<DIV><SPAN class=796545222-13032007>I hit various kernel oops while running some
metadata intensive test on GFS2 filesystem. This volume is intended to be used
as local fileystem. So it was created using lock_nolock. Also no cman, fence and
any such things are running in the system.</SPAN></DIV>

newer kernel (2.6.21-rc), which I'm planning to do. Meanwhile I want to poll the
alias on such issues in GFS2. </SPAN><SPAN class=796545222-13032007>Ofcourse I'm
all ears on any other ideas to resolve this!</SPAN></DIV></DIV>
