I have 2 internal SCSI drives in the box. I also have an external USB HDD that's almost always there, so it's in fstab to be mounted somewhere.
When I boot with the external connected, here's what I get:
External = sda
Internal SCSI-1 = sdb
Internal SCSI-2 = sdc
Without it:
Internal SCSI-1 = sda
Internal SCSI-2 = sdb
The SCSI drive's are a RAID setup, so if I boot without the external I have complete RAID failure.
Reboot and select proper boot device or insert boot media in selected boot device and press a key. I got this error after: Reducing my Windows 7 partition by about 100gb. Creating a new partition (100gb) and copying my Ubuntu partition (10gb) to the new partition. After it was copied, and pasted, the original partition was deleted. I now had two partitions a new 100gb Ubuntu partition and a 600gb (or so) Windows 7 partition.
All of this was done using a bootable USB with Ubuntu 10.10 and GParted partition editor. Now when I boot I get the "Reboot and select proper boot device or insert boot media in selected boot device and press a key." error.
I installed ZTE MF 626 modem in my F10 with kernel 2.6.27.12-170, i run usb_modeswitch and so far things happened normally. Watching through /var/log/messages it says that F10 detects two port device for this modem: ttyUSB1 and ttyUSB2, and in the sequence it disable port ttyUSB1 BUT Network Manager still set this port.I mean, when i connect via wvdial appointing to ttyUSB2 i get connection, but Network Manager fails to do it appointing to ttyUSB1. How to change device port in Network Manager?

how to change the name of any device (usb drive) instead of assign by system ,i am using fedora 10
View 1 Replies View RelatedI want to be able to change the root device, say from sda to sdb, so that I am able to remove sda. I don't believe this is possible with chroot, as I am changing the root folder to a mount point that exists on sda (sdb is not on fstab), so removing it would lock up the system.
Any thoughts how I can do this?
Installed ubuntu 10.4 over previous ubuntu on Intel 945G. After installation and reboot the system does not boot: "no bootable device - insert boot disk and press any key".
Installation was done from USB-stick, prepared by UNETBOOTin. I have two HD's, one used for system + storage, another one just for storage. I manually deleted previous system partitions of previous ubuntu install in system HD. The system HD had about 1/3 of free and unallocated space for system partitions, which ubuntu installer created during the installation.
I tried to reinstall grub from bootable USB-stick and it succeeded but it did not help. The system is still not bootable.
I have used ubuntu for years and never happened something like this. Am I missing something or is ubuntu missing something???
HW failure is ofcourse possible but I am quite skeptical about it because Live ubuntu from USB-stick works well.
i had a working multi-boot system, vista on sda1,2; swap sda3; ext=sda4; ubuntu sda5; fedora sda6; data sda7 - i mount the data partition when using all of the linux releases so i don't have to have multiple copies of music, docs, etc. everything has worked fine until yesterday. i tried to install fc12 on sda6, replacing fc11. it required me to format sda6 as ext4. i wasn't sure where i had grub installed, but have a backup of menu.lst in data (sda7), so figured i could let it install to mbr or wherever it wanted to by default. when the install completed and i reboot, i get a black screen and these messages: CLIENT MAC ADDR: 00 19 XX XX XX GUID: XXXXX PXE-E53:
No boot filename received
PXE-M0F: Exiting Intel Boot Agent.
No bootable device -- insert boot disk and press any key I tried reinstalling fc12, same exact errors. I then thought maybe the problem had something to do with ext4 partition mixed in with ext3's, so i installed mepis on the sda6, and let it write grub to mbr (i think, not really sure where it wrote it). anyway, i still get the identical black screen. no grub type menu or anything. the screen used to show "DHCP for a few seconds", but doesn't anymore after i disconnected the ethernet cable.........
Without going into a lot of the reasons, I have a bootable program on a USB stick that i would like to 'boot' when debian is starting up (or after it completes, or whenever it makes sense to do it). My MB does not support a USB boot, I've removed the floppy and CD so I can add additional HDs (its a small box but well ventilated).
Another option I have is to use my bios 'network boot' option, but I have no clue how to use it and the only description in the mb manual says "Allows system to be booted over a network" In network boots, *usually* one is given an option of specifying a device address, and the network boot executes a boot protocol (e.g. bootp), and the boot image file is downloaded to the target, stored and run out of RAM. No evidence of this behavior is exhibited when the network boot option is selected in the bios...
In Linux, Is there a way to remember/change a path to a USB device? In my case, I need linux to remember that my USB serial adapter will stay on /dev/ttyUSB0, but when I unplug it and plug it back in, it switches to /dev/ttyUSB1. I'm using a debian-based distro(mint)
View 1 Replies View RelatedAfter I reboot my Ubuntu 10.04.2 LTS l machine my device paths change (even the boot drive) and this causes havoc on my two RAID5 arrays. The device paths change and causes a mismatch in my fstab and I have to manually mount both RAID arrays every time. It's quite frustrating and annoying and I would love for it to stop. This even happens for the boot path.
Example: my boot path is /dev/sde5 I reboot my machine and my boot path changes to /dev/sdm5
Why does this happen? And more importantly how can I stop it from happening so it stops messing with my RAIDs?
I'm not sure what to make of this. I have setup an Ubuntu 10.10 server with two software raids.md0 is a four disk raid5 - 3TBmd1 is a two disk mirror - 300GBI think I have a drive failing (and am going to replace it regardless, but I have to take an outage), what appears to happen is it comes on-line with one id (/dev/sda) then something happens AFTER the rebuild completes and the drive changes to another id (in this case /dev/sdh) and puts the array in a failed state.Is this some sort of protection mechanism to prevent degradation to the array? When setting this up, presumably before the disk started to fail, Ids seemed to jump from reboot to reboot and caused me all kinds of issues.Also, neither device appears to return info after the change.
Code:
bwoods@MediaServer:~$ cat /proc/mdstat

