That's pretty much what one of my test rigs is, except iscsi luns rather than virtio-blk. I haven't been able to reproduce the issues, so I'm kinda flying blind w.r.t. to testing them here. Can you get a trace of what is happening (xfs_trans*, xfs_log*, xfs_ail* tracepoints) so I can have a deeper look? Cheers, Dave. -- Dave Chinner david@fromorbit.com
