I have given up (for now, at least) the idea of a raid solution but I will still have 2-3 hard disks available for my workstation. If I choose to reinstall from scratch,can I have essentially two different homes?
View 5 RepliesI have a PC with 4 harddisks and one ssd drive, presently PC boots from the 1st harddisk and other harddisks (sometimes 1, 2 or 3, depends upon the requirement) are used for the storage. Now i want to boot the PC from SSD and use the other harddisks for the storage only. My problem is that when system boots it takes 1st harddisk as sda and SSD as sdb, if i am using only one harddisk, and if i use 2 harddisk it takes sdc as SSD. So i am not able to give fix boot point in menu.lst file, if i wish to use root filesystem from SSD.I am using 2.6.33.7 kernel and grub bootloader. I have tried using initrd with udev but not able to include and start udev properly in initrd. I am trying to boot from UUID or LABEL, but no success. Am i missing something in kernel to get the UUID or LABEL.

If I configure an array and then start the Linux installer or boot the rescue CD, I get /dev/sda and /dev/sdb instead of an array. What gives? I need to start installing within the hour so I am desperate for an answer!
View 1 Replies View RelatedI've downloaded 7 ISO images in order to install CentOS as a Virtual Machine on Fusion. First disk goes through successfully, but when I try to "insert" 2nd disk, I get an error message "unable to access the cdrom". I've ejected 1st disk, mounted second. I tried all possible scenarios I could think of, but still getting an error message.
I see the disk mounted in a terminal:
/dev/disk1 600600 600600 0 100% /Volumes/CentOS_5.5_Final
I recently tried installing Lucid x86 on my system beside Windows 7 and managed to screw it up.
My disk setup is this;
Disk A = 3 partitions (1st partition=Windows 2&3 partitions=Data)
Disk B = 1 partition
Disk C = 3 partitions (1st partition=Data 2&3 partitions=Ubuntu & Swap)
Disk A = SATA and internal
Disk B = SATA to USB external
Disk C = SATA to USB external
I want to install Lucid on the 2nd partition on Disk C. And dual boot it with Windows on Disk A.
During Lucid setup i specified the partition for installation (C2) and asked for GRUB to install on Disk A (no partition specified) so GRUB is always used as the dual-boot manager even if the Lucid disk (Disk C) is ejected. Once installed and rebooted i was taken to the GRUB rescue prompt as no installation drive could be found (a long string of numbers (looked like a Disk ID number???) was also shown). Obvviiusly, i could not access either OS on my system at this point. I had my W7 DVD handy so it was just a case of recovering the windows boot manager and i could use my PC but how do i go about installing Lucid with this setup? Should i specify a partition for GRUB to install to? I have a hunch this is where i am going wrong but am too scared to try again and potentially balls things up.
I have never seen this one before (see below) - note how /dev/sda1 is mounted from the first disk listed by fdisk, but /dev/sda2 comes from the second disk; what is going on here? This is what I did: I installed the latest debian "Testing", which went well - it found the disks in the order show by fdisk -l here. When it booted up after installation, it failed because it couldn't find /, which I repaired by editing the grub menu (I told it to start from the other disk), and it came up. But now I had to mount /u01 by hand from /dev/sda1; strange. I suppose I could just go and change the physical disks around, but I'd like to understand this. Any ideas?
# fdisk -l

I have servers which contain SATA disks and SAS disks. I was testing the speed of writing on these servers and I recognized that SAS 10.000 disks much more slowly than the SATA 7200. What do you think about this slowness? What are the reasons of this slowness?
I am giving the below rates (values) which I took from my test (from my comparisons between SAS 10.000 and SATA 7200);
dd if=/dev/zero of=bigfile.txt bs=1024 count=1000000 when this comment was run in SAS disk server, I took this output(10.000 rpm)

I have/had a PC with several hard drives, and a mix of ubuntu and windows on multi boot.The old boot drive died screaming, and I need to start again. (But my data is safe! yay!)
Is there anything special about which drive can be the main drive to start booting from? Or to put it another way, can I install to any of the other 3 and expect it to work, or do I need to switch them around so a different drive is on the connections for the recently dead one?
Got Wintendo7 on one samsung S-ATA disk. ( need it for starcraft2 and Homeworld2... sorry.. )
Now..: Booting Debian Unstable from USB or CD-ROM, then start installer. Tell it to install on second samsung S-ATA disk.
Before I go on, I just feel i will get into some serious trouble with GRUB?
Or will the installer understand, and see the windows7 installation and add it to Grub?
If not, what should I do inside /boot/grub/menu.lst when Debian is up and running?
During installation when i set the partitions i have to provide a Name and a Label. What is the difference of these? It looks like only one should be needed. Any problems of using the same name for both?

This question has been bugging me for a few days now: How do you mount, say, 3 HDDs to a single partition. From what I've heard, it's possible, but I'd like to know how. I'm running Crunchbang! Linux, based on Ubuntu, in case you're wondering.

