We bit the bullet and reinstalled two new nodes from debian to precise=20 in favour of possible performance increase?! *sigh*, still getting: 2012-11-06 17:05:51.863921 7f5cc52e3780 0 filestore(/data/osd6-3) moun= t=20 syncfs(2) syscall not support by glibc 2012-11-06 17:05:51.863925 7f5cc52e3780 0 filestore(/data/osd6-3) moun= t=20 no syncfs(2), must use sync(2). as a show-stopper.
