gluster volume info gives:

Volume Name: glusterKumiko
Type: Distribute
Volume ID: f54efdc7-0664-409d-b3bc-c39f31040f5e
Status: Started
Number of Bricks: 4
Transport-type: tcp
Brick1: kumiko01IB:/mnt/raid6
Brick2: kumiko02IB:/mnt/raid6
Brick3: kumiko03IB:/mnt/raid6
Brick4: kumiko04IB:/mnt/raid6

Also, the file /etc/glusterfs/glusterd.vol have the following content:

volume management
     type mgmt/glusterd
     option working-directory /var/lib/glusterd
     option transport-type socket,rdma
     option transport.socket.keepalive-time 10
     option transport.socket.keepalive-interval 2
     option transport.socket.read-fail-log off
#   option base-port 49152

Should I be worried that rdma is listed as transport-type (and the lack 
of tcp)?

Probably messed up:

1. When the volume was created (with RDMA) two of the bricks were 
populated with files I wanted to "merge into" gluster. It seemed as if 
they became "incorporated" after doing a "rsync -vaun" from our primary 
file system (the system in question is used as a mirror).

2. At a later time I wanted to go away from RDMA (using IPoIB instead), 
and at that time I removed the old volume, followed hints from


and created the new volume (with tcp instead of rdma).

3. Just recently I upgraded to 3.4.2-1, and started a

gluster volume rebalance glusterKumiko fix-layout start (since I have a 
lot of
"disk layout missing" and "mismatching layouts" in the logs).

Regards, and thanks!
