Mounting filesystem in read/write mode (HP-UX 11i)

[MDesai]

Hi,


I have created logical volume on which ISO filesystem is mounted as below

1. Created logical volume
lvcreate -n ISOLV 5000 /dev/vg00

2. Mount ISO:
dd if=installsoftware.iso of=/dev/vg00/ISOLV
To mount it read only mode on /dvdrom
mount -orr /dev/vg00/ISOLV /dvdrom

Please suggest how to mount ISO in read/write mode on /dvdrom.

Thanks and Regards,
M. Desai

I don't think this is possible. ISO fs is usually a static file system.

Hi Desai,

I can't test it now. But can you try this:

mount /dev/vg00/ISOLV /dvdrom

or mount -F cdfs -e -o rr /dev/vg00/ISOLV /dvdrom

Regards.

Shalom Desai,

Please suggest how to mount ISO in read/write mode on /dvdrom.

Impossible

/dvdrom

If its actually mounted on a dvd reader

rom

READ
ONLY
MEMORY

Can't mount it in read/write mode.

Not possible.

The iso9660 standard for CD/DVD filesystems (of which rockridge is an extension of) is a read-only filesystem.

With the right software, you can have multi-session support which would allow you to update the contents of the iso, but not in a standard r/w filesystem way - more like burning new data onto a DVD.

Read this section on multi-session support on the wiki page for iso9660:

I found this link - might help.

If you have ignite installed, it would be in this dir:

/opt/ignite/lbinia/dvd+rw-format

I have not tested it.

So growisofs may support multi-session capabilities, but it still won't allow you to mount an iso file in rw mode.

Thank you everyone for all responses.

My problem is solved now.

1. I was trying to modify one script after mounting ISO under /dvdrom. Since the script has /dvdrom path in many places, I was forced to install the software from /dvdrom. The ISO was mounted in read only mode so it was not possible to make any changes to the scripts.

Solution:
1. As per the usual procedure I had mounted software under /home/mydir. After mounting, I had copied all data under /dvdrom directory
2. Made necessary changes to the script under /dvdrom
3. Installed software as per the procedure.

Cheers!!!

Bye.
