Hi,
anyone please let us know how to write shell script to find the missing mountpoints after server reboot.
i want to take the mountpount information before server reboot, and validate the mountpoints after server reboot if any missing.please let us know the shell script from begining to end as i don't have knowledge on scripting.
Thanks,
Venkat
Hi VenkatReddy786,
Welcome to forum, please use code tags for any commands or codes. you can go through once with all forum rules. Also let me give you some basic ideas here for same and please try it by yourself and let us know if you face any issues with what you would have tried so far.
i- you can make a script for checking mount points by using df command check them before and after activity and compare them after activity they should be same as before activity.
ii- To ake a permanent solution, you can check fstab file in /etc/fstab in case of bash , make sure here mount points are not soft. Meaning if they are mentoned as soft mount points they will not come up after reboot. This should be permanent fix for the issue.
EDIT: In case of solaris it should be /etc/vfstab .
kindly try out the steps and let us know if you face any issues.
Thanks,
R. Singh
Hi Venkst & Ravinder,
Please note that on Solaris there is not an
/etc/fstab
It is in fact;
/etc/vfstab
root@ekbvsollic01:~# cat /etc/vfstab
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#
/devices - /devices devfs - no -
/proc - /proc proc - no -
ctfs - /system/contract ctfs - no -
objfs - /system/object objfs - no -
sharefs - /etc/dfs/sharetab sharefs - no -
fd - /dev/fd fd - no -
swap - /tmp tmpfs - yes -
/dev/zvol/dsk/rpool/swap - - swap - no -
You can glean a great deal of additional information from the mount tab.

Hi Ravinder Singh
Thanks for prompt responce. I know how to check manually with df command, but i want to validate with shell scripting. I am at basic level. Coould you please help on how to write shell script for this.
Hello Dave,
I had immediately edited the same in my post.
Thanks,
R. Singh
Hi Guys,
Check the post again as I have subsequently updated with more information.
Dave
Hi Dave,Ravinder Singh,
I want to place the shell script on server to validate the mountpoints.i want shell script for this.It would be more helpfull if you guys provide the script.
Thanks,
Venkat
Hi Venkat,
Show me what you have and I'll see if I can help, the forum is here for people to help each other and to do that we have to have a starting place.
To benefit from being a member of the forum it is necessary to learn and if someone just provides you with a script you will not learn, have you searched the previous posts in the forum as the information is probably there.
Regards
Dave
Hi Dave,
I tried to search previous posts, but couldn't find anything related to this. Could you please provide shell script for this. i will test my server, and get back to you with result. Below is my plan to prepare shell script.
1) I want to take the mountpoint information before server reboot.
2) I want to validate the mountpoints after server reboot with comparision the information which we taken before server reboot.
3) I want output like mountpoints are not missed if not miss.
4) I want output like mountpoints are missed if missed.
Thanks,
Venkat
Due to missing sample data, following example is how it could work in theory. It may or may not work for you.
script to run before reboot: collect-info-pre.sh
#!/bin/bash
df -k | awk 'NR>1 {print $1}' >df.pre
script to run after reboot: collect-info-post.sh
#!/bin/bash
df -k | awk 'NR>1 {print $1}' >df.post
if $(diff -q df.pre df.post >/dev/null 2>&1); then
echo "No missing filesystems found."
else
echo "Missing filesystems:"
grep -vx -f df.post df.pre
echo "*** Further in-depth analysis is absolutely necessary! ***"
fi
Hi junior-helper,
I am appreciate for your help. I will test in server, and get back to you.
Thanks,
Venkata

Hi junior-helper,
I have tested your script, It is working, but got wrong output.
Output should come if part like "No missing filesystems found.", but came elase part.
Below is the output for your reference. Please check and get back to me with correction please.
FYI.

Hi Venkat,
Post the output of the following commands;
cat /etc/vfstab
AND
cat /etc/mnttab
It looks like you have a muxture of four different types of file systems here.
Also could you please use code tags.
Regards
Dave

Hi Venkat,
Your system currently has a number of different file systems types mounted, some of these seem to automount. This will mean that the mounted file systems can be changed simply by having someone else logged onto the server.
This will not be an easy script to write, mainly because of the auto mounter.
What you will probably have to do is prepare a list (one entry per line - like this) lets say file.txt,
/
/var
/etc/opt/opsware
This file will require to have a complete list of the required file systems.
Then you will have to do something like this.
#! / bin / bash
while read line
do
check the file system is mounted
done <file.txt
Here is an example of a subroutine that I would use it will check and report status that is all for "zfs" , beware the input file has different fields in it.
CHECKMOUNT ()
{
for FS in `cat ${FSFILE} | awk -F":" '{ print $1 }'`
do
if zfs list | grep "^${FS} " > /dev/null
then
MSG "${FS} is mounted"
ERR "Unmount all filesystems under ${FS} before re-running"
fi
done
}
In order to mount and error check failed mounts you will need to have several modules like to one above.
Regards
Dave
Hi Dave,
Thanks lot for your initiate on this.
Just i want to compare two files, one file is having mountpoint information with df -k before server reboot, another is having mountpoint information with df -k after server reboot. I need to find the missing mountpoint information with comparision of two files if mountpoints are missing after server reboot.I don't want script should mount missing mountpoints.I will contact SA if any mountpoint missed.I would be more appreciate if you prepare the script for this
Hi Venkat,
Before restart your host, you can take backup of your mount point by using
#df > df
It will store the all df data as a file in your home directory. You can verify it after reboot.
Hi seenuvasan,
We can do manuall check. I want to find with shell script.
Thanks,
Venkat
Try two changes:
-
diffinstead ofdiff -q -
/usr/xpg4/bin/grepinstead ofgrep

Oops...
Just i saw your output of vfstab. Seems very large one... tough to check manually everything.
Also its complicated to create script, only shell script experts can help you.
