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 11 RepliesI am tasked with setting up 3 out of the 6 servers and dividing up 500GB of space in the most efficient manner amongst the 3 servers. The space is in a pool which can be assigned to virtual drives. Each virtual drive can be assigned as disk0 or disk1 and so on to one or more servers. They'll be running CentOS.
On the second try I came up with this scheme:
shared sda1 -- /boot (ext3)
shared sda2 -- /home (ext3)

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 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 am looking for an application (better kde one) that can search two external hard disks I have and find any duplicate files. I did some backups before to one disk which i copied few years ago to the other disk. Right now I would like some program to check files and tell me if there are the same.
View 9 Replies View RelatedI 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.
First 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
Alright, I have this issue on both SystemRescueCD and Debian Squeeze. I have an ASUS P5Q Turbo board that supports hardware RAID. 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 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.

I`d like to know what happens when with the disks the we include in the installation process of Fedora 15.Obviously, the HD we choose to be the system is entirely formated and reconfigured. But what about the others?hat does happen to them? I`m asking this because I have included two brand new disks of 2 TB, one of them with 900.000 files and the other empty, both of them formated with ext4, and completely functional on Fedora 14.However, after the upgrade, in the very first Fedora 15 boot, these disks disapeared from "places", and could not be mounted even via terminal. Opening the Gnome Disk Utility, I found out they had been changed to VLM (instead of ext4) and that they also lost their original lable. I am starting to be concerned because all the data there was important to me.

I'm having a problem with my usb disks, on opensuse 11.2. USB disks only mount the first time after booting.
The scenario is, I boot, then I plug a usb disk. It mounts properly and I can use it. After I unmount it and unplug the disk, I try to plug it in and it doesn't mount. And none of my other usb disks will mount as well.
The only workaround is to reboot.
I checked /var/log/messages, and the disk is being detected, it's just not being mounted.
I have a computer with XP & Ubuntu dual-boot. My arrangement is like this:Physical hard drive #1, (NTFS XP partition, ext3 Ubuntu partition)Physical hard drive #2, (NTFS documents partition)The Ubuntu partition is always mounted, but the other 2 have to be mounted every-time I boot up.

View 4 Replies View RelatedI am triple booting Ubuntu 11.04, Win 7 and Win XP. Linux is on a separate EXT HDD, both Windows 7 and XP are on another NTFS HDD and all the work files etc. on a third NTFS HDD, all are SCSI disks.
When I start Ubuntu how do I make it automatically mount the NTFS disks? At the moment I only see the files on the Linux disc.
When using usb disks, there seems to be a difference in how they are mounted, based on the filesystem type on the disk.Vfat disks are mounted read/write for users, while extN filesystems are not.While I can fix that for individual devices, I would like to find a general solution, so that any usb storage device with any filesystem is mounted read/write for users.
View 1 Replies View RelatedI know how to modify the /etc file to change permissions, but I don't think that it could apply to this:
I'm using my Ubuntu desktop to compile Linux From Scratch onto a Virtual Box disk image. I can make it mountable by using a vdfuse program I downloaded, but then I have to use sudo to mount the actual partition. I do not want to give another account the ability to use sudo.
p.s. does this only happen to certain distros, or is a part of the Linux kernel?
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).
how do i mount extra harddrives...?
- After a hardrive crash which took out my opensuse 11.2, I installed three new harddrives instead of the old ones. I have installed xp. To see of I could triple boot, i thereafter put in linux mint. I did not like that and installed opensuse 11.3 - to ensure it would place itself on the two second harddrives (formatted in ntfs and with some data on) i before installation took those cables off.. And now alas.. there are no mount points.
So I tried yast, and found the partitioner, chose edit tried to put mount points .. however.. nothing seemed to have happened...
Finally got FC8 installed on new machine, and now it won't mount CDs/DVDs - didn't change anything in BIOS, CD/DVD drive is only thing on the IDE controller (HD is SATA) so is it likely a driver issue? FC8 seemed to have correct (or at least working) drivers for LAN, audio, SATA, etc.
View 1 Replies View Relatedmy grandfather uses a linux machine for web browsing, emails etc. So he mostly uses Firefox, Thunderbird and sometimes also Skype and now he has also Jabber account. Currently there is Pclinuxos 2009 installed (the newest one with KDE 3.5). I used a frozen community repository, but this also brings the problem I cannot update the used programs as I am afraid it would attempt to replace the old KDE as well.
I know I can update Mozilla apps by downloading a static rpm and install with KPackage or Konsole and similar with LibreOffice. Not much friendly... I also discussed switching to other WM - but GNOME surely not, maybe Xfce (other ones have other issues).
Is it possible to somehow make KDE4 to behave like KDE3.5 in some ways? At least auto-mounting of flash drives etc.
i currently try to mount 4 internal sata disks using hal on a server installation?
i did
apt-get install hal and copied a .fdi script to /usr/share/hal/fdi/policy/10osvendor/30-storage-all.fdi
as far is i understand now i need a hal/dbus client
gnome-volumen-manager seems to be one
apt-get install gnome-volume-manager
now im stuck there is no such executable like gnome-volumen-manager thus, how does it work? how can i start it? how do i know if and why the .fdi script works or fails?
since its a server edition and its purpose should be a very minimized server install i dont want a GUI like gnome fully installed

