General :: Moving /usr From '/' On Sda1 To Sda7 -- System Is Debian Squeeze: Sda7 Doesn't Mount?
Apr 1, 2011
I am running a Postgres server and after I did the whole installation I realized the Postgres data was set in /usr/pgsql/data. Sda1 is just 10 Gig so I decided to re-organize the partitions to be able to move /usr to say /dev/sda7 with a mount point as /usr. The / partition is on the only primary partition and the rest is on an extended partition. When I tried to resize the primary partition GParted did not give me that possibilty so I decided to move /usr
Original partitions:
sda1 / 10 G on primary partition this includes /usr /var and all others
sda5 swap 2 G on extended partition
sda6 /home 140 G on extended partition
So I did create another partition using Knoppix and Gparted the disk:here is the new picture:
sda1 / 10 G on primary partition this includes /usr /var and all others
code....
I did rsync to copy all the file to /dev/sda7/usr and then mv /dev/sda7/usr* /dev/sda7. I stop the postgres database and services then I mv /dev/sda1/usr to dev/sda1/poufusr . When I rebooted it reports errors from kbd files on /etc File not found. It brings me to a terminal (No GUI) I did a check with :#mount: nothing is reported about sda7
What am I missing ?

I figured I'd set up a test partition to test the waters before jumping head on to a full upgrade. I've created a new ext4 partition on my disk and marked it to be used as root for the install. Halfway through the installation an error message pops up saying it cannot unmount sda7 because it's in use, sda7 has nothing to do with the Natty install, it's the root partition of my main setup! I then aborted, rebooted and everything was fine with my main system, obviously the Natty install didn't take.

I have logical partitions on my drive numbered /dev/sda5 through /dev/sda14.I want to reclaim unused space from one of the partitions in the middle /dev/sda7. First I intend to resize /dev/sda7 by leaving the beginning of the partition as is and shrinking the end to create some unallocated space between /dev/sda7 and /dev/sda8. Then I would like to create a new logical partition in this unallocated space. My question is what will be the device name of the newly created logical partition? Will it be /dev/sda15 (I hope)? Or will it be /dev/sda8 and all partitions after this be renamed?
The GParted manual states that if a partition is deleted, all of the following partitions will be renamed, but it doesn't say anything specifically about renaming partitions after adding a new partition in the middle of a partition table.

I'm wondering I've read in some places that if people would like to move from a stable branch of Debian to the testing you can usually just replace the lines in sources.list with the testing release and update and then dist-upgrade. Is this true...and if so is it safe?

I have an older system that has been running testing for about 4 years. Originally I was running testing for several packages that were not yet available in stable. However, now that this system has a more crucial role in the network I have considered moving it to stable in hopes that it I can gain some insurance on it's uptime. It is important to note that I have never had a problem with the testing distribution and would be quite content to continue running it; I do want to know my options though.
I have not yet updated the system since the stable release of squeeze, I am considering to change my sources from testing to stable and just let apt take care of the rest. Anyone have any experience with such a thing? After searching Google I have found some solutions to force a downgrade, but that is really not what needs to be done here. I suppose I should have switched my sources to squeeze some time ago and this probably would have worked itself out.
A similar question is what happens a couple of years from now when another release happens. Have you had good luck updating from old stable to stable? I've run testing on several machines now for several years and have went through freezes and dist-upgrades several times with no major problems at all. Will I see the same stability if I move to the stable distribution?

I am using an embed linux application and trying to mount a USB device. The USB worked fine in windows. I then put it on my Linux box formatted (I hope correctly) And then tried to do the following to mount it
Code:
Disk /dev/sda: 4040 MB, 4040748544 bytes
255 heads, 63 sectors/track, 491 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I have a problem in my ubuntu 10.01 that it can't load a drive/volume in ubuntu. When I tried, it said: "Unable to mount location Error mounting: mount: /dev/sda1: can't read superblock". And when I boot my pc with 'Windows', it said : "UNMOUNTABLE_BOOT_VOLUME" under a blue screen. What can I do to solve this problem?

I installed Squeeze on an Acer Extensa 4420. My desktop is KDE. The problem is that I cannot mount DVD/CD in my laptop.
Here is my fstab
# /etc/fstab: static file system information.
#
# Use 'vol_id --uuid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

