RDMA Problems with GlusterFS 3.1.1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Whenever I try to start or mount a GlusterFS 3.1.1 volume that uses
RDMA, I'm seeing the following error messages in the log file on the
server:

On the client, I see:

initialization failed

This results in an unsuccessful mount.

I created the mount using the following commands:
/usr/local/glusterfs/3.1.1/sbin/gluster volume create testdir
transport rdma submit-1:/exports
/usr/local/glusterfs/3.1.1/sbin/gluster volume start testdir

To mount the directory, I use:
mount -t glusterfs submit-1:/testdir /mnt/glusterfs

I don't think it is an Infiniband problem since GlusterFS 3.0.6 and
GlusterFS 3.1.0 worked on the same systems. For GlusterFS 3.1.0, the
commands listed above produced no error messages.

If anyone can provide help with debugging these error messages, it
would be appreciated.
