...ble to get up Dom0 to work with infiniband, but not DomU. I am using Xen 3.0.2 with vmlinuz-2.6.16-xen and initrd-2.6.16-xen.img for DomU kernel and ram image respectively. I am getting the error of "Unknown symbol in module" when i am trying to insert infiniband modules ib_mthca.ko and ib_umad.ko to domU kernel. I made sure that the kernel was configured with infiniband support. However, the dmesg output does not show that domU recognized infiniband hardware at bootup. Should I be specifying anything about infiniband in domain config file? Any help very much appreciated, Thank you, Lami...

Is anyone using Gluster with the Rocks cluster system? If so, do you know if there is a Roll for Gluster? Or, do you have any advice about things to do and things to avoid doing? We're considering using Gluster with Infiniband on our cluster and trying to learn whether other people have done this so we can perhaps learn from their experience. Thanks. ..

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

To Harry Mangalam about Gluster/RDMA: make sure these modules are loaded # modprobe -v rdma_ucm # modprobe -v ib_uverbs # modprobe -v ib_ucm To run the subnet manager # modprobe -v ib_umad Make sure libibverbs and (libmlx4 or libmthca) RPMs are installed. I don't understand why they appropriate modules aren't loaded automatically. Could put something in /etc/modprobe.d/ to make this happen maybe? Infiniband should not require troubleshooting after 5-10 years of developmen...

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
