Debian :: Grub On Two Disks - Conflict?
Aug 14, 2015
When booting, the grub menu appears and allows me to boot from the internal hard disk (sda) any OS there, such as WHEEZY (sda9). On the external disk (sdb) there is a dd'd copy (not an installation) of SQUEEZE (sdb1), which at one time was on sda but which has different partition assigments listed in its grub.cfg than the current ones shown below for sda.
Code:
Select allNAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 111.8G 0 disk
├─sda1 8:1 0 23G 0 part
├─sda3 8:3 0 1K 0 part
├─sda5 8:5 0 3.9G 0 part [SWAP]
├─sda6 8:6 0 11.7G 0 part
├─sda7 8:7 0 19.5G 0 part /home/norman/data
[code]....
Can I manually boot the SQUEEZE copy on sdb1 using grub commands (set, linux, initrd, boot) without disturbing the WHEEZY and other OSs on sda? Or will they be disrupted?Alternatively if for example JESSIE is installed in sdb3, for example, can it be booted similarly without affecting the installations on sda? I hesitate to try this by trial and error because of the work and time involved in rebuilding messed-up OSs to their desired configurations.

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)
(a new server,2 CPU 8 core and 8 gb ram)
1000000+0 records in
1000000+0 records out
1024000000 bytes (1.0 GB) copied, 12.9662 s, 79.0 MB/s (I have not used this server yet) (hw raid1)

I upgraded from Jaunty - Karmic - Lucid in very quick succession (and surprisingly succesfully too) but have encountered a slight issue with Grub on booting up since the upgrade.I had a removable HDD plugged in when the upgrade was going on. Now when I boot up Grub stalls and comes up with a message that its looking for SDD5 or something. I can tell it to skip this, but I'd rather it wasn't appearing at all.How can I edit Grub to tell it what disks it should and shouldnt be looking for?

I have a server with two gig-e ports, eth0 and eth1. When eth0 the only port that is connected to a network it will get online ok. It is the port used to connect to the internet. eth1 is used for PXE / TFTP / DHCP server for a private network. eth1 will serve ip's ok. The issue is when both are connected at the same time. eth0 to our LAN, and eth1 to the private network; eth0 does not ping or load pages in firefox. eth1 will still serve ips'. Is there any reason why eth0 would stop working if eth1 is connected to a switch? eth0 ip is 192.168.10.110, eth1 ip is 192.168.1.1 different subnets.

For some time I was trying to run an asp.net program in Linux using Mono with no success. So I installed WinXP IIS webserver in VirtualBox. This created a conflict with the apache webserver on my main server. My router will direct the user requests to only one of them. Is there a way to direct the aspx.net users to the VirtualBox IP and the other users to apache on the same domain? I tried to do that with bind and a php redirect page but failed.

I have an ASUS A8N-SLI board with an nForce4 raid 1 setup hosting a Windows 7 array over two 500GB disks. I have a third SATA drive with opensuse 11.3 installed and working perfectly. By changing the boot order in the BIOS, I can alternate which system boots at startup. What I want to do is set up a dual boot configuration... I don't care how, but I want a screen that asks me which OS to use, preferably defaulting to Windows so my wife can stil check her email without calling me at work.
I thought the easiest setup would be to set the LINUX drive as the primary device and then add then chainload the Windows disks, and set them first in the boot queue. That way, without any intervention, the system would pause for 8 seconds and see if I wanted to boot LINUX, then boot Windows if I didn't do anything.
The problem is, I can't figure out how to add Windows to the GRUB menu and recognize it. All of the documentation I can find seems to assume that your Windows and LINUX partitions are on the same disk, which mine are not.

While using monofree package, trying to install mono presents a conflict but aptitude just erases monofree and installs mono anyway.Is there a way to force the system to keep monofree and show an error when I try to install something that conflicts?

I got a new laptop the other day, repartitioned it and installed Lenny. The wireless did not work. From some searching, I decided that I have the 14e4:4727 broadcom chipset. The driver I need is partially supported by the 2.6.33 kernel. I installed squeeze and downloaded the 2.6.35-7 kernel from kernel.org Then compiled it with the debian 2.6.32 kernel config file. Once it was done I installed the kernel deb files, and restarted it.
Kernel 2.6.35.7 Compiled with commands
make oldconfid
make menuconfig
export CONCURRENCY_LEVEL=2
make-kpkg clean
fakeroot make-kpkg --append-to-version "-hermes" --revision "10-5-2010" --initrd kernel_image kernel_headers
[0.433831] PCI_root PNP0A03:00: address space collision : host bridge window [mem 0xafffffff-0xdfffffff] conflicts with PCI bus 000:00 [mem 0xd0000000-0xffffffff]
And it seems to hang until I manually hold the power button to shut it down.
Before I compiled my own kernel I tried to use the liquorix-2.6.35-amd64 kernel with the same result. Am I doing something incorrectly?
Computer: DELL Inspiron m5010
4g ram
phenom 2 triple core
ATI Mobility Radeon HD 4250
I have been using linux primarily for a year or two.

