Root @ RHEL4 ~] # servicesmartdstart Tip: start smartd failed root @ RHEL4 ~] # servicesmartdstatus Tip: smartd is dead, but sbusys locked root @ RHEL4 ~] # tail/var/log/messages-n15 Tip: Unabletoregisterdevice/dev/sda (noDirective-dremovable). Exiting.UnabletoregisterSCSIdevice/dev/sdaatline30offile/etc/smartd.con probably tips smart does not support SCSI devices, but do not understand why my virtual machine hard disk will be RHEL4 SCSI hard drives. I put at the service of this service to delete: chkconfig--delsmartd (3) insert a USB device mount host, winXP tips find device first, and on Linux through fdisk-l it didn't find the USB device. This can be done by VM-> RemovableDevices select Anonymous USB device address. Discovered by fdisk-l USB device name as sdb1.root @ RHEL4 ~] # mkdir/mnt/usbroot @ RHEL4 ~] # mount-tauto/dev/sdb1/mnt/usbroot @ RHEL4 ~] # umount/mnt/usb (4) shutdownshutdown is the safest way to shut down, it notifies all logged-on user system will be shut down and freeze login. direct power off, shutdown, or even delay the restart are possible.
