Shell Programming and Scripting

I have a single Linux Red Hat 8.0 server with two external disk arrays (each a raid) connected via SCSI. The OS/boot/swap is on an internal set of disks and should not be affected by this process.

I need to move all of my data from one disk array to another while keeping all of my 30 or so shares and permissions intact as possible. Each disk array is about 2000Gb and has a single partition/mount. Both disk arrays are connected and in production. Currently each disk array is less than half full so there is room to move all the data on to a single array thereby freeing up the other array. I have about 15 Samba shares on each array. My partitions are mounted as /data/sdc (array 1 ) and /data/sdd (array 2).

I need to remove arrays 2 for major maintenance. I could do all of these steps manually but I would like to script this process if possible (unless its not worth it).

My thought was to make a script that would do the following:

Manually
-create list of the shares and/or folders to be moved.
Script
-Read the list.
-Take the first Samba share offline (disabled if that is possible.)
-Copy (or move) the corresponding folder to the other partition.
-Edit the Samba config to reflect the new path of the share.
-Turn the corresponding share back on line (enable.)
-Once first share/move is done, move on to the next in the list. (loop this until complete.)
(-use verbose logging and pipe results to a log file.)
-Done.

The copying or moving of all the files will take quite a while but if I only do one share at a time I will minimize the impact on my users. Also I could kick off in the evening and have it hopefully complete on its own. I am not sure how it will deal with open or locked files.

I am not a programmer so I am not sure where to start. Any thoughts or existing scripts?

Thanks