View 9 Replies View RelatedFirst and foremost, I really appreciate this newer release of Ubuntu 10.10. My boss wanted to use SLAX, but I had great experience with 8.10 and I have installed 10.10 on laptops and netbooks. on with the challenge for the day: I have configured a user's profile on 10.10 to startup Firefox in kiosk to go to our secure portal. The problem is I don't particularly care to REDO configure a user's profile session over and over.
So, if any of you whiz kids out there can come up with a better way to copy a user's profile...particularly the files that are used for Mozilla Firefox so that I can just copy and paste the files onto another hard drive with a fresh 10.10 that would be great.
The ONLY issue I have working with Linux is that I can not rapidly deploy my settings I have set for 'user' as I can with Windows. I am sure if there was a way to do this, deployment of Ubuntu 10.10 would go MUCH faster. As it stands, if I am able to pull this off...there will be a potential of removing Windows desktops. Which is fine for me because I can manage desktops a little easier on this platform than Windows.
This is what I have installed in Ubuntu:
IcedTea (for Java plugin for Firefox)
Profile Editor
R-Kiosk
All those work great with Firefox, but getting those installed on a new system is a bit daunting.especially when some users suggest doing cloning when in reality...I plan to do the install via LiveCD and THEN hopefully create the user on the fly in Terminal and copy the user files needed off a flash drive into the home/user folder
I have a Mac Pro 1.1 and am having trouble installing Debian. I installed rEFIt but it won't show my install and live disks at startup.

View 4 Replies View RelatedOne of my disks in my computer crashed, it was the one containing /boot and some data partitions. The other system and /home partitions were on a second disk, which is ok.
I was wondering, can I create a new /boot partition, and keep on using the rest of the system? Can I somehow do it with a chroot from a live/installer disk, run grub, and use my system again? I have another disk which I can put in the system, but there is even an unused partition on the disk which is ok (but it is rather big for /boot).
The last days I try to find a good and easy solution to keep new installed Servers with same basic configuration. For example every new Installed Server should have:
- phpmyadmin installed and configured
- munin installed and configured
- mysql server with some predefined users and passwords
- same users created with existing ssh keys. also ~/.ssh/authorized_keys file with pub key inside
At the moment I use some bash script to create the users and sync the keys. Basically I need to install predefined packages and remove some other packages configure some config files (or copy working configs). I have looked at cfengine and puppet Server. And I am asking my self if this tools are overkill for this task.
By fiat I must distribute my homedirs across multiple physical disks/partitions. Unfortunately this is not open to discussion so obvious solutions like a lvm home partition are not available to me. The issue: Users created with homedirs on the main home partition (the one created as home during the f13 install) behave as expected, but if I create them on a different partition (home9 for the sake of this example) the users are not able to login (dropped back to login screen), nor run x-apps if su -'d to in a konsole.
If I 'su - <user-on-home9>' in a konsole, I get delivered to the /home9/<user-on-home9> as expected, but x-apps fail with the error: 'cannot open display: :0'. This can be temporarily fixed with the command 'xhost +SI:localhost:<user-on-home9>', but I would rather fix it permanently at the source.
This appears to be an selinux problem from the following.The contexts of the the two rootdirs are the same
% ls -Zd /home /home9
drwxr-xr-x. root root system_u:object_r:home_root_t:s0 /home
drwxr-xr-x. root root system_u:object_r:home_root_t:s0 /home9
but when I create the users (using useradd or the gui) their respective contexts differ:
% ls -Zd /home/user5 /home9/user6
[Code]...
So, my questions for you selinux experts are 1) is it possible to have homedirs spread across multiple partitions with selinux, and if so, how, 2) Why, even when I manually set the dir/file contexts to match a properly functioning user5 from /home, do users from /home9 still not work (as far as login and x-apps).
I want to build a custom system and I need your opinions. I have an old laptop which I want to configure as a system for troubleshooting purpose, my idea is to have multi-boot system with multiple root file systems, e.g. one root file system has only BIND to work as DNS server, another root file system has only Samba, etc., and I can choose which system to boot into from grub, or a custom menu after booting grub.
I thought of setting multiple partitions and install a full system on each one, but I thought that there might be a better way to do this, I'd like to hear your opinions.
My system already has Winxp, Vista and Ubuntu. I'd like to try F11 on my system with about 50 GB free space. How do I set up the installer so that it will install F11, configure the boot loader to recognize all (multiple Oss) so I can load any one of them? I know Fedora has no problem to boot winxp and Vista, but how to set things up so it can also boot other Linux OS on the same system?

Initially after booting with the media it doesnt even prompt me to press any key to boot from CD or Dvd or I get any screen to select the option for the mode of installation like text based installation or graphical installation..it hardly shows me this screen for even a fraction of second as well...
It takes me to the screen
1) Install or upgrade fedora
2) rescue existing installation...
3)
4) Memory test
when I click on install fedora I am taken to the fedora splash screen and nothing goes ahead... I tried in rescue mode as well... In rescue mode it asks me for language selection...keyboard layout... later it doesnt go ahead as well... I have checked the installation media and it confirmed that the installation media is good...
