Multiple mounts

[ercolano]

I have booted Knoppix 5.1 from a USB stick

Here is fdisk -l

Disk /dev/sda: 163.9 GB, 163927522816 bytes
255 heads, 63 sectors/track, 19929 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 5 19929 160047562+ 7 HPFS/NTFS

Disk /dev/sdb: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sdb1 * 1 38913 312568641 7 HPFS/NTFS

Disk /dev/sdc: 1014 MB, 1014497280 bytes
65 heads, 32 sectors/track, 952 cylinders
Units = cylinders of 2080 * 512 = 1064960 bytes

Device Boot Start End Blocks Id System
/dev/sdc1 * 1 953 990704 b W95 FAT32
Partition 1 has different physical/logical endings:
phys=(967, 64, 32) logical=(952, 39, 32)


There are links for /dev/sda1 and /dev/sdb1 on the desktop, but if I open them up they always show the USB key /dev/sdc1

here is /etc/mtab
/dev/root / ext2 rw 0 0
/dev/sda1 /cdrom fuseblk ro,nosuid,nodev,noatime,allow_other,blksize=4096 0 0
/dev/sdb1 /cdrom fuseblk ro,nosuid,nodev,noatime,allow_other,blksize=4096 0 0
/ramdisk /ramdisk tmpfs rw,size=411948k,mode=755 0 0
/UNIONFS /UNIONFS aufs rw,br:/ramdisk:/KNOPPIX 0 0
/dev/sdc1 /cdrom vfat ro,nodev,fmask=0022,dmask=0022,codepage=cp437,ioch arset=iso8859-1 0 0
/dev/cloop /KNOPPIX iso9660 ro 0 0
/proc/bus/usb /proc/bus/usb usbfs rw,devmode=0666 0 0
/dev/pts /dev/pts devpts rw 0 0

As far as I can make out, there are multiple mount on /cdrom.

How do I correct this?

Post the contents of /etc/fstab file here.

I had exactly the same problem with my USB Knoppix. I installed Knoppix 5.1 on a USB stick and able to boot with this image, but after some playing around i started to realise it mounts the USB stick to multiple points. I tried to unmount this drive but it would not let me and told me it has mounted multiple times.

after that, i tried to boot with a CD copy of knoppix and this time it works correctly as /dev/sda1 is now my harddrive and i can mount and unmount it.

anybody has an idea how to fix this? I really liked to use the USB booting as it works a lot faster than the CD.

Hi and Welcome !

Boot up from USB stick again and execute df -h command. Post output here.

df -h

[skyrock]

Filesystem            Size  Used Avail Use% Mounted on
/dev/root             3.4M   23K  3.4M   1% /
/dev/sda1             1.9G  712M  1.2G  37% /cdrom
/ramdisk             1012M  5.3M 1007M   1% /ramdisk
/UNIONFS             1012M  5.3M 1007M   1% /UNIONFS
/dev/sdb1             1.9G  712M  1.2G  37% /cdrom
/dev/cloop            2.0G  2.0G     0 100% /KNOPPIX

the above was the df -h result from USB boot.

i tried to unmount both sda1 and sdb1, the error is "/cdroom is mounted multiple times" and cannot be unmount

anyone can give assistant to the above problem?

Put # sign before /dev/sda1 and /dev/sdb1 lines in /etc/fstab file.

#/dev/sda1 /cdrom fuseblk ro,nosuid,nodev,noatime,allow_other,blksize=4096 0 0
#/dev/sdb1 /cdrom fuseblk ro,nosuid,nodev,noatime,allow_other,blksize=4096 0 0

Execute this to unmount partitions.

umount /dev/sda1
umount /dev/sdb1

Try to mount both manually again.

[skyrock]

here's the result after I tried. It doesnt work.

knoppix@Knoppix:~$ #/dev/sda1 /cdrom fuseblk ro,nosuid,nodev,noatime,allow_other,blksize=4096 0 0
knoppix@Knoppix:~$ #/dev/sdb1 /cdrom fuseblk ro,nosuid,nodev,noatime,allow_other,blksize=4096 0 0
knoppix@Knoppix:~$ umount /dev/sda1
umount: /dev/sda1 mount disagrees with the fstab
knoppix@Knoppix:~$ umount /dev/sdb1
umount: /dev/sdb1 mount disagrees with the fstab
knoppix@Knoppix:~$

[devils casper]

knoppix@Knoppix:~$ #/dev/sda1 /cdrom fuseblk ro,nosuid,nodev,noatime,allow_other,blksize=4096 0 0
knoppix@Knoppix:~$ #/dev/sdb1 /cdrom fuseblk ro,nosuid,nodev,noatime,allow_other,blksize=4096 0 0

Do not execute those commands at prompt. Open /etc/fstab file and put # sign before those lines.

su -
nano /etc/fstab

Press Ctrl+X, Y and hit Enter key to save file.

here's what I did:

1. opened terminal and typed su -, then I saw shell prompt become root@knoppix:~#
2. typed nano /etc/fstab and entered into editor. found the lines as below:

/proc /proc proc rw,nosuid,nodev,noexec 0 0 /sys /sys sysfs
rw,nosuid,nodev,noexec 0 0 /dev/shm /dev/shm tmpfs
rw,nosuid,nodev,noexec 0 0 /dev/pts /dev/pts devpts mode=0622 0 0
/dev/fd0 /media/fd0 auto user,noauto,exec,umask=000 0 0 /dev/cdrom
/media/cdrom auto user,noauto,exec,ro 0 0 /dev/hdc /media/hdc auto
users,noauto,exec,ro 0 0
# Added by KNOPPIX
/dev/sda1 /media/sda1 ntfs noauto,users,exec,umask=000,uid=knoppix,gid=knoppix$
# Added by KNOPPIX
/dev/sdb1 /media/sdb1 vfat noauto,users,exec,umask=000,shortname=winnt,uid=knoppix id=knoppix,gid=knoppix 0 0

3. tried putting # sign infront of /dev/sdb1 and /dev/sda1, then save and umount but it says device is busy and cannot unmount.
