Fyodor, what kernel were you using? Was it a RHEL 6.x kernel, like Christian? I haven't had an opportunity to play with Ceph in about six months, but when I did I was using a much more recent ext4 code base (backported onto 2.6.34, where as RHEL was based on 2.6.32, but more importantly we were much more aggressive at backporting fixes onto our kernel). I didn't see anything like what you're reporting. If this is with a much more recent kernel, I'd definitely be interested. Since the Ceph server is a pure userspace application, if you can cause file system corruption which e2fsck has to fix, that's definitely an ext4 bug. Regards, -- Ted P.S Ext4 in the RHEL 6.x kernel is I believe a technology preview, which means it might not get full support from Red Hat. Still, if you do see those sorts of problems with ext4 on a RHEL kernel, and you have a valid Red Hat support contract, I'd definitely encourage you to file a bug with the distro. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
