https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D276420 Bug ID: 276420 Summary: zfs panic: VERIFY(zio->io_stage =3D=3D ZIO_STAGE_VDEV_IO_START) failed Product: Base System Version: 13.2-STABLE Hardware: Any OS: Any Status: New Keywords: crash Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: jfc@mit.edu I started a dd command to copy data between ZFS volumes in different pools.= I returned to find my system had rebooted. Unfortunately there was not enough space to save a dump. All I have is the syslog message: savecore[1921]: reboot after panic: VERIFY(zio->io_stage =3D=3D ZIO_STAGE_VDEV_IO_START) failed There are two such assertions in sys/contrib/openzfs/module/zfs/zio.c, one = in zio_vdev_io_bypass and the other in zio_vdev_io_reissue. dd block size argument was bs=3D1m. Transfer rate was about 100 MB/s. Ser= ver has 160 GB RAM. Source disk was SAS SSD, destination was raidz2 with 5 spinning SATA disks. Both pools have a cache on different partitions of the same NVMe drive. Kernel has 13.2 changes through 4c4633fdffbe8e4b6d328c2bc9bb3edacc9ab50a. --=20 You are receiving this mail because: You are the assignee for the bug.=
