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
