Re: Regarding GFS (was: redhat-list Digest, Vol 96, Issue 1)

You will need to make sure whether you are referring to Red Hat GFS or
IBM GFPS as those are very different technologies.  The following will
assume Red Hat GFS.

GFS does not protect against disk failure.  It does, however,
contribute to protecting against node failure.  In order not to turn
the thread into a GFS course, I'd suggest you ask precise questions
and we shall formulate replies.

Good luck,
