I'm on Ubuntu 12.04 with a 3.2.0 kernel - so this shouldn't affect me, as long as the Ubuntu people don't backport this patch as well :-) Cheers, Brian.

Just want to add that we are working on a fix, but some of the proposed patches cause regressions with NFS and a couple of other things. You can track progress on gerritt here: http://review.gluster.com/3679 and http://review.gluster.com/3756 The bugzilla report (838784) is here: https://bugzilla.redhat.com/show_bug.cgi?id=838784 We will let you know when patches are merged that resolve this issue. -JM ----- Original Message -----> Brian Candler asks:> > On Tue, Aug 14, 2012 at 12:19:10AM -0700, Joe Julian wrote: > > > > I'm betting that your bricks are formatted ext4.
