http://bugzilla.novell.com/show_bug.cgi?id=496520 Summary: can not write to dvd-ram with udf: UDF-fs Partition marked readonly; forcing readonly mount Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: i586 OS/Version: openSUSE 11.1 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: mail@Franosch.org QAContact: qa@suse.de Found By: --- User-Agent: Mozilla/5.0 (compatible; Konqueror/3.5; Linux) KHTML/3.5.10 (like Gecko) SUSE After mounting a DVD-RAM with an UDF file system on it with mount -t udf -o rw,noatime,async /dev/sr0 /media/cdrom the command 'mount' says ... /dev/sr0 on /media/cdrom type udf (rw,noexec,nosuid,nodev,noatime) but touch /media/cdrom/a fails with touch: cannot touch `/media/cdrom/a': Read-only file system In /var/log/messages appears: Apr 20 16:37:30 cell1 kernel: UDF-fs: Partition marked readonly; forcing readonly mount Apr 20 16:37:30 cell1 kernel: UDF-fs INFO UDF: Mounting volume 'LinuxUDF', timestamp 2006/03/20 10:07 (1000) This is the case with DVD-RAMs that have worked with Suse 10.2. Also, dvd-ram-control says dvd-ram-control -rdwr /dev/cdrom The disc is unprotected already. So, although the disc appears to be unprotected, and 'mount' says it is mounted rw, it is in fact mounted read only. Either 'mount' should say it is mounted 'ro' or you should be able to write to it. Neither is the case, which is a bug. Reproducible: Always Steps to Reproduce: 1. Put DVD RAM with UDF filesystem in drive. 2. mount -t udf -o rw,noatime,async /dev/sr0 /media/cdrom 3. touch /media/cdrom/a Actual Results: The 'touch' command fails, but should not. Expected Results: A file /media/cdrom/a should be written. Re-making the file system on the DVD with mkudffs --media-type=dvdram /dev/sr0 fixes the DVD-RAM and 'touch /media/cdrom/a' succeeds. So, apparently, the bug only occurs with certain DVD-RAMs or UDF file systems. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
