Ubuntu Installation :: Error Message - Cannot Unmount SDA7
May 1, 2011
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 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 ran the ubuntu 11.04 live CD on my laptop that had an earlier version of ubuntu (9 maybe??). I really liked what I saw so I used the Install ubuntu 11.04 wizard and chose the option to override the earlier version. During the 'Importing document and settings' step a pop-up entitled Failed to unmount partitions. the body stated: migration-assistant needs to mount a partition, but cannot do so because the following mount partition could not be unmounted:
/dev/sda1
The only app showing on the taskbar is the Install. this is running from the live CD.

Using Clonezilla to try to backup (as image) my partition. It gives me an error saying, "Error! No unmounted disk are found! To use clonezilla to save or clone a disk, the source disk must be unmounted! "
So I tried doing these commands: url. (2nd post down) but they didnt recognize the unmount command. Plus when I did mount to see what was mounted, i did NOT see an sda1 or anything like that. I got a bunch of other stuff. ?
Is there another command to unmount?

unmount seems to hang forever.... I then usually would just unplug my drives. Then maybe 20 minutes later there is a pop-up error box saying
Code:
Unable to stop MyDrive" DBus error .... did not receive a reply. Possible causes include.

I'm trying to install ubuntu 10.10 on xp,but, after waiting around 2 hours per instalation I received a error message that says:" unbuntu installer : and error occurred: coercing to unicode: need string or buffer, none Type found. for more information see log file C:1customerlocals-1 empwubi-10.10-rev197.109. I tried on one particion make just for it then I even tried on xp on C: I even put it on a pendrive but my bios is old and do not provide for usb booting. The other thing I have to try is making a boot cd but for one reason or the other , my recorder do not want to recornized my cds- rw and right now I do not have any regular blank cds . That will be my next step. Note: Ubuntu appears installed on the the control panel "add or removed programs" but not in "all programs" list. I'm a novice on this so maybe the answer was posted but I couldn't find it. Looking ahead to try it and be part of the linux team.

I installed KDE 4.4 through Ubuntu's repos and then upgraded to 4.5 via backport PPA. I am unable to unmount any USB device. It keeps saying it's in use by another application. Even if I plug it in and do nothing, but then try to unmount, it gives me this error?

I have been using my desktop as a dual boot machine for several months now. The primary hard drive with windows on it died, and since we have been using ubunto 9.10 exclusively, I just removed the dead drive, changed the jumpers on the secondary drive to primary and did a clean install on the drive which presumably formats the disk before installing. When I try to boot from the hard drive i get the following message:
ERROR: no such device 2eb48bcb-7bb4-4080-b04d-fc32dec8c252

I am just now starting to go deeper than the surface of my computer so I am very much a beginner. I have downloaded Ubuntu 10.10 and have tried to install it by mounting the image and installing "inside windows." Next, upon reboot and selecting Ubuntu from the windows loader it eventually went to a colorful screen but stayed there... the first time I let it sit there for 20 minutes or so then restarted, uninstalled/reinstalled tried again... then I let it sit there for 3 hours, nothing. Next I tried to mount image and install "demo and full installation." This time upon reboot I choose Ubuntu from the windows loader menu and an error message came up. I will type it out below exactly as I see it because this is the same message that came up when a friend suggested I boot from a USB drive.
Busybox v1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash)

A couple of months ago I bought a new Dell laptop with Windows 7 pre-installed. Rather than strip the hard drive and go with Ubuntu exclusively, I left W7 on and set up Ubuntu 10.04 as a dual boot installation. All was well for a month or more and now suddenly W7 won't boot. The Windows error message I get is The boot selection failed because a required device is inaccessible I've purged and reinstalled Grub2 several times with no luck. Also tried Windows fixmbr which allowed W7 to boot but made Ubuntu inaccessible. Below is the output of the boot_info_script.

using 'ntfs-config' to make ntfs partitions mount on bootup so that I can access my data partition from Ubuntu. The first time I installed ntfs-config it would not run. I uninstalled and reinstalled it and then it ran, but it didn't seem to be responding very well. I attempted to tick the partition I wanted and set it to be writeable. After I closed the app ALL my ntfs partitions were mounted, even the windows and system reserved partitions, and when I attempted to unmount them I got the following error:
Unable to unmount Data
Error unmounting: unmount exited with exit code 1:
helper failed with
unmount /dev/mapper/isw_dfjjdefcdi_RAID5p4 is not mounted (according to mtab)
I tried rebooting. I tried uninstalling ntfs-config, then reinstalling it (now it wont run again). So I'm at a loss as to what to do. I simply want my data partition mounted on boot up and writable, not the others.
