Keep in mind though that a user may still be logged in even though the auth.log file shows that they logged out, so a part of the scripts should check to see if the mounts are already mounted at a user login, another part of the script should check to see if the user is still logged in under a separate session when they close a session.

Each time a child terminates, init records the fact and the reason it died in /var/run/utmp and /var/log/wtmp, provided that these files exist. CHANGING RUNLEVELS After it has spawned all of the processes specified, init waits for one of its descendant processes to die, a powerfail signal, or until it is signaled by telinit to change the system ...
I find also by this one “pcs resource create nfsshare Filesystem device=/dev/sdb1 directory=/nfsshare fstype=xfs –group nfsgrp”.

sar -P ALL -f /var/log/sa/sa10 Displays CPU usage broken down by all cores for the 10day day of the month from sa10 file. 3. Memory Free and Used (sar -r) This reports the memory statistics. “1 3” reports for every 1 seconds a total of 3 times. Most likely you’ll focus on “kbmemfree” and “kbmemused” for free and used memory.
A sysctl called vfs.nfsd.srvmaxio has been added that can be used to increase the NFS server’s maximum I/O size from 128Kbytes to any power of 2 up to 1Mbyte. It can only be set when the nfsd threads are not running, and will normally require an increase in kern.ipc.maxsockbuf to at least the value recommended by the console log message ...
When you start the nfs service, the /usr/sbin/exportfs command launches and reads this file, passes control to rpc.mountd (if NFSv3) for the actual mounting process, then to rpc.nfsd where the file systems are then available to remote users.
