I tried version 8.4.11 and the problem persists. When using Qemu/KVM virtio disk with a caching mode that uses host page cache, or when using just a filesystem like ext4 on (without Qemu/KVM) on the host, the drbd device gets out of sync after a while. The drbd device is on top of a LVM-lv on both nodes. Is there anything else I can test? According to some (old) posts, this is a known issue for a long time now. But I never found any resolution or fix. Thanks. Armin _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
