system hangs on shutdown
 

Redhat AS 3 update 1, Dell PE 1600SC w/duel procs, megaraid, standard uncompiled kernel

System is locking up on shutdown every time. I even tried rebooting in run levels 5, 3, and single user. It locks every time right after the message "INIT: No more processes left in this run level" gets displayed to the console.

Nothing is showing up in /var/messages. Last entries before the next [manual] boot are:
-----------------------------------------------------------------------------------------
Aug 26 16:45:21 lsdev nfslock: rpc.statd shutdown succeeded
Aug 26 16:45:21 lsdev portmap: portmap shutdown succeeded
Aug 26 16:45:21 lsdev kernel: Kernel logging (proc) stopped.
Aug 26 16:45:21 lsdev kernel: Kernel log daemon terminating.
Aug 26 16:45:22 lsdev syslog: klogd shutdown succeeded
Aug 26 16:45:22 lsdev exiting on signal 15
Aug 26 17:06:08 lsdev syslogd 1.4.1: restart. -------(next reboot starts)
Aug 26 17:06:08 lsdev syslog: syslogd startup succeeded
------------------------------------------------------------------------------------------

I have to hard-reset to reboot.

Any ideas?

Thank you,

Sounds to me like the system halt completed fine.

except I'm doing "shutdown -r now"

We have a similar problem - did you resolve your rebooting??

In the boot.log file, all shows "successful" except for one entry:

Feb 8 07:39:52 ns5 nfslock: rpc.statd shutdown failed

Nfslock does the file sharing and locking - after reboot, the httpd does not come up, attempts to restart result in:

error 30 read-only file system when it is attempting to write to the log files

... so we can't get info after that point.

Only solution = manual reboot

Any suggestions where to hunt down why nfslock does not shutdown and if that is the culprit??

Thanks!

Re: system hangs on shutdown
 

Have you tried disabling Plug 'n play support in your BIOS ? This has made a difference for me on SMP systems using FreeBSD in the past.

My AS3 server does the same thing a lot when a AMD/NFS connection goes bad.
If the shutdown does not complete but you still have a root terminal open try looking if any NFS mounts are still up. If they are, go and manually umount all of them using the -f and -l (lazy) option, and specify '&' so umount runs in the background.... then do another shutdown -h now immediately after that.
