Changing to read/write mode mounting Knoppix

**kermitq** · 09-02-2006, 06:19 PM

Hi all,

I use USB Flash Drive for Knoppix ,but it is mounted as read only media So the question is: how to set Knoppix's USB mounting from read-only to read-write. What script does mount Knoppix's media ?

Cheers!

Right click on the desktop icon of the drive and select "mount". Right click on the desktop icon again and select "Actions --> Make drive writable".

no, the problem is not so silly as You thought.

Harry, I You cant unmount partition that is used by the filesystem at the same time(in my case it is a usb stick wtih knoppix).

ockham23, yes i agree , but the usb is my knoppix media.

The question was: how to change the default read-only mode mounting to read write, not by simply unmouting and mounting in other mode, but changing the script which mounts drive on system init. Where could i find mentioned script ?

You didn't make it clear that you actually had knoppix on the USB device with the previous post. You said

That not quite the same as saying that you boot Knoppix from the USB device, it just implies that you have a USB stick that you want to use for Knoppix, perhaps to save data or programs.

I think you may have to partition the device as two partitions, on for the system and one for data.

Yes, I've just made two partitions.

But, I still return to my previous question. Is it possible set Knoppix for mounting its media to read/write mode ?

Maybe I understand what you mean.
I've experienced this isssue with 'exhotic' devices. With 'exhotic' I mean not simply usb_key but such devices as PSP(sony). Knoppix installs (not live_cd, not tried) completly fails to mount it. I can mount such devices only with a kanotix install, but they will be recognized as 'read_only_file_ system', and after an 'ls -l /media/sda1' check I have a result like:

Code:

-rx-r------- guest guest .....

And even after become root and giving a 'chmod 777 /media/sda1' command the shell again says 'read-only file system!'.

This not always happen and once I was able to mount a PSP on knoppix/kanotix_install with r/w rights.
To avoid the only_read_fs_issue maybe is necessary crete a filesystem from scratch [mkfs.vfat...], but not tried, being PSPs of costumers and not mine.

so the media on which knoppix is burned/copied ( cd, or usb ) cant be mouted as read-write even after changing some its internal scripts ?

**maxIT** · 09-03-2006, 04:50 PM

Last chanche (maybe), check '/etc/fstab' root mountpoint that being without read_only flag.
This is the file you call 'script' (actually it isn't a script, but a 'config file').
The below is mine, you can notice the 'ro' only in case of faulting-reboot, not default.

Code:

/dev/hda2  /  ext3  defaults,errors=remount-ro  0  1

yes i know what config file is

But knoppix adds autmaticaly lines to fstab. The Knoppix CD is add to fstab dynamically. and it is added as read-only (nothing strange if it is CD - but I use Knoppix on USB pendrive). I'm looking for scripts which adds these lines to fstab config file. Maybe in that script I could change mounting to read-write.
