Category: qemu Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Adrian Bridgett (abridgett) Assigned to: Nobody/Anonymous (nobody) Summary: repeatable corruption with qcow2 on kvm-79 Initial Comment: Creating a qcow2 image, mkfs.ext3, sometimes mounting it would fail immediately, but in all cases it would corrupt (overwritten with zeros) after starting up backuppc on it. This is KVM-79 on a Debian lenny host and guest. This occured using virtio or not. Swapping to a raw file or LV worked flawlessly. I've tested the box with memtest and I don't have issues elsewhere but I've seen corruptions on other images. host and guest are both 2.6.26-1-adm64 kernel (debian lenny) I'm running 32-bit userspace everywhere. Dual core Intel Core2 E6300. I see KVM-81 has "improve qcow2 data integrity with cache=writethrough" which _might_ be what I'm hitting - but I can't find more details about this to check (and backport patch to debian package or wait for newer debian package). thanks. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=2490866&group_id=180599 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
