Directories gets deleted !!!Confused !!!

I have been running few steps but whenever I run:
# mount -a

The Directories gets deleted.

Here are the steps I have been following:

Code:

PATH_RPM=/var/tmp/Mplus

#Creating the fsadmin folders and user IDs
cd /home/
mkdir fsadmin
useradd -c "Feature Server User" -d /home/fsadmin -m  fsadmin
cd fsadmin
mkdir logs
mkdir archive
mkdir tomcat
mkdir traces
mkdir mysql

#Mount the logical volumes Created
echo "/dev/lvm01-lvfs.vol on /home/fsadmin type ext3 (rw)" >> "/etc/fstab"
echo "/dev/lvm01-lvfslog.vol on /home/fsadmin/logs type ext3 (rw)" >> "/etc/fstab"
echo "/dev/lvm01-lvfstomcat.vol on /home/fsadmin/tomcat type ext3 (rw)" >> "/etc/fstab"
echo "/dev/lvm01-lvfstrace.vol on /home/fsadmin/traces type ext3 (rw)" >> "/etc/fstab"
echo "/dev/lvm01-lvfsarchive.vol on /home/fsadmin/archive type ext3 (rw)" >> "/etc/fstab"
mount -a

When I run the mount -a seen above all the directories manually created like logs,archive,tomcat gets deleted.

Anyone having idea why is is behaving so?

How about umount the /home. I think your created directories will appear again.

Check the /etc/fstab see whether there is a mount point for /home.

You are mounting to a directory (mount point) after creating the subdirectories. Whenever you mount (connect) something to the filesystem tree, it hides what was there previously.

Let's assume that /home/username is on one partition (or drive) and that the logical volumes are on another. You create directories in /home and they (and their data) are stored on that partition. If you then mount a different partition to /home/username, you will see the contents of the new partition. The old stuff is still there and can be seen by simply unmounting the new.

I'm surprised there weren't error messages from mount -a. As soon as something was mounted to /home/fsadmin, those subdirectories would have become hidden.

The error messages might be there in the log. Or they might not. This has the look of a batch script. I would like to see that fstab printed out if he has run this several times.

Could be that whatever is mounted on /home/fsadmin now has directories named logs, tomcat, traces, archive and each of those has something mounted.
