Application server operating system: Sles 10 SP3 x86
1.We ran the suse11-sp1-os: # shutdown -r now command to restart the host that was running services. The host failed to shut down and halted when it was powering off.
2.Shutdown failure log: Kernel BUG at fs/jfs/super.c:119.
Remove power from the host and power it on again. Then start the host.
Shutdown failure log: Kernel BUG at fs/jfs/super.c:119
We can see from the preceding figure that the system attempted to delete a device that was already mounted when it was shutting down. However, the device was being accessed at the time, as a result, the device failed to be deleted, and therefore the shutdown failed. The symptom was that the power-off process halted. This was due to a Linux kernel bug.
The shutdown operation must follow this proper sequence: stop services completely and then shut down the host.