I'm running debian 2.6.32-5-amd64 and have spent an interesting day trying to get nvidia-glx running...What appears to be happening, is that installing nvidia-glx uninstalls X.I've tried various installation methods (Synaptic, apt-get, module-assistant) and the final result seems to always be /usr/bin/X not found.Re-installing X blows away nvidia-glx.The symptoms look a lot like this post: viewtopic.php?f=7&t=45188Is it possible that this problem has returned?

I have Xfce installed on wheezy, and I was planning on installing some KDE components for kicks. When I tried to install kdebase-workspace I got this error from aptitude The following NEW packages will be installed:
[Code]...
The following packages are RECOMMENDED but will NOT be installed: kinfocenter plasma-scriptengines policykit-1-gnome polkit-kde-1 upower 0 packages upgraded, 30 newly installed, 0 to remove and 49 not upgraded.
Need to get 78.5 MB of archives. After unpacking 137 MB will be used. The following packages have unmet dependencies: xfce4-notifyd: Conflicts: notification-daemon but it is not going to be installed.
If it's not going to be installed, then where is the conflict? I've seen "Depends: X but it is not going to be installed", which makes sense. The only solutions are to remove xfce4-notifyd or to keep most of the KDE stuff uninstalled. apt-get also wants to remove xfce4-notifyd. Edit: Ok, it looks like both plasma-widgets-workspace and xfce4-notifyd provide notification-daemon, but I still don't understand why the aptitude error doesn't tell me that xfce4-notifyd conflicts with plasma-widgets-workspace instead of notification-daemon.

How do I reconfigure grub when adding a disk to a machine where both disks have their own MBRs? I have two volumes:Disk 1 - actually mirrored RAID-1 drives managed by ICH9R on the motherboard Disk 2 - a single drive managed by ICH9R on the motherboard, but without RAID. Disk 1 is the "old" disk containing WinXP on the first partition. The MBR of Disk 1 was created by Windows. Disk 2 was built on the machine while Disk1 was unplugged. Disk2 has Win7 on /dev/sda1 and Fedora 12 on /dev/sda7. Obviously, Disk 2 has grub installed on its own MBR.
When I plug-in both Disk 1 and Disk 2 at the same time, I would like to reconfigure grub so that it gives me the option to switch between WinXP on Disk 1, Fedora on Disk 2 and Win7 on Disk 2. (I may also want to install Ubuntu on another partition of Disk 1, but that's a separate issue.) The problem is that when I plug in Disk 1, Disk 1 becomes /dev/dm-0 and Disk 2 becomes /dev/sdc (instead of /dev/sda as when I installed it). (I don't think I can switch this order because I'm worried that Windows will become confused.) So, how do I keep all partitions the same and get them all to work from grub? On which MBR will I need to install grub? How do I configure it to see all 3-4 of my operating systems? Do I fix grub from the Fedora LiveCD?

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?

I've been all afternoon trying to install Ubuntu Lucid on my fakeRAID 0 configured (2) HDDs and am unable to set GRUB up. The fake RAID setup is provided by Intel Matrix Storage Manager, it is correctly enabled and the BIOS is also correctly set up -- in fact, I've managed to install Windows 7 with no significant hitch. After struggling with partioning the drives (had to follow advice I found on a very helpful guide online [0]), creating the filesystems AND getting Ubuntu's installer to actually do what it is supposed to do, I now cannot seem to set GRUB up. My system, as it stands, is unbootable at all; via live CD only.
This is how the RAID0 dev is partitioned:
Code:
# fdisk -l /dev/mapper/isw_ecdeiihbfi_Volume0
Disk /dev/mapper/isw_ecdeiihbfi_Volume0: 1000.2 GB, 1000210694144 bytes
255 heads, 63 sectors/track, 121602 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 131072 bytes / 262144 bytes
Disk identifier: 0x6634b2b5 .....

