create zpool on existing directory with data

Create zpool on existing directory with data

APPLIES TO :  Oracle SPARC Solaris

ISSUE :  A directory contains a huge amount of data, due to disk space constrain we need to convert that data into zfs volume. The challenge is how to retain the file ownership, permission, and soft/hard links

GOAL :  Create a zfs volume and move the local data with exact permission, ownership.

SOLUTION :  There isn't a built-in or automated way to create a new DataSet and migrate existing data to it. To get it done you'll need to create the dataset and manually (e.g. rsync) the data to it.

Prerequisites :   NIL

               1. Move the data directory into a new name.
                       root@JUDI-DEV-10:/root # mv /oracle /oracle_org

               2. Create a zpool volume with a the new disk
                       root@JUDI-DEV-10:/root # zpool create -f -m /oracle oracle c1d1

               3. Copy the data to the zfs volume using the rsync command
                       root@JUDI-DEV-10:/root # rsync -aAX /oracle_org/ /oracle

               4. Verify the permission and ownership once the copy completed
                       root@JUDI-DEV-10:/root # ls -rlt
