I'm not exactly sure if such logs are preserved, but you can try :
and see if the result will show something relevant. In my case it will help me to understand the issue I have with automount my mp3 player, it shows the last time when this particular device has been un-mounted :

I would like to know if there is a command or set of commands that I can run to verify that there are no 'extraneous' nfs mounted filesystems on our server. I didn't see anything in doing a search on NFS.
We think that we may have some filesystems that are still nfs mounted when the link should... (3 Replies)
In my Solaris 10 based server, I have noticed the following mounts when a use DF -K
/dev/dsk/c0t0d0s0 5062414 3213876 1797914 65% /
/ 5062414 3213876 1797914 65% /net/se420
I understand the first mount because it appears in my vfstab file and is the mount of root that I would expect.... (1 Reply)
Hello,
I have a backup script that backs up my system to a nfs mounted file system. The mount point on my local system is /backup.
I want my script to check whether the nfs file system is mounted on /backup before actually backing anything up. Even if the nfs file system was NOT mounted,... (2 Replies)
how do you fsck the / filesystem? I know it does it automatically the next time I boot up following a switch on the wall shutdown but is there a flad somewhere that forces this on next boot up?
Thanks (2 Replies)
I am wondering if there is a way to search for top 10 files in size in root filesystem but exclude all other mounts including nfs mounts .
For example excluded
/var
/boot
/app
/app1
/u01/ (1 Reply)

I had a question in my test which asked where suppose user B has a program with 's' bit set. Can user A run this program and gain root privileges in any way?
I suppose not as the suid program run with privileges of owner and this program will run with B's privileges and not root. (1 Reply)

LAST,LASTB(1) Linux System Administrator's Manual LAST,LASTB(1)NAME
last, lastb - show listing of last logged in users
SYNOPSIS
last [-R] [-num] [ -n num ] [-adiox] [ -f file ] [ -t YYYYMMDDHHMMSS ] [name...] [tty...]
lastb [-R] [-num] [ -n num ] [ -f file ] [ -t YYYYMMDDHHMMSS ] [-adiox] [name...] [tty...]
DESCRIPTION
Last searches back through the file /var/log/wtmp (or the file designated by the -f flag) and displays a list of all users logged in (and
out) since that file was created. Names of users and tty's can be given, in which case last will show only those entries matching the
arguments. Names of ttys can be abbreviated, thus last 0 is the same as last tty0.
When last catches a SIGINT signal (generated by the interrupt key, usually control-C) or a SIGQUIT signal (generated by the quit key, usu-
ally control-), last will show how far it has searched through the file; in the case of the SIGINT signal last will then terminate.
The pseudo user reboot logs in each time the system is rebooted. Thus last reboot will show a log of all reboots since the log file was
created.
Lastb is the same as last, except that by default it shows a log of the file /var/log/btmp, which contains all the bad login attempts.
OPTIONS -num This is a count telling last how many lines to show.
-n num The same.
-t YYYYMMDDHHMMSS
Display the state of logins as of the specified time. This is useful, e.g., to determine easily who was logged in at a particular
time -- specify that time with -t and look for "still logged in".
-R Suppresses the display of the hostname field.
-a Display the hostname in the last column. Useful in combination with the next flag.
-d For non-local logins, Linux stores not only the host name of the remote host but its IP number as well. This option translates the
IP number back into a hostname.
-i This option is like -d in that it displays the IP number of the remote host, but it displays the IP number in numbers-and-dots nota-
tion.
-o Read an old-type wtmp file (written by linux-libc5 applications).
-x Display the system shutdown entries and run level changes.
NOTES
The files wtmp and btmp might not be found. The system only logs information in these files if they are present. This is a local configura-
tion issue. If you want the files to be used, they can be created with a simple touch(1) command (for example, touch /var/log/wtmp).
FILES
/var/log/wtmp
/var/log/btmp
