Whoa!! Hang on a minute. Let's explain some things here.
Any one filesystem can only be mounted by one operating system at a time. Mounting the same filesystem on multiple machines is an instant recipe for corruption.
Sometimes storage systems (SANs, NAS's, etc) can be dual-tailed into two different machines but only when a suitable software suite (cluster software) is managing the ownership (at any one time) of each filesystem on the storage. Then, when a failover occurs, the (expensive) cluster suite will swap over the mounted filesystems from one system to another.
As Jim eluded to, the filesystem(s) can only be mounted by one O/S which controls file locking, file access (read/write), etc, and any second node needs to access those filesystems over the network (via NFS). So, repeat, mounting a filesystem on more than one system at the same time is big trouble. Make no mistake about that.
