I'm experiencing a similar issue, albeit with slightly different hardware. I have several VMs backed by SAN storage, accessed through a QLogic 2560 controller. All of my volumes that are <1TB seem to function without issue. On the larger volumes (one in particular is >7TB with an XFS filesystem), I get near constant corruption whenever I copy a large volume of data (50-100GB). I switched the VM guest to use IDE instead of virtio, and the corruption was less frequent but didn't disappear altogether.
I've mounted the SAN volumes on the host and done 100GB+ copies without going through KVM and they worked flawlessly, so I can rule out the SAN setup as being problematic. -- kvm + virtio disk corrupts large volumes (>1TB). https://bugs.launchpad.net/bugs/574665 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
