Hey Adarsh,
If no downtime then the only way is lock with write on the table, move to
the new space, create symlink, flush the table.
Remember, this symlinks will have issues if you execute any maintenance on
these tables which are moved.
Better idea - As the tables are MyISAM, move one database dir one at a time
by locking all tables and create a symlink for the database folder.

Dear all,
I am working on a stable solution for resolving Space Issue of data
directory of MyISAM tables.
We have a table of 70GB in /hdd-1/mysql_data path and there is 10GB space
available space in Hard Disk.Now the table expects to grow upto 150Gb.
I have some doubts regarding Symlinking a database. The steps involved are
:-
1. Shutdown the server.
2. Create a new directory and move your database to new drive.
3. Symlink the database in the original directory and change permissions.
This involves a lot of time to move 70Gb data to new place.
Well this wouldn't be the perfect solution I'm looking for.
Is there any particular solution that requires no server shutdown and any
client query operations affected and simply put new data into another
partition.
Would Partitioning is the only rescue operation?
Please help me to find a stable and standardized solution.
Thanks Regards
Adarsh Sharma
