Hi,
I making a script to check nfs mount and unmount options.
After various findings, i didn't get any solution for that.
Can you please help me in making the script.
1) I have used,
Code:
if grep -qs '/var/JETSHARE' /proc/mounts; then
echo "It's mounted."
else
echo "It's not mounted.
Not worked
2)
Code:
mountPart=/var/JETSHARE
rootId=$(stat -c%d /)
mountId=$(stat -c%d "${mountPart}")
if (( rootId == mountId ))
then
echo "code for not mounted"
else
echo "code for mounted"
fi
Not worked
3) I am unable to trace out the filesystem (df -h) when NFS is unmounted. Box is in hung state when it is unmounted.
So, how can I know from the script when the nfs is unmounted

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.

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)

I have my Mac OS X program executing a shell script (a script that copies files to a drive). I want to make it so that the shell script automatically kills itself if it finds that the host .app is not running OR kill itself if the drive that it is copying files to has been unmounted. Right now what... (2 Replies)
Hey there, sorry if this is a bit too much of a noob question, trying to get to grips with a simple bash script - but i have done ZERO bash scripting.

Hi,
I have exported a few nfs mounts from one server to the nfs clients.
This is my nfs server dfstab :

# share <pathname>

umount
UMOUNT(8) BSD System Manager's Manual UMOUNT(8)NAME
umount -- unmount filesystems
SYNOPSIS
umount [-fv] special | node
umount -a | -A [-fv] [-h host] [-t type]
DESCRIPTION
The umount command calls the unmount(2) system call to remove a special device or the remote node (rhost:path) from the filesystem tree at
the point node. If either special or node are not provided, the appropriate information is taken from the list of filesystems provided by
getfsent(3).
The options are as follows:
-a All the filesystems described via getfsent(3) are unmounted.
-A All the currently mounted filesystems except the root are unmounted.
-f The filesystem is forcibly unmounted. Active special devices continue to work, but all other files return errors if further accesses
are attempted. The root filesystem cannot be forcibly unmounted.
-h host
Only filesystems mounted from the specified host will be unmounted. This option implies the -A option and, unless otherwise speci-
fied with the -t option, will only unmount NFS filesystems.
-t type
Is used to indicate the actions should only be taken on filesystems of the specified type. More than one type may be specified in a
comma separated list. The list of filesystem types can be prefixed with ``no'' to specify the filesystem types for which action
should not be taken. For example, the umount command:
umount -A -t nfs,hfs
umounts all currently-mounted filesystems of the type NFS and HFS. (The -a option only unmounts entries in the /etc/fstab list.)
-v Verbose, additional information is printed out as each filesystem is unmounted.
NOTES
Due to the complex and interwoven nature of Mac OS X, umount may fail often. It is recommended that diskutil(1) (as in, ``diskutil unmount
/mnt'') be used instead.

A umount command appeared in Version 6 AT&T UNIX.
