As soon as I read it I noticed that I have the same kind of issue. I dug through the biozone to examine the leaked bio-s and they all seem to have bio_cmd = 5 and bio_flags = 8. So, they seem to be BIO_FLUSH bio-s. Their zio-s must have been ZIO_TYPE_IOCTL. Now, those zio-s use ZIO_IOCTL_PIPELINE and it is defined as: #define ZIO_IOCTL_PIPELINE \ (ZIO_INTERLOCK_STAGES | \ ZIO_STAGE_VDEV_IO_START | \ ZIO_STAGE_VDEV_IO_ASSESS) So, ZIO_STAGE_VDEV_IO_START is in the pipeline, but ZIO_STAGE_VDEV_IO_DONE is not as you have correctly theorised. The normal I/O pipelines always include ZIO_VDEV_IO_STAGES #define ZIO_VDEV_IO_STAGES \ (ZIO_STAGE_VDEV_IO_START | \ ZIO_STAGE_VDEV_IO_DONE | \ ZIO_STAGE_VDEV_IO_ASSESS) so the problem does not affect them. I will double-check why the ioctl pipeline omitted ZIO_STAGE_VDEV_IO_DONE and will test adding that stage. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
