...tel Xeon E5-2670 CPUs and 42GB of memory. SR-IOV is enabled in the system BIOS along with VT-X, and of course VT-d. This system is a RHEL/CENTOS 6.4 x86_64 Dom0 running a 3.9.3-1 kernel with Xen 4.1.2 installed and intel_iommu enabled in the kernel. The advantage of this kernel is the built-in mlx4_core/en/ib kernel modules which support SR-IOV added in versions 3.5 and above. The basic OFED drivers provided by Mellanox do not compile with a custom Dom0 kernel (even the 2.0-beta OFED drivers), so a 3.5 or newer linux kernel is necessary. I updated the firmware on the ConnectX3 provided by Mellanox...

Hi have what might be some elementary questions. Really, what I"d love would be for someone who has had good success to publish his/her configuration files and, maybe, the output from ifconfig. At this point, when I see the not-so-good performance I"m getting, I don't realistically know if I'm in the right ballfield. It seems to me, that with so many mellanox cards out

An user reported that he has hit an annoying deadlock while playing with ceph based on btrfs. Current updating device tree requires space from METADATA chunk, so we -may- need to do a recursive chunk allocation when adding/updating dev extent, that is where the deadlock comes from. If we use SYSTEM metadata to update device tree, we can avoid the recursive stuff. Reported-by: Jim Schutt

After running ceph on XFS for some time, I decided to try btrfs again. Performance with the current "for-linux-min" branch and big metadata is much better. The only problem (?)
