Murali,
Thanks, that's the right command. Now that I see it I even
remember using it in the past, wrapped around the pvfs2-fsck!
We actually have a system reservation set for Monday morning so
once the jobs in the queue trickle down, we'll be able to start the
fsck.
pvfs2-fsck sets the admin mode before running, and puts it back to
normal mode once its done.

Hi Bill,
One way to do this is to switch the server to admin mode. I think you
can do that using pvfs2-set-mode in src/apps/admin.
After that the server won't take regular requests I think..
I don't know if the fsck app already does that..You will of course
need to switch the mode back after the fsck finishes...
It has been a while since I looked at that code.. so I could be
wrong.. :)
It would be best if you ask all users to kill their jobs before
running fsck..
Online fsck is probably going to cause a lot of grief if users are
actively using
the volume...
thanks,
Murali

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
