ZFS mount point - problem

Question

Hi,
We are using ZFS to take the sanpshots in our solaris 10 servers. I have the problem when using ZFS mount options.
The solaris server we are used as,
SunOS emch-mp89-sunfire 5.10 Generic_127127-11 sun4u sparc SUNW,Sun-Fire-V440Sys
tem = SunOS
Steps:
1. I have created the zfs pool named as lmspool
2. Then created the file system lmsfs
3. Now I want to set the mountpoint for this ZFS file system (lmsfs) as "/opt/database" directory (which has some .sh files).
4. Then need to take the snapshot of the lmsfs filesystem.
5. For the mountpoint set, I tried two ways.
1. zfs set mountpoint=/opt/database lmspool/lmsfs
it returns the message "cannot mount '/opt/database/': directory is not empty
property may be set but unable to remount filesystem".
If I run the same command in second time, the mount point set properly and then I taken the snapshot of the ZFS filesystem (lmsfs). After done some modification in the database directory (delete some files), then I rollback the snapshot but the original database directory was not recovered. :-(
2. In second way, I used the "legacy" option for mounting.
# zfs set mountpoint=legacy lmspool/lmsfs
# mount -F zfs lmspool/lmsfs /opt/database
After run this command, I cant able to see the files of the database directory inside the /opt. So I cant able to modify anything inside the /opt/database directory.
Please someone suggest me the solution for this problem. or anyother ways to take the ZFS snapshot with mounting point in UFS file system?..
Thanks,

You'll have to explain the problem clearer. What exactly is the problem? What is "the original database directory"? The thing with the .sh files? Why are you trying to mount onto something with files in it in the first place?
