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 requ...

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
