http://bugzilla.suse.com/show_bug.cgi?id=1114113 Bug ID: 1114113 Summary: the latest LVM2 can overwrite extents beyond metadata area Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem Assignee: bnc-team-screening@forge.provo.novell.com Reporter: ghe@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I got a bug report from the upstream developer, he said, in the latest versions, LVM2 can overwrite extents beyond metadata area. A critical bug has been found in LVM which can cause data corruption in rare cases. Avoid using LVM commands that change Volume Group metadata (e.g. lvcreate, lvextend) while LVs in the VG are being used. An I/O bug can cause LVM commands to read and write back the first 128KB of data immediately following the LVM metadata at the start of the disk. If these blocks are being modified by another program (or file system) at the same time as the LVM command, then that program's changes could be lost. A fix is being evaluated and will be provided as soon as possible.