I currently have a Windows XP OS which i want to dual-boot with Ubuntu Linux 10.10 . I put the disk in the drive and chose the option to install Linux through Windows. But it hangs in the middle. I am also unable to change my BIOS settings due to which i can"t change my boot preference. My first Boot is the HDD. I want to change it to CD-ROM. Any suggestion? I also have another PC where i can boot through the CD...I tried installing there by booting from the CD but i get this error message after seeing the purple Linux screen with the loading dots. "(Process:286):Glib warning**:getpwuid:failed due to unknown user id (0)
P.S.- I am not able to see any options while the boot is going on
how do you change the default audio output device if you have multiple sound cards?
View 14 Replies View RelatedI recently bought a logitech headset which is working very nice, the thing is that I cannot make it my default device when I plug it in. I edited /etc/modprobe.d/alsa-base.conf to make snd-usb-audio the default card but it only works when the computer is turned on with the headset plugged in. A workaround is to plug it and then "alsa force-reload" but I find it very ugly plus it kills all apps using audio and leaves the volume indicator unstable.

I recently compile Kernel 2.6.34 (to fix the AMD PowerNow issue with 1055T processor, and it worked!) However, the device
/dev/shm
starts up at boot as Read-Only.
Google Chrome requires this device to be user-writable, or it won't start up. Presumably, the stock kernels (and all that are updated) have it set to User-Write. I have not noticed any other ill effects with the permission being read-only. If I do:
sudo chmod a+w /dev/shm
Everything will work from there, but each time I reboot, I have to do that. How do I make that permission-change permanent?
For example /dev/loop*, /dev/raw/*, etc., they are automatically reset to root/root after rebooted.Change the owner/permission of device files maybe not a good idea, though. I just want to know if it is possible and how?
View 1 Replies View RelatedI built a Raid5 volume with 3 SATA II hard disk drives. Further I have a system disk conected through IDE. During the first setup the IDE disk becomes sda, the SATA II disk sd[bcd] respectively. Now, sometimes the device names change after reboot - why ever... E.g. one of the raid5 disk become sda and so I got an error message during the boot procedure regarding the raid set. Curious, when the system is up and I stop and restart the Raid5 volume it comes up and runs fine. Because I'm currently at work I can't post any more detailed config files at the moment.

I recently installed a new sound card, and I need to find out how to change the default device. Currently, I'm dual-booting Windows, and I had re-enabled the on-board audio in the PC's bios.

After asking on both this forum and the Fedora forum, I felt it was safe enough to install a copy of Fedora on my working-well openSUSE drive. I have a 1 TB drive, partitioned as follows:
I did an install of Fedora 13, was VERY careful to set up the installer to put it's files in the partitions I wanted, although I did let it mark the partition as active, feeling it may have to boot during the installation process.
I had grub installed in the root of the partition rather than the MBR for both systems.
When Fedora finished installing, I rebooted the system only to find that it wouldn't. I got the dreaded "No Boot Device" message.
So, I started the 5 hour process of booting with the parted magic disk, booting with a Gentoo live disk (only one around), monkeying with the install parts of the openSUSE and Fedora disks, swapping drives to Windows to download openSUSE Live CDs (yes, both) and searching the forums and various other web sites for some poor bloke who did the same stupid whatever it was I did, and finally, as I was using fdisk on the Gnome Live CD, I noticed the warning message stating that fdisk would not work on a drive that was partitioned with the GPD format.
Notice that I have 5 partitions? That is not a typo on my part, I used the GPD format when I set it up so I could do what I did without using "imitation" partitions.
When I used parted (the command line editor on the Gnome Live CD) to change the active partition, everything started working again! Well, at least I can boot the openSUSE system, the most important thing.
It is my suspicion that the Fedora install uses fdisk to do it's work, and fdisk just mucks up a GPD formatted disk. Not the information, just the part of the drive that holds the partition table. Perhaps just the flags section. I don't know enough to say with any certainty.
I didn't change the drives parameters during the installation of Fedora, so I don't know of it even offers the GPD partitioning option. If not, I can understand how this sort of thing could happen.
Still....So now all I have to do is make the grub menu, the one installed with openSUSE, boot the Fedora installation on the next partition. Seems simple enough.
Dual Booting my laptop and unable to change the Boot Records on the drive. Not because I dont know how, but my primary OS will fail to boot(win7).
I have drive partitioned as follows...
sda1 = Win7 system (default install)
sda2 = Win7 Main (default install)
sda3 = swap
sda4 = Extension (I think thats what its called)
sda5 = / (ext4)
What I need is a boot cd or perferably Grub installed on a 256MB Thumb drive with the options to load the installed system from sda5.
