I want to test the ZFS raidz expansion feature. I have create a VM with vm-bhyve: # vm iso https://download.freebsd.org/snapshots/amd64/amd64/ISO-IMAGES/15.0/FreeBSD-15.0-CURRENT-amd64-20240718-a4469a0d19b6-271237-bootonly.iso # vm create fbsd15-bis I have increased the VM memory to 2G: # cat fbsd15-bis.conf loader="bhyveload" cpu=1 memory=2G network0_type="virtio-net" network0_switch="public" disk0_type="virtio-blk" disk0_name="disk0.img" uuid="ff66b6cc-459e-11ef-92b1-c86000cc94af" network0_mac="58:9c:fc:0a:ad:da"
# vm install fbsd15-bis FreeBSD-15.0-CURRENT-amd64-20240718-a4469a0d19b6-271237-bootonly.iso After the installation I have create 3 additional disks: in the host: # truncate -s 10G disk1.img # truncate -s 10G disk2.img # truncate -s 10G disk3.img I have added 3 additional disk: # cat fbsd15-bis.conf loader="bhyveload" cpu=1 memory=2G network0_type="virtio-net" network0_switch="public" disk0_type="virtio-blk" disk0_name="disk0.img" disk1_type="virtio-blk" disk1_name="disk1.img" disk2_type="virtio-blk" disk2_name="disk2.img" disk3_type="virtio-blk" disk3_name="disk3.img" uuid="ff66b6cc-459e-11ef-92b1-c86000cc94af" network0_mac="58:9c:fc:0a:ad:da" # vm start fbsd15-bis in the VM: # zpool create tank raidz1 vtbd1 vtbd2 # zpool attach tank raidz1-0 vtbd3 panic: VERIFY(vd == vd->vdev_top) failed cpuid = 0 time = 1721375688 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe00546d1800 vpanic() at vpanic+0x13f/frame 0xfffffe00546d1930 spl_panic() at spl_panic+0x3a/frame 0xfffffe00546d1990 zio_vdev_io_start() at zio_vdev_io_start+0x637/frame 0xfffffe00546d19e0 zio_nowait() at zio_nowait+0x10c/frame 0xfffffe00546d1a20 vdev_check_boot_reserve() at vdev_check_boot_reserve+0x7a/frame 0xfffffe00546d1a50 spa_vdev_attach() at spa_vdev_attach+0x700/frame 0xfffffe00546d1ad0 zfs_ioc_vdev_attach() at zfs_ioc_vdev_attach+0x75/frame 0xfffffe00546d1b10 zfsdev_ioctl_common() at zfsdev_ioctl_common+0x4f4/frame 0xfffffe00546d1bd0 zfsdev_ioctl() at zfsdev_ioctl+0xfb/frame 0xfffffe00546d1c00 devfs_ioctl() at devfs_ioctl+0xd1/frame 0xfffffe00546d1c50 vn_ioctl() at vn_ioctl+0xbc/frame 0xfffffe00546d1cc0 devfs_ioctl_f() at devfs_ioctl_f+0x1e/frame 0xfffffe00546d1ce0 kern_ioctl() at kern_ioctl+0x286/frame 0xfffffe00546d1d40 sys_ioctl() at sys_ioctl+0x12d/frame 0xfffffe00546d1e00 amd64_syscall() at amd64_syscall+0x158/frame 0xfffffe00546d1f30 fast_syscall_common() at fast_syscall_common+0xf8/frame 0xfffffe00546d1f30 --- syscall (54, FreeBSD ELF64, ioctl), rip = 0xb2fddfff8fa, rsp = 0xb2fcf7fe8d8, rbp = 0xb2fcf7fe940 --- KDB: enter: panic [ thread pid 958 tid 100176 ] Stopped at kdb_enter+0x33: movq $0,0x1058552(%rip) -- Regards, Maurizio
