Error ZFS mount point - problem
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,
Muthukrishnan G

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
