Hi Raj,
Thank you for your response.
Please grep the log I sent with the keyword 'cupsd'.
You can find the records like:
Jan 05 20:55:39 gingitsune cupsd[7047]: Unable to change ownership of
"/var/log/cups" - Read-only file system
And here is the /etc/fstab attached.
The root file system is in /dev/sda1, a plain old HDD partition.
The problem occured without any USB disks.
