[Bug 621177] New: EXT4 file corruption with ftruncate()
http://bugzilla.novell.com/show_bug.cgi?id=621177 http://bugzilla.novell.com/show_bug.cgi?id=621177#c0 Summary: EXT4 file corruption with ftruncate() Classification: openSUSE Product: openSUSE 11.3 Version: RC 2 Platform: x86-64 OS/Version: openSUSE 11.3 Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: emendonca@novell.com QAContact: qa@suse.de Found By: Field Engineer Blocker: Yes Using ftruncate() on a file in an EXT4 filesystem will cause severe file corruption. This is specially true if using VirtualBox, which uses this constantly for virtual disk management. In fact, it will corrupt running VMs, which will show random file system errors. The upstream bug is described here (kernel.org): https://bugzilla.kernel.org/show_bug.cgi?id=16165 Oracle has released a workaround for the problem with release 3.2.6. The problem has been verified on both OpenSUSE 11.2 (with kernel-desktop-2.6.31.12-0.2) and with OpenSUSE 11.3 RC2 (kernel-desktop 2.6.34-12.1). To reproduce the problem, use the testcase from the upstream bug (aio_corrupt.c). I've checked for similar reports on bugzilla, but none seem to address this particular error. -- 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.
