt. Been there, done that.
The card in question is a PC Card (PCMCIA) 16Bit Intel Series 2 Flash Memory Card (2MB) and I want to be able to read from and write to the card. I've rebuilt latest stable kernel (2.6.37.2) with all the PCMCIA options turned on or built as modules. I've got an SRAM card, a CompactFlash Card (in a CF to PC-Card adapter) and the Linear Flash card to try, the SRAM card I'm not expecting greatness from, but hoping to prove that the slot works (it registers, but doesn't get much reported from lspcmcia). The CF card in the adapter works. I'm expecting to see a block device in /dev but nothing appears lspci:
i am writing a netfilter module for linux 2.6.34.6-47 / 2.6.35. while i could capture the packets on the incoming hook since the same came as a single packet in probably the allocated skbuff area by the stack, i found that packets going out of the machine are getting splitted into linear and non-linear area. skb->data gives the total length of packet as correct, but when i extract skb-> data to print it, it prints only ip and tcp header. Now to treat the data i need to extract it and then push it back on the route.
To clarify if my data is 3 bytes . the total length by passing pointers show as 55 bytes = ( 52 byte of header + 3 byte of data), but i can't access these 3 bytes by using skb->tail - skb->data. how to extract outgoing data for any further action and then put it back on route for further encapsulation by the L2 stack or whatever. will skb_linearize() or skb_linearize_cow() be of any use , if yes how and why?
I am using mdadm 2.6.4 for managing RAIDs on Linux kernel 2.6.18. I've a query like whenever I tried to add a new disk to a running linear array(JBOD)i get a message "cannot add new disk to this array".
The exact steps are as follows: create a new array as: mdadm -C /dev/md0 -llinear -n2 /dev/sata/ /dev/sata2 It is getting added and i am able to see with -D command.
Now add a new disk sata3 as follows: mdadm --grow /dev/md0 --add /dev/sata3 I get the output as: md: sdb has invalid sb, not importing! md: md_import_device returned -22 mdadm: cannot add new disk to this array.
So my first doubt is whether mdadm 2.6.4 supports this features or not if it supports then do I need to change the driver?
Ext2, ext3, or ext4? I first used ext4 with Slackware, but when I tried my Puppy live CD the only partition I could mount was the Windows one. I started over and used ext2 and Puppy will mount it. I'm willing to start over and use ext 3 if it will also work with Puppy and there is an advantage to using ext3 over ext2. Puppy saw the ext4 partitions, but wouldn't mount them.
I was in the process of installing Ubuntu 11.10, but got stuck choosing which file system to use. ext3 and ext4; which is better for a personal desktop? If ext4 is better, will it work well on my old PC (bought 3 years ago), or perhaps ext4 is not actually compatible with an old hard disk?
I want to plot a set of data in only one plot.The problem is that some points of the data should be better plotted in a linear scale (lets say 0 to 100,000) but there are other data points that, exceding the value 100,000, would be better plotted in a logarithmic scale, as they goes in the range 100,000 to 500,000,000. Let's say the data is:
Code:
X Y 0 100 10000 80 20000 75
[code]....
Is there a way to plot all these points in the same plot in only one X-axis showing two different ranges in that axis: linear: 0-100,000 logarithmic: 100,000 - 1,000,000,000?The axis would be read, for example, as:
I tried to add a new launcher to a xfce panel on an Ubuntu 9.04. The problem is that I want to create a launcher for a .txt file - and the launcher does not give me the option of choosing "type". I read the following:
if I were to install an RPM package, say MySQL, in Fedora 12 x86_64, which one should I download? MySQL provides builds for RHEL5, etc. So is there a 1-to-1 correspondence between RHEL and Fedora?
I have been a Ubuntu user for quite some time, but now I'm thinking about installing a Red Hat based distro on my laptop, so that I can learn another area of Linux. Can someone suggest good distro?I'm looking for something that is stable, good repositories, up to date with latest technologies/techniques etc.
I'm planning to build a NAS using spare bits of PC. I'm hoping to run the OS from a CF card. I want the machine to host music and also general files. I'm planning to install TwonkyMedia Server for the music.
1. I'd like to choose a small distribution, but one that is easy for me to deploy and manage (I'm new to Linux, but I am an IT professional). What shall I use?
2. I'd like to understand the implications of using Compact Flash. Will the OS need to write to disk? Can I configure my installation so that the CF card is read-only and provide a small writeable partition on my hard drive for any required IO? Should I not bother, and put it all on HD? (My motivation for using CF was to limit power-consumption/noise/heat).
I'm writing a script in Python and wanted to make an gui for it. Now I wanted something like zenity or easygui, but with more options of how you can make you gui look. The script I'm making is for tethered shooting with an camera. what i'll do is read/change values, capture images So what would be the best option?
I have noticed that the icon for launcherspplication in terminal) I create has changed.The icon was previously "preferred.png" but now it is "nonpreferred.png" - see attached pics. ow can I select the "preferred.png" icon when I create a launcher? Also, in what directory are these located?
In the past (before UpStart was used in Ubuntu) I was able to configure multiple boot items in Grub menu to load the same kernel but into different runlevels. I had configured runlevel 3 (I went into /etc/rc3.d/ and removed the symlink to /etc/init.d/gdm) to be w/o GDM, so that if I had chosen it, my box would not boot into X. How can I achieve the same effect in Lucid?
I've used Ubuntu just a couple of times, and I've Never performed the Installation. I've been a Windows user mostly.But I'm ready for a change. I would like to Install Linux on my Desktop & Netbook Computer.Problem is, how to go about it.On the Desktop, I'm not the only person using it, and while I'm all & ready to try Ubuntu (Specially since XP Broke 3 days ago and the Format is impending) The rest of the people using the PC aren't. On the Netbook, right now I can't since I'm working on something, and I'm worried about compatibility issues between Platforms.So I did some research on how to get both Platforms up and running, and I found Wubi. Seemed like a perfect way to start!However, I downloaded the client, and when Downloading the rest of the Installation software, It just took way too long!On ETA it marked 4 hours at first (sure enough, it took little more than that) but then it gave me a new ETA of 8 HOURS!
Is there any other way to download it? Other than the 1.6 Mb Client file? & For the Desktop. Since I'm formating the HD anyway, What steps should I follow to install both OS on it?
what DVB-T USB tuner should I buy? I expect it to have full support including the remote control operation. Intended use is for Ubuntu with XBMC installed.