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?

Earlier today I installed Debian Squeeze with Gnome off the 64-bit CD 1. I didn't have my ethernet connected and ended up only getting a pretty minimal desktop with not much installed besides Gnome. This bothered me, as I thought I could install the whole desktop off the CD. I reinstalled, this time with my Ethernet connected. This time it took much more time and gave me what I wanted, a complete desktop. Simply put, what do I need to install everything that I currently have without having my Ethernet plugged in?

I am running Debian 3.2.0-0.bpo.2-amd64 on hyper-v, my / volume ran out of space and is sitting at 100%, I have extended the disk size on hyper-v, however when I go to Fdisk I see duplicates of each disk.
I have total of 2 vhds on the vm, so I see 4 disks under fdisk. Here is the output of fdisk
root@apachevm:~# fdisk -l

I'm trying to do some RAID managing with mdadm. I would like to sync my spare disk and then remove it from the array for making a backup out of it with dd command (the best way i can think of to get the current image of the whole system as it can't be done using the active RAID as source, because is constantly in use and changing). So, I have RAID1 array with 1 spare and 2 active disks (configuration listed below). Now I would like to force spare to sync and then remove it from array, although not faulty.
However, mdadm man page states:
"Devices can only be removed from an array if they are not in active use. i.e. that must be spares or failed devices. To remove an active device, it must be marked as faulty first."
So, I'd have to mark a disk as faulty (which it is not) to be able to remove it from array. There seems to be several people reporting that they can't remove this faulty flag accidentally given to a drive. And mdadm does not give direct for such operation. Isn't there a way I could remove and add disks whenever feeling like it?? One way would be open the cover and physically remove the disk. I'm not taking the risk, though. System is almost always in use, so there is not much chance for me to power off for temporary disk removal.
RAID CONFIGURATION:
~# mdadm --detail /dev/md0
/dev/md0:
Version : 00.90.03
Creation Time : Fri Aug 4 17:38:26 2006
Raid Level : raid1
Array Size : 238950720 (227.88 GiB 244.69 GB)

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
Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Installing two scsi hard disks on a debian system.
It is a physical old HP machine (netserver lc2000) with a fresh debian wheezy 7.0.8 installed.
It has two scsi hdds (73GBs) that I don't know how to add to the system so I can partition, format, mount, etc.
This is what I have tried so far:
1. dmesg output
Code: Select all# dmesg | grep scsi
[ 2.173909] scsi0 : pata_serverworks
[ 2.174377] scsi1 : pata_serverworks
[ 2.417276] scsi 0:0:0:0: CD-ROM LITEON CD-ROM LTN485S JKF1 PQ: 0 ANSI: 5
[ 2.622195] sr0: scsi3-mmc drive: 48x/48x cd/rw xa/form2 cdda tray
[ 2.623194] sr 0:0:0:0: Attached scsi CD-ROM sr0
[Code] ....
2. lsscsi output
-I installed lsscsi and here is the output:
Code: Select all# lsscsi --device
[0:0:0:0] cd/dvd LITEON CD-ROM LTN485S JKF1 /dev/sr0
[2:0:0:0] disk HP Net Mirror V1.0 /dev/sda
[2:2:0:0] disk HP 9.10GB C 80-P94N P94N -
[2:2:1:0] disk HP 9.10GB C 80-P94N P94N -
[Code] ....
3. force scsi scan
-I tried to use this command to force a rescan for the hdds, but nothing happened:
Code: Select allecho "- - -" > /sys/class/scsi_host/host3/scan
-no errors, but log says nothing
-tried the above with host0 - 4, same result
4. fdisk -l
Code: Select all# fdisk -l
Disk /dev/sda: 9098 MB, 9098887168 bytes
255 heads, 63 sectors/track, 1106 cylinders, total 17771264 sectors
Units = sectors of 1 * 512 = 512 bytes
[Code] ....
5. tried to specifically add one device but it didn't work:
Code: Select all# echo "scsi add-single-device 2 2 8 0" > /proc/scsi/scsi
-bash: /proc/scsi/scsi: No such file or directory

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!

I have XP and win 7. I want to triple boot with Debian.When I install, grub finds win 7 and XP and says everything should be fine, but then when I boot, only debian appears.This was fixed by doing update-grub2 after logging in.Now, I have win 7 bootloader as an option. However, when I boot into XP, and then reboot, grub disappers. he screen just says welcome to grub and then a blinking cursor.

One 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).
