All,

The hdd3 partition of my C3100 hard disk is mounted as read-only. I have tried a number of ways to resolve this, still no joy.

The first strategy was to remount it with: mount -o remount.rw /dev/hdc3. This didn't work as I consistently get the "Device or resource busy" error message. I've also tried to add rw to the mount options in the /etc/fstab file, still no joy.

All be grateful for any hints in resolving this.

Thanks in anticipation,
Ashu

Hi Ashu,

I had this too on my first C3000.
It was due to a file system error.

If you unmount it, then do an fsck.vfat -v-r /dev/hda3 (or /dev/hdc3, depending on if you booted without or with a CF card inserted, as far as I recall), you will maybe find that error.

In my case fsck was not able to fix it and I had to reformat the drive.

In that case, try to find out which file is the bad one. In my case, I could remount rw the drive, but on each attempt to save the KO/PI data file, it got remounted ro again.
That way I found out that this file was the bad one.

I copied it to another file with different name and configured KO/PI to use that new file. That way I was able to continue to use the drive with the bad file in constant rw mode. Just make sure the bad file isn't used anymore. Using it (or writing to it, to be more precise) triggered the remount read-only.
But as a longterm solution I stronly recommend to let fsck repair the FS or to reformat it entirely.

Good luck!
daniel
