Lightbulb Sharing SAN disk with multiple severs

Hi ,

I had a requirement to share a san disk between two rhel severs. I am planning to discover the same disk in two rhel nodes and mount it. Is it a feasible solution? and what kind of issues we may encounter mounting same disk in two OS's parallel ?

No, not just like that that. You would need some form of clustering with a shared logical volume manager and a shared filesystem... Just mounting two filesystems will lead to corruption.

To be more precise, you really just need a shared file system, whatever one you may chose.

What that file system then requires might very well include clustering and/or a shared volume manager.