I turned on my laptop today and noticed a load of unfamiliar startup text so I knew something was wrong. Now whenever I startup my laptop, GRUB loads fine but when I try to start Ubuntu it says the following:
Quote:
mount : mounting /dev on /root/dev failed : No such file or directory
mount : mounting /sys on /root/sys failed : No such file or directory
mount : mounting /proc on /root/proc failed : No such file or directory
[code]....
so all I'm left with is this BusyBox command prompt. I'm on a live Ubuntu CD right now and if I try to mount /dev/sda1 either in the terminal (with the mount command) or with the GUI it just gets stuck.
Quote:
This will provide you with a list of your drives and partitions, you need to pick the one that your root file system is installed to, it will be something like /dev/sda1 but in my case I can't even mount /dev/sda1. When I run sudo fdisk -l heres what I get
Quote:
ubuntu@ubuntu:~$ sudo fdisk -l
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
[code]...
thats weird because I rebooted with a live Ubuntu CD and didn't even try to mount /dev/sda1 this time. The instructions were to then try to mount the drive from the GUI so heres what happens when I do that: it attempted to mount it for about a minute then gave me this error message When I tried again heres the error it gave me The problem seems to be that /dev/sda1 can't be mounted for some reason.
I don't know what that error message means and I don't know what else I can do to further diagnose /dev/sda1 and find out why it can't be mounted. Ordinarily I'd just reinstall Ubuntu but I have a couple of lab reports that I had saved on that partition so I'm in trouble if I can't figure out how to access the partition.
EDIT: At the end of that other thread someone recommends to use testdisk to recover the data from the partition. All I really need to do is get those lab reports back but I had them saved inside a Windows 7 guest on Virtual Box. Will this complicate matters a lot for me?
UPDATE: I tried to reinstall Ubuntu and it wouldn't work. Seems this is a bigger problem than I suspected. Does this mean my harddrive is corrupted? I can still use the Windows 7 partition but I take it that the Ubuntu installer not working is a bad sign.

I have a machine that has an integrated USB flash drive somewhere in it that I can not seem to mount. The OS knows it is there, as I can see it in the dmesg output, but the actual "node" in /dev doesn't actually exist. I'm baffled. Will you help me figure this out? Here's what I came up with so far. The disk is attached to the USB bus, used as a SCSI block device. In dmesg, it is referred to at one point as sdf, as well as under /sys/class/scsi_device. When I go check /dev, /dev/sdf does not exist!:
Code:
cat /proc/bus/usb/devices
T: Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=090c ProdID=1000 Rev=11.00

In a desperate attempt to play Tomb Raider, I have shrunk the /dev/sda1 with GParted in Maverick Live CD (the same one I used to install) then installed WinXP on it. Unfortunately for reason X, XP simply does not boot. So again I am in the Live CD, I have deleted the XP partition and am now trying to fix Grub2. In all the tutorials, you need to mount the normal partition. Which is what I am trying to do, but:
Code:
sudo mount /dev/sda1
mount: can't find /dev/sda1 in /etc/fstab or /etc/mtab
So there in nothing that I can do. Under "Places" I see my 489GB file system but I cannot mount it.
At least I am getting Internet through the Live CD and I always have Knoppix on hand.
EDIT: I should tell you that there is a boot flag on the /dev/sda1.

I have been learning Debian by using a virtual machine. After fine-tuning my installation procedure, I decided to copy that installation to my physical system. The hard drive already has another Linux based system installed. I plan to dual boot.After copying files I updated fstab and menu.lst.
The partition scheme between the virtual and physical environments are similar, but the partitions are not mapped exactly the same.Thus the Debian system on the physical hard drive fails to boot. I think the initrd created in the virtual machine is looking for the root file system on /dev/hda1 whereas on my physical drive the new location is /dev/sda7.How can I rebuild the initrd on the physical system? Or how can I build an initrd in the virtual system that will function on the physical system.I started to use the installation DVD in rescue mode, but I did not get too far.

I am trying to load Debian Squeeze from a net install CD on an old Wallstreet laptop. I am using BootX in OS 9.2. The problem I have is after the install gets to the bootloader section I tell it to continue without a bootloader, then open a shell so I can mount the Mac hard drive and copy the kernel and image file to the correct places. However, the Mac drive does not show up using df. I tried mounting to /dev/hda8 ( I know this is where the Mac HD is supposed to be) but get device not found error. I recall in previous version (etch) installing from full CD I had the option to install hfsutil, but I did not get that option with this netinstall CD. I changed the debconf priority to low hoping I would get more options of software to install but to no avail. Any ideas on how to get the kernel and image file to the Mac hard drive?

The problem I'm having didn't seem to be covered in other posts. Despite following what is supposed to be a straigtforward method, I am still unable to mount /dev/sda1.
Using Ubuntu 10.04 LTS LiveCD - Lucid Lynx
sudo /bin/bash
fdisk -lDisk /dev/sda: 250.1 GB
Disk identifier: 0xa08ea08e
Device Boot Start End Blocks Id System
[Code].....
I find it strange that fdisk sees the drive but mount doesn't.

Just installed 64 bit Squeeze on a new build system Athlon quad core 3 GHz and 4 GB of ddr3 in a Gygabyte GA-870A-UD3 rev 2.1 mobo and I can't mount the floppy disk. The onboard controller is an ITE IT8720 chip. The floppy is a generic internal drive - Sony I think.I know the hardware is ok as various versions of Puppy linux mount and unmount it ok and.When I saved I got the message "Unable to mount floppy dev/fd0 is not a valid block device" editing back and saving got "Unable to mount floppy0 dev/fd0 is not a valid block device".Can anyone point me in the right direction?

