10031.0. "Why does /usr insist on an fsck after controlled shutdown" by NNTPD::"[email protected]" (Ken Miller) Tue Jun 03 1997 12:31

Hi,

I've got a customer who's running V3.2G on a 4000 (C2 Security, special
auditing appl) and a system disk with 6 ufs disk partitions and a swap
partition all on one disk (none of them overlapping).

The problem is starting about 2 weeks ago, /usr declares "Dirty File System"
whenever they reboot.  Even sync;sync;sync followed by a "shutdown -h now",
and then >>> boot drops them in single-user reporting a "dirty /usr".  An
fsck -Y /usr always yields no errors, and can be mounted and used with no
problems until the next reboot.

The only processes running are system processes (including ypserv & audit) and
the customer's audit appl, but they'd all been running with no updates for 
several months before this started happening.

Any ideas on how to further nail down the problem?  It's a secure site, so
it's
rather difficult to get access to.  Thus, I'd like to collect several ideas
before I get back on the machine.

Thanks in advance,

         == ken miller ==

>Even sync;sync;sync followed by a "shutdown -h now",

The prefered way to shut down a system is to use init if you 
want a clean shutdown rather than litterally just shut it all 
down now.  

Init runs the rc*.d shutdown scripts and generally should shut
off all those little processes that are still writing to or
reading from  /usr and causing it to be unclean when you reboot.

    So does shutdown, if you take away the "-h" option.
