ubuntu - Probelems with mount.

I was not sure about where to post this thread, since its related to hardware..
If anyone feel like moving it, please do so.
I've also searched for related problems, but i could't seem to find any.

Additional Information in case it might be relative:
It is a fresh install of ubuntu with post-installed KDE and a dist-upgrade.

uname -a == Linux nutz 2.6.10-1-386 #1 Fri Mar 11 02:31:59 EST 2005 i686 GNU/Linux cat /proc/version == Linux version 2.6.10-1-386 (dilinger@mouth) (gcc version 3.3.5 (Debian 1:3.3.5-8)) #1 Fri Mar 11 02:31:59 EST 2005 glib-config --version == 1.2.10 mount --version == mount: mount-2.12p

Ok, straight to the case:
I wanted to upgrade my kernel from 2.6.8 -> 2.6.10-1-386, because my nvidia drivers wouldn't install on the 2.6.8 kernel. (I used apt)
So after i upgraded the kernel, the nvidia drivers installs perfect, but then another problem occured:

I've added the line below into /etc/fstab:
/dev/hdb1 /disk/1 ext3 defaults 0 0
But when i try to do "mount -a", i get this error:
root@nutz:~ # mount -a
mount: /dev/hdb1 already mounted or /disk/1 busy
I also get this error when I try to do the mount completely manually:
mount -t ext3 /dev/hdb1 /disk/1

As you probably can see below, this is not true:

root@nutz:~ # cat /proc/mounts rootfs / rootfs rw 0 0 /dev2/root2 / ext3 rw 0 0 proc /proc proc rw,nodiratime 0 0 sysfs /sys sysfs rw 0 0 /dev2/root2 /dev/.static/dev ext3 rw 0 0 tmpfs /dev tmpfs rw 0 0 devpts /dev/pts devpts rw 0 0 tmpfs /dev/shm tmpfs rw 0 0 usbfs /proc/bus/usb usbfs rw 0 0

"lsof |grep /dev/hdb1" gives a new line. (Meaning that it could't find anything)

root@nutz:~ # df -h Filesystem Size Used Avail Use% Mounted on /dev/hda1 113G 85G 22G 80% / tmpfs 253M 4.0K 253M 1% /dev/shm tmpfs 10M 2.8M 7.3M 28% /dev root@nutz:~ #

root@nutz:~ # ls -ald /disk/1/ drwxr-xr-x 2 root root 4096 Mar 24 11:36 /disk/1/ root@nutz:~ #

"lsof |grep /dev/disk/1" Also gives a new line..

root@nutz:~ # umount /dev/hdb1 umount: /dev/hdb1: not mounted root@nutz:~ #

Does anyone know what my problem can be related to? And most importantly, does anyone know how to fix this?


nohope@EFnet.

Could you post your fstab file. Also make sure you have permission to access your disks by adding yourself to the disk group.

Cheers

# /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 /dev/hda1 / ext3 defaults,errors=remount-ro 0 1 /dev/hda5 none swap sw 0 0 /dev/hdd /media/cdrom0 udf,iso9660 ro,user,noauto 0 0 /dev/hdb1 /disk/1 ext3 defaults 0 0 /dev/hdc1 /disk/2 ext3 defaults 0 0

This is my fstab.

Nothing really happened when i added myself to the disk-group.
Problem is still there.

If you need anything else, please just tell me.
I can't figure out what the problem might be.

After adding yourself to the disk group, you need to log out to make this effective, and I assume you have done this by now. Next quirk that nobody seems to mention is that if anything is referencing the hard drive or the folder while you are mounting it, then it spits out the message you are receiving. This includes a file manager opened at the folder you are trying to open.

Two things I would suggest you do and a trouble shooter.

1. open up Kwikdisk and have a look at the mounted status
2. make a desktop shortcut by right clicking on your desktop and create new link to device. This will allow a little more control via GUI.

Close everything down, and have just the terminal up if you wish. Try mounting via the icon on the desktop. Check Kwikdisk to see what it says.

Also - just to check - you do have a folder /mnt/1 that you created which the fstab is referencing. Otherwise you will get this error again.

Let me know how it goes :-)

Cheers

I have tried everything. But it doesn't work.
Is it possible to work around a EBUSY-signal ?

Troubleshooting time.

As a point of interest, does your bios show two drives or one?

Try renaming your fstab entry for /mnt/1 to /mnt/hdb1 and rename your folder to match. Try to mount again using the CLI. If this works yipee...... if not step two.

If you have a live cd, try to mount the hard drive, if you can..... If you dont have a live cd... why not? Ubuntu ships them for free!!!

If mounting your hdb1 with a live cd fails, I would say you have a hard drive issue. If you can mount the hdb1, try to back up your docs.

Let me know how you go.

My bios does show two harddrives, dmesg does too.
It didnt work editing fstab.

I cant seem to find my live-cd with ubuntu. I know it is here somewhere..
locate "/../IRL" -iname "ubuntu" ..

When i boot with the ubunut live-cd the partition mounts perfectly, but then again. my nVidia-drivers wont work.

There must be an error whilst mounting during boot. Try changing your fstab entry for hdb1 to

/dev/hdb1 /disk/hdb1 ext3 noauto,users,rw 1 1

Reboot and then try to mount hdb1 manually. The default signal will try to mount automatically during bootup, but by changing to noauto, it will remain unmounted. If you get an error message whilst mounting, it should be different, and also should show you the real cause of the problem.

Nvidia may not be a part of your kernel on the live cd. It would be upsetting for all those that use Readon or ATI to have nvidia loaded. That would be my assumption.

A few moons ago I tried Ubuntu. You are a sudo user by default if I remember but have you tweaked your settings to allow yourself to become root?

It doesnt work. It still gives the same error..

Hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm!!!!

try

chmod 777 /dev/hdb1

mount -t ext3 /dev/hdb1 /mnt/hdb1

df -ah

highlight all and post results please.

also have a squizzy at

man:/usr/man/man8/mount.8.gz

Just cut and past in Konqueror address bar or another file manager that you may use.

root@nutz:~ # chmod 777 /dev/hdb1
root@nutz:~ # mkdir /mnt/hdb1
root@nutz:~ # mount -t ext3 /dev/hdb1 /mnt/hdb1
mount: /dev/hdb1 already mounted or /mnt/hdb1 busy
root@nutz:~ # df -ah

how is the hd mounted?
Is it a new hd installation after you installed Ubuntu?

This message is created because something is trying to reference the hd or it is already mounted. You sound rather apt with the cli so I am not going treat you like a newbie.......but I must ask, are you sure hdc is not mixed up with hdb?

from you fstab

/dev/hdc1 /disk/2 ext3 defaults 0 0

I dont see this fstab entry showing under you df -ha output

Also your df -ha output says

tmpfs 10M 2.8M 7.3M 28% /dev

here is mine

tmpfs                 251M  764K  250M   1% /tmp

When you mount the HD with your live cd, what does the output of #df -ha say?
To get to the bottom of this, I will need to know a little more history ie how did you format the HD to ext3 etc.

If you were to enter

cfdisk /dev/hdb

can you see your hd? Hit 'q' to exit the screen

Give this a go and let me know any oddities

Cheers

Sorry guys. The problem was solved in the best way it could be solved:
I installed Debian :-)
