Re: [Gluster-users] ext4 issue explained
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.

Gluster up to 3.3.0 is not. Is that it? Any ETA for Gluster 3.3.1? Regards, Rodrigo Severo -- --- Rodrigo Severo Fábrica de Idéias SBS Quadra 2 - Bloco S - Ed.

The change originated in 3.3.0-rc2, according to the post, and I'm running a kernel based on 3.2.0. ___ Gluster-users mailing list Gluster-users@gluster.org http://gluster.org/cgi-bin/mailman/listinfo/gluster-users

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. ___ Gluster-users mailing list Gluster-users@gluster.org http://gluster.org/cgi-bin/mailman/listinfo/gluster-users

If that is the problem, you can downgrade your kernel to before they backported the change (not sure which version that is though), or reformat your bricks xfs. Do you have a link to any info on that issue? Does it only affect RedHat, or does it also affect distros running new kernels? I am using ext4 rather than xfs because I was reliably able to make machines running xfs lock up (these are Ubuntu not RedHat BTW) just by throwing bonnie++ load at them, but not when running the same test on ext4.
