mount/unmount hfs and hfs+

[trash]

Can anybody tell me why I can mount, read/write but I can't unmount... it always tells me that the devices are busy

etc/fstab:
dev/hda10 /mnt/macos hfs defaults,noauto,user,rw 0 0
dev/hda11 /mnt/macosx hfsplus defaults,user,noauto 0 0


thanks

I am trying to have my two mac partitions show up under the /mount folder in my Ubuntu PPC operating system.
I have so far done:
mkdir /mnt/macboot <-----for my "main" mac partition, formatted as HFS
mkdir /mnt/110gbHFS <----for my +/-100gb storage partition, formatted as HFS

Here's the output of fdisk -l:
root@ubuntu:/home/brian # fdisk -l
/dev/hda
# type name length base ( size ) system
/dev/hda1 Apple_partition_map Apple 63 @ 1 ( 31.5k) Partition map

/dev/hda3 Apple_HFS Apple_HFS_Untitled_7 64749568 @ 262208 ( 30.9G) HFS

/dev/hda9 Apple_Free Extra 11888 @ 312569920 ( 5.8M) Free space


Here's my /etc/fstab file:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/hda8 / ext3 defaults,errors=remount-ro 0 1
/dev/hda2 none swap sw 0 0
/dev/hdc /media/cdrom0 udf,iso9660 ro,user,noauto 0 0
/dev/hda3 /mnt/macboot hfs defaults,umask=0,quiet 0 0
/dev/hda7 /mnt/110gbHFS hfs defaults,umask=0,quiet 0 0


Now, when I view the macboot or 110gbHFS folders, they are empty.
In terminal I typed:
mount /mnt/macboot
mount /mnt/110gbHFS

each time I received the following reply:
mount: wrong fs type, bad option, bad superblock on /dev/hda3,
or too many mounted file systems

wrong fs type, bad option, bad superblock on /dev/hda7,
or too many mounted file systems


So, I need a bit of help here! I have my directories showing up in the /mnt directory, but no data inside. How can I get access to my drives?

I am a newbie, and thought it may be better to use this thread rather than start a new one.
I appreciate any support.
Thanks!!

howdy Brian,
I would try...

/dev/hda3 /mnt/macboot hfs noauto,user,rw 0 0
/dev/hda7 /mnt/110gbHFS hfs noauto,user,rw 0 0

I'm not sure what 'umask=0,quiet' is supposed to do but i guess you can keep it in there and see if it works

[Brian McConnell]

Thanks for the suggestion. I cut and pasted it into fstab. still same reply as previous. I'm a bit stumped as I've used this method on a pc Ubuntu install with no probs. I'm wondering if there is a problem if, say, the partitions are HFS with journaling enabled.
:scratching head:

I'm wondering about the bad superblock possibility and what it means. Is it something that is correctable?

[trash]

i still get that 'bad superblock' with my cd sometimes and i used to get it with my mac partitions until I finally got the fstab right.... dunno what to say it looks like it should go... have you tried restarting?

[Brian McConnell]

yep, restarted. still no luck. I'm out of ideas, myself.

Make sure when you run the mount command in the terminal you also point it
to a device and not just the mount point like this:

mount /dev/hda3 /mnt/macboot
mount /dev/hda7 /mnt/110gbHFS

The /dev/hda# part tells the mount command which device contains the
filesystem you want to mount at the specified mount point. You may already
know this but I just wanted to make sure. Also, you may have to specify what
type of filesystem you are trying to mount so you could enter your command like this:
mount -t hfsplus /dev/hda3 /mnt/osx