View 5 Replies View RelatedI just installed Ubuntu server edition to my computer (brand new, no OS) and finished installation. In the terminal I used apt-get ubuntu-desktop to install a desktop interface.In my rig, I have two 500GB HDDs. I set them up through my computer BIOS as RAID1 drives, yet as I understand I still need to configure the Ubuntu software raid for it to work correctly. Unfortunately, I already partitioned my drives! I used the easy way (guided with LVM or whatever) and let it do it for me. Now, RAID1 is very important to me! Is there anyway to repartition the disks to use RAID1, or do I need to wipe my computer and reinstall Ubuntu?

Coming from Fedora, I had a Web/Mail/SQL server with 2 hdd's. One (sda1) was the one with Fedora on, and all backups were on sdb1.
Now, I started having issues with SDA1, so I started copying files to SDB1. 2 weeks later I noticed similar issues, and started copying new back files to SDB1. But once I started doing this I lost connection with the server.
Turns out that (in rescue mode) that I couldn't access SDA anymore, it couldn't even read stored data on it, etc. It didn't show up in fdisk anymore either.
So after a lot of trying I asked to replace the disk and started installing Ubuntu 10.04 LTS on it. After having installed everything, I tried to restore one of the MySQL backups that was on the SDB disk, but halfway I started getting errors. I stopped the restore and did some other stuff that I wanted to take care of first (apache2 config etc.).
I then tried to reboot to be sure that that was working as well, and then the problems started. I couldn't access the server anymore, and in rescue mode (which is a live cd my host provides, it's a dedicated server btw.) I didn't see SDB anymore.
I told them this and now after they told me that they managed to get it back, I went into the rescue mode and tried to recover bad blocks with the e2fsck command.
Code:
Trying to restore this bad superblock doesn't work. I've tried for almost all of them:
Code:
e2fsck: Attempt to read block from filesystem resulted in short read while trying to open /dev/sdb1
Could this be a zero-length partition?
What are the chances of TWO hard disks failing? Surely there must be something else wrong? Did a bad driver (which would be weird, since I didn't do any updates like that) screw both of my hard disks up in Fedora?
Also, I must note that when I tried to copy the backups from SDB1 to SDA1 (the new one). I got a read only (??) error, and some other I/O errors.
Just for information, I'll show fstab and mtab as well: /etc/fstab

View 8 Replies View RelatedI installed openSUSE 11.4 on HP elitebook 2560p few days ago (using KDE live CD). In general system is working fine, but steel I cannot resolve couple of really annoying issues: 1. I've created encrypted partitions for swap and home during OS installation. As result the system keep asking for passwords for each of encrypted partitions before show login screen. That leads to situation when I have to type 3 passwords during each boot/reboot. I was using the same configuration (swap and home were encrypted) on Ubuntu 11.04 and there both encrypted partitions were mount automatically with no password typing after login to the system. Could you please tell how I can configure the same behavior on openSUSE 11.4 ?
2. I've enabled auto screen lock after 5 mins being inactive. As result when I going back to laptop and to unlock the screen the system shows login screen (default login screen with user selection). But when user and password filled in I click login it creates entire new KDE session. Therefore all staff that was open before screen lock is gone. However old session is still in the system (it appears in output from 'w' command).
