I help an NT admin that has recently added a redhat 8.0 based samba
server to his network. the share is one that is a core service for the
operation of the business and has about 50 users constantly accessing
data from several accounting and tax preparation applications.
One of the primary applications requires update farily recently as of
late and the admin is having problems getting all files in a specific
directory to release so they can be updated.
Procedure is that all users are asked to close the application and even
when they have all shut down the app, lsof still reports files in use by
smbd processes owned by root. Under normal circumstances lsof reports
files in use for the user logged on and usually several root owned
processes as well.
If I take the smbd pids that are there as root and grep the output of
netstat -ap I see that the smbd network connection is still active to
the machine.
What state is this process in? Is there some caching that occurs for a
period of time that allows the user to reattach to the smbd process or
what?
What is the best way to nicely clean up these processes?
Any insight appreciated.
Bret
here is some info
Inorder to track this down I use the following script
#!/bin/bash
DIR="/apps/Lacerte/02tax/"
#DIR="/var"
echo "All users with locks in $DIR"
declare -a PIDS
lsof +D $DIR |awk '{print $2 " " $3}'|sort -nu
echo "netstat connections for root owned pids"
PIDS=($(lsof +D $DIR |awk '/root/ {print $2}' |sort -u))
for pid in ${PIDS[*]}; do
netstat -ap |grep $pid; done
exit
Here is the output that illustrates the issue.
[root@solin bin]# lacerteuser.sh
