If you want both servers to see the same volume, you need to use a
clustered filesystem. Something like gfs. Ext3 won't work.

Hi Alireza,

EXT3 assumes exclusive access to one system. Mounting a file system
designed for single node access from multiple nodes can cause corruption.


If you must use SAN, read up on GFS, global File Systems.

Alternatively, consider NFS, a common way to allow multiple systems to
access the same set of files.

Good luck.
