There is a logical volume created as file system and mounted as /abc.
1) Can I change the mounted name?
2) If yes, will it affect the end users that are using this file system?
3) What is the command to change it? How about in SAM?
4) The shadow password is not applicable for trusted system. Am I right? But as I know, it is a new HP feature.
regards
Solved! Go to Solution.

Solution1. Yes
2. Yes, but in order to change the filesystem name you need to unmount the filesystem, which you won't be able to do if processes are using the filesystem.
3. Unmount the current filesystem, create a new empty directory with the desired name, mount the logical volume using the new directory name, change the /etc/fstab entry for this filesystem to reflect the new name
4. Yes, Shadow is independent of Trusted.

Re: Change mounted file system name
Very rightly explained by Dave..just to add something..
Make sure that no user uses the old mount point path.
for e.g Your are changing mount point from /abc to /xyz then:
The entire file structure in the filesystem will accessed with the path starting with /xyz/../..
So this should be oaky with all users.
Hope that helps.

Re: Change mounted file system name
1)YEs
2)yes only till the time you mount and unmount the filesystem the user won't be able to access that filesystem
3)Create the directory where you want to mount the filesystem, fstab file change the name of the directory therecorresponding to that filesystem,unmount hte filesystem & mount it again.
4) NO,shadow password is not applicable for Trusted systems.
I am assuming that you don't have any application (or dependent application using the filesystem by that ndirectory name) &
It's a pure data filesystem & you are very well versed with the impact of change from the software point of view.

Re: Change mounted file system name
You cannot unmount the filesystem till you kill all the processes running using that filesystem.
If you cannot unmount that means you cannot change the mount point....

Re: Change mounted file system name
What you mean is if there is a user open a file at this file system, when I doing the unmount, system will prompt me an error and the unmount process is fail. Am I right?
How about if the logical volume created as raw device which has an application (informix)? Can I rename the mounted file system with the above proposed steps?
regards.

Re: Change mounted file system name
If any user is using the files on the mounted file system..then umount will give you "device busy error" and won't allow you to unmount.
In that case you either issue "wall" command to notify all users about this activity or use fuser command to kill the associated processes with the fielsystem.
Suppose it is mount on /abc then
# fuser -cu /abc
Give you the list of active users
# fuser -kuc /abc
This will forcefully kill all user processes and then you will be able to umount the filesystem.
Hope that helps.
