shared disk, two hosts *without clustering* in linux
Thanks, and also to all other people responding.

Yes, i do consider any sort of Cluster File System, *but* only if it lets me the option of *not* clusterize also the hosts. i.e. clusterizing *only* the storage. (Independent hosts sharing only storage in a SAN, and with filesystem preferably).
Host A has application functionality "X", host B has "Y". Then if A is brought down, "X" funcionality ceases, but "Y" functionality remains, and host B still has the CFS available to R-W. Then, when A is available again, it 'sees' the changes applied to the shared cluster filesystem by B while A was knocked out. Strange, because with a standard cluster i know i would have both X and Y funcs. all the time, but i was asked exactly as i have said.
If that were *not* possible with some available Cluster F.S. under Linux, and then i am forced to take a "whole cluster" solution then, in order to respect the specification, i would needed to at least preserve exclusive application funcionality on each host, i. e. force "X" application functionality only on host A (and "Y" only on B). Up in this thread Faeandar said that force independent processes should not be a problem for most modern clusters. Now i am looking for one that is able to achieve it.
