Fedora 12 : mount dmg-files

jonaskellens · 05-02-2010, 01:17 PM

Hello.

I'm trying to mount a dmg-file.

I'v done the following :

--> yum install hfsutils hfsplusutils

--> modprobe hfsplus

--> mount -t hfs -o loop file.dmg /mnt

I get :

Code:

[root@jonas jonas]# mount -t hfs -o loop file.dmg /mnt
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

dmesg shows :

Code:

hfs: can't find a HFS filesystem on dev loop0.

/var/log/messages says :

Code:

May  2 20:05:00 jonas kernel: hfs: can't find a HFS filesystem on dev loop0.

Isn't the hfs-filesystem installed and loaded ?!

I'm not 100% sure but I think hfs and hfsplus are two different filesystems. What happens when you try -t hfsplus instead of -t hfs? Ot better yet, omit the -t argument and let the kernel figure out the filesystem type (if it's one it recognizes, it will do so automatically).

fedora dose not allow direct mounting to /
so mounting it as /mnt will not work
try

Code:

mkdir /mnt/dmg
mount -t hfs -o loop file.dmg /mnt/dmg

Thank you for your reply. I really want to sort this out...

Code:

[root@jonas Desktop]# ls -l /mnt/
total 4
drwxr-xr-x. 2 root root 4096 2010-05-03 09:09 zumba

[root@jonas Desktop]# modprobe -l | grep hfs
kernel/fs/squashfs/squashfs.ko
kernel/fs/hfsplus/hfsplus.ko
kernel/fs/hfs/hfs.ko
kernel/net/sched/sch_hfsc.ko

[root@jonas Desktop]# mount -o loop -t hfsplus file.dmg /mnt/zumba/
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

[root@jonas Desktop]# dmesg | tail
...
hfs: unable to find HFS+ superblock
[root@jonas Desktop]# mount -o loop -t hfs file.dmg /mnt/zumba/
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

[root@jonas Desktop]# dmesg | tail
...
hfs: unable to find HFS+ superblock
hfs: can't find a HFS filesystem on dev loop0.

And a mount without filetype :

Code:

[root@jonas Desktop]# mount file.dmg /mnt/zumba/
mount: you must specify the filesystem type

Any ideas ?

Is anyone else able to mount dmg-files in Fedora 12 ?

the "file.dmg" is ON the ROOT's desktop ?
so you DID use the fedora hack to start Gnome GUI as ROOT
-- that is very ill advised - things will NOT WORK IN THE ROOT GUI !!!!

DO NOT TRY to mount a file from the root account desktop folder ( or even your normal user's .desktop folder )

i think everyone here( including me) thought you had the file.dmg in /

This file is not on root's desktop, but on my normal user's desktop :

Code:

[root@jonas Desktop]# pwd
/home/jonas/Desktop

I just placed the file their for easy access...

It makes no difference :

Code:

[root@jonas Documents]# pwd
/home/jonas/Documents
[root@jonas Documents]# mount -o loop -t hfs file.dmg /mnt/zumba/
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

[root@jonas Documents]# mount -o loop -t hfsplus file.dmg /mnt/zumba/
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

Code:

[root@jonas Documents]# dmesg | tail
hfs: can't find a HFS filesystem on dev loop0.
hfs: unable to find HFS+ superblock

I don't think the place of the file.dmg is the problem, I think the problems lies with the HFS-filesystem.
Is this HFS-filesystem working for any Linux-user ??