Actually, the /root- filesystem still gets mounted, for all the others I get the following message:
When I type
I get:
But this only happens when using my custom kernel (2.6.32.24). When I use the kernel which was automatically installed (2.6.32-5-amd64), the problem doesn't occur.
Is there a kernel option I should have turned on?
I checked the UUID-numbers from the error messages with the output of "blkid" - they match. The rootfs is on sda2 (which gets mounted without error) - so I tried applying the fstab mount options of sda2 to the other partitions - same problem still. what makes the root partition so special? Is it because it's defined by grub.cfg?

I want to move my old system to a new drive. Currently I have Debian installed with following configuration:
I have an encrypted system where everything is encrypted except /boot. Currently I've /boot and / installed on a 16 GB mSata SSD and /home on a regulard HDD. I've got a 500GB SSD for Christmas and want to move the whole system to the new SSD.
I just wanted to ask if I've got the process required to to this down:
1. backup root-directory (/) without and /boot /home using tar keeping file-permissions and owners to ext. hard drive
2. backup /boot and /home separately using the same method
2. replace HDD with SSD remove mSATA SDD.
3. boot via live-usb
4. create appropriate volume groups, partitions, setup encryption etc.
5. extract backups to appropriate partitions
6. chroot to old /.
7. edit fstab
8. reinstall grub
9. create new init ram img.
I'm pretty sure I've got steps 1.-6. down but I'm very shaky on what to do next.

I am trying to configure my test Squeze install on an older PC with LXDE desktop, and I can't seem to find anything which would enable me to mount a floppy.Then I tried to use the konsole as root mount -w /dev/fd0 /media/floppy0
But although this device and this mount point exist, nothing is mounted. I double checked with various floppies which I know have data on them and none of them are being mounted. The umount command would I expect be umount /media/floppy0 /dev/fd0...I tried searching the web and this forum and didn't find anything helpful. Can anyone help?

I got a rather big problem since an attempt to upgrade.My debian version is 8.0.I upgraded when apt proposed the change. I did that in two steps, with apt-get upgrade and then apt-get dist-upgrade, with the installation of a new kernel. I moved from 3.2.0-4-686-pae to 3.16.0-4-686-pae.Since the upgrade, I can't boot my system any longer.During the boot sequence, this message appears with a countdown (it's copied by hand) :
Code: Select all(1 of 4) a start job is running for dev-disk-byX2du
At the end of the countdown, the boot sequence starts again, and ends up on an invite to log in as root in rescue mode. I can't connect (maybe due to some azerty/qwerty issue, I got a French keyboard. I tried to type in "qwerty mode", with no success (the password is not prompted)).I can connect with the 3.2 kernel however, selecting it form the grub interface. I can't log in in rescue mode either, but with this kernel the boot sequence goes on and I can log as a regular user or as root, at the end of the boot sequence. There is no X, but the system seems to work.What could I do to make the system boot properly with the new kernel, or to go back to the 3.2 version ?

After using testing (now Wheezy) for almost a year and breaking my machine (latest nvidia broken packages), I went back to vanilla Squeeze (after updates, now at 6.02).Nothing from outside the stable repos; not even the nvidia driver (kept it at default and nouveau)Repo "deb http://www.debian-multimedia.org stable main non-free" enabled.It seems flash is not working with iceweasel; I either have a message which says "Cannot play media: you do not have the correct version of the flash player. Download the correct version," with a link to Adobe's site, of media appears in broken pieces.In order to keep my system "clean," I haven't downloaded anything from Adobe, and a search on this forum suggested installing flashplugin-nonfree or flashplayer-mozilla. Did both (can't have them at the same time), restarted, no joy.
~$ apt-cache policy flashplayer-mozilla
flashplayer-mozilla:
Installed: 2:10.3.181.26-0.1

Using coolbits allows for me to try to change it but it refuses to accept it, and even when i run it as root it still just acts like nothing has changed. It's not my laptop maker since i can overclock my gpu using rivatuner on windows so it's clearly not them trying to restrict me. I was attempting to restore teh clocks back to what the factory settings were from nvidia and not the underclocked settings that the oem put on it for the 3d settings and then reducing the 2d by ~10% to help it run cooler except when gaming.Has anyone been able to successfully use coolbits in squeeze? Or is there another nvidia overclockign tool out there besides nvclock since my gpu is apparently too new to work with it and i'm not going to risk it.

My net-book is working properly with Debian squeeze 2-6-32-5-686, only the wlan does not work. After typing lsusb I have got the message: lsusb : Bus 002 Device 002 : ID 160a:3184 VIA Technologies, Inc. VIA VNT-6656 [WiFi 802.11b/g USB Dongle]
So I obtained the driver package : VT6656_Linux_src_v1.19_12_x86. I followed the instructions ( make install... ) - but the result is only a lot of error messages. Mayby I am using the wrong driver package for the squeeze kernel - I don't know.
