(2TB Hitachi SATA) ZFS is configured to start @ boot via 'zfs_enable="YES"' in the /etc/rc.conf. Creation Commands: # zpool create storage01 raidz2 da1 da2 da3 da4 da5 da6 da7 da8 da9 da10 # zpool add storage01 spare da11 da12 # zfs create storage01/tachyon # zfs create storage01/iron # zfs create storage01/boson # zfs create storage01/hydro >How-To-Repeat: Create a pool and then attempt to: # reboot or # shutdown -r now Result: Waiting (max 60 seconds) for system process `vnlru' to stop...done. Waiting (max 60 seconds) for system process `bufdaemon' to stop...done. Waiting (max 60 seconds) for system process `syncer' to stop...done. Syncing disks, vnodes remaining... (etc, etc).. done All buffers synced. zfs_umount:1005[0] Force unmount is experimental - report any problems. zfs_umount:1005[0] Force unmount is experimental - report any problems. zfs_umount:1005[0] Force unmount is experimental - report any problems. zfs_umount:1005[0] Force unmount is experimental - report any problems. zfs_umount:1005[0] Force unmount is experimental - report any problems. Uptime: <TIME> --- HANGS ---- >Fix: Note: You can get a clean 'shutdown -r now' after these edits. Unfortunately, 'reboot' still does not function and hangs the system. I believe 'reboot' does not trigger rc.shutdown and hence does not fire off the 'rcorder -k shutdown /etc/rc.d/*' that a 'shutdown' would. Edit /etc/rc.d/zfs as follows: ADD below '#REQUIRE: mountcritlocal': # KEYWORD shutdown ADD @ bottom of zfs_stop_main() subroutine/function: kldunload zfs.ko opensolaris.ko sleep 5 kldunload zfs.ko opensolaris.ko sleep 5 >Release-Note: >Audit-Trail: >Unformatted:
