tunasashimi · 07-04-2005, 06:39 PM

Latest ubuntu live cd won't mount my Suse 9.1 reiserfs disk, any ideas why?

How are you mounting it?

Which commands are you using?

Give some details.

tunasashimi · 07-05-2005, 02:28 AM

mount /dev/hda4 /mnt/z

says its busy

not in mtab
or fstab
and doesnt show up when you type "mount"

mount -f puts it in mtab but its unreadable

mount -v shows "trying reiserfs"

mount /dev/hda4 /mnt/z -t reiserfs -o ro

Useless...

Linux can be so annoying sometimes

HOW about MORE details, like "Invalid filesystem" or Something other than SHIT like
"hdb4 is busy" BAUUHH

I am root, btw.

Code:

mount -a

should tell you if there are any bad lines in fstab.

duffmckagan · 07-05-2005, 02:37 AM

Try this as well.

Code:

sudo /etc/init.d/dbus-1 restart

PS hda1 and hda2 are ext2 and mount just fine

Let some expert help you. I won't interfere anymore.
I can't deal properly with frustrated people.

Thanks for trying... Hmmm.. interesting reply. I still havent figured it out.

StianLangvann · 07-12-2005, 08:00 AM

http://www.linuxquestions.org/questi...t=ubuntu+mount
The exactly same problem

Anyways. Try to strace the problem
(strace mount /dev/hda4) - and put it here or some other place.

Are you sure it ain't mounted already? I know that my old Mandrake-distro mounted everything into /mnt/, but my Ubuntu-distro mounted my NTFS-disks into the /media/-folder...

I updated to latest kernel using apt-get and am now also having this issue. Something is wrong with ubuntu/debian. I have been a linux server administrator (RH 6.2 on) for a very long time now. I have mounted a lot of drives ; ) Tried to mount drives that were busy too. This one's not...

I am trying to mount /dev/sdb to /media/windows. It mounted under redhat fine.

From the ubuntu site:

Code:

Q: How to mount Windows partitions (NTFS) on boot-up, and allow all users to read only?

   1. Read General Notes
   2. Read How to list partition tables?
   3.

e.g. Assumed that /dev/hda1 is the location of Windows partition (NTFS)
     Local mount folder: /media/windows

   4.

sudo mkdir /media/windows
sudo cp /etc/fstab /etc/fstab_backup
sudo gedit /etc/fstab

   5. Append the following line at the end of file

/dev/hda1       /media/windows  ntfs    nls=utf8,umask=0222 0       0

   6. Save the edited file (sample)
   7. Read How to remount /etc/fstab without rebooting?
-------

I am using SATA drives so mine are /dev/sda and /dev/sdb. It's not a mirror set.

$sudo mount -a produces:

Code:

viza@anon:/$ sudo mount -a
mount: /dev/sdb already mounted or /media/windows busy

$sudo mount produces:

Code:

/dev/sda1 on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev on /.dev type unknown (rw,bind)
none on /dev type tmpfs (rw,size=5M,mode=0755)
usbfs on /proc/bus/usb type usbfs (rw)

so it's not mounted

here is fstab (only one partition so no number necessary)

Code:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/sda1       /               ext3    defaults,errors=remount-ro 0       1
/dev/sda5       none            swap    sw              0       0
/dev/hdc        /media/cdrom0   udf,iso9660 ro,user,noauto  0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0
/dev/sdb       /media/windows  ntfs    nls=utf8,umask=0222 0       0

If I tack on a 0 to /dev/sdb in fstab and rerun mount -a

Code:

viza@anon:/$ sudo mount -a
mount: special device /dev/sdb0 does not exist

lsof | grep windows produces:

Code:

viza@anon:/$ sudo lsof | grep windows
viza@anon:/$

So windows isn't busy.
And the good old mount command produces:

Code:

mount: /dev/sdb already mounted or /media/windows busy

Code:

viza@anon:/$ uname -a
Linux anon 2.6.11-1-686 #1 Fri Feb 11 15:59:02 UTC 2005 i686 GNU/Linux

As well Nautilus now locks entire computer up requiring a cold reboot. Good thing I am a fluxbox user ; ). The default ubuntu gnome desktop freezes computer. According to logs it's a kernel panic. As well, I needed to increase the apt-get cache size considerably. I think something's bad on this kernel build, and it's some sort of disk IO thing.

Code:

update---
started up using 2.6.10 i386 and nautilus issue cleared up
mount is still busy. No more kernel panics tho...

If anyone knows what's going on here or has seen this, I would love to hear from you. I could mount this drive under dedrat fine.

thx,
viza

Okay, that's too heavy for me

ablewisuk · 09-06-2005, 10:35 AM

If anyone is still reading this thread: I had the same problem after installing a custom kernel and solved it by doing 'sudo apt-get remove evms'. It is apparently caused by the enterprise volume management service. This may remove some other packages, so be careful.

See here for more info: http://lists.debian.org/debian-user/.../msg00388.html

tunasashimi · 09-06-2005, 01:55 PM

Fan bloody tastic.. will report back if I can still find that drive....

Thanks...

Wonder why...
