[Pvfs2-users] Is there a way to prevent MPI-ROMIO access?

[Bill Wichser]

We'd finally like to run an fsck to try and clean up our pvfs2 
filesystem (see my previous post about kernel crashes) but are concerned 
about users' jobs still accessing the filesystem while we are running 
these checks.

 From the kernel interface, this is easy, we simply disable the kernel 
module.  The other method though, direct access via the API/MPI-ROMIO, 
remains an issue.  Is there some method we can use to disable access 
through this interface?  Or can we just run the fsck without worrying 
about this?

Thanks,
Bill
